• mysqlpump Invocation Syntax

• mysqlpump Option Summary

• mysqlpump Option Descriptions

• mysqlpump Object Selection

• mysqlpump Parallel Processing

• mysqlpump Restrictions

• Parallel processing of databases, and of objects within databases, to speed up the dump process

• Better control over which databases and database objects (tables, stored programs, user accounts) to dump

• Dumping of user accounts as account-management statements (CREATE USER,GRANT) rather than as inserts into themysql system database

• Capability of creating compressed output

• Progress indicator (the values are estimates)

• For dump file reloading, faster secondary index creation forInnoDB tables by adding indexes after rows are inserted

A dump made using PowerShell on Windows with output redirection creates a file that has UTF-16 encoding:

mysqlpump [options] > dump.sql

However, UTF-16 is not permitted as a connection character set (seeSection 10.4, “Connection Character Sets and Collations”), so the dump file does not load correctly. To work around this issue, use the--result-file option, which creates the output in ASCII format:

mysqlpump [options] --result-file=dump.sql

Table 4.18 mysqlpump Options

• --help,-?

  Command-Line Format	--help

  Display a help message and exit.

• --add-drop-database

  Command-Line Format	--add-drop-database

  Write aDROP DATABASE statement before eachCREATE DATABASE statement.

• --add-drop-table

  Command-Line Format	--add-drop-table

  Write aDROP TABLE statement before eachCREATE TABLE statement.

• --add-drop-user

  Command-Line Format	--add-drop-user

  Write aDROP USER statement before eachCREATE USER statement.

• --add-locks

  Command-Line Format	--add-locks

  Surround each table dump withLOCK TABLES andUNLOCK TABLES statements. This results in faster inserts when the dump file is reloaded. SeeSection 8.2.4.1, “Optimizing INSERT Statements”.

  This option does not work with parallelism becauseINSERT statements from different tables can be interleaved andUNLOCK TABLES following the end of the inserts for one table could release locks on tables for which inserts remain.

  --add-locks and--single-transaction are mutually exclusive.

• --all-databases,-A

  Command-Line Format	--all-databases

  Dump all databases (with certain exceptions noted inmysqlpump Restrictions). This is the default behavior if no other is specified explicitly.

  --all-databases and--databases are mutually exclusive.

• --bind-address=ip_address

  Command-Line Format	--bind-address=ip_address

  On a computer having multiple network interfaces, use this option to select which interface to use for connecting to the MySQL server.

• --character-sets-dir=path

  Command-Line Format	--character-sets-dir=dir_name
  Type	Directory name

  The directory where character sets are installed. SeeSection 10.15, “Character Set Configuration”.

• --complete-insert

  Command-Line Format	--complete-insert

  Write completeINSERT statements that include column names.

• --compress,-C

  Command-Line Format	--compress[={OFF|ON}]
  Type	Boolean
  Default Value	OFF

  Compress all information sent between the client and the server if possible. SeeSection 4.2.6, “Connection Compression Control”.

• --compress-output=algorithm

  Command-Line Format	--compress-output=algorithm
  Type	Enumeration
  Valid Values	LZ4 ZLIB

  By default,mysqlpump does not compress output. This option specifies output compression using the specified algorithm. Permitted algorithms areLZ4 andZLIB.

  To uncompress compressed output, you must have an appropriate utility. If the system commandslz4 andopenssl zlib are not available, as of MySQL 5.7.10, MySQL distributions includelz4_decompress andzlib_decompress utilities that can be used to decompressmysqlpump output that was compressed using the--compress-output=LZ4 and--compress-output=ZLIB options. For more information, seeSection 4.8.1, “lz4_decompress — Decompress mysqlpump LZ4-Compressed Output”, andSection 4.8.5, “zlib_decompress — Decompress mysqlpump ZLIB-Compressed Output”.

  Alternatives include thelz4 andopenssl commands, if they are installed on your system. For example,lz4 can uncompressLZ4 output:

  lz4 -dinput_file output_file

  ZLIB output can be uncompresed like this:

  openssl zlib -d <input_file >output_file

• --databases,-B

  Command-Line Format	--databases

  Normally,mysqlpump treats the first name argument on the command line as a database name and any following names as table names. With this option, it treats all name arguments as database names.CREATE DATABASE statements are included in the output before each new database.

  --all-databases and--databases are mutually exclusive.

• --debug[=debug_options],-# [debug_options]

  Command-Line Format	--debug[=debug_options]
  Type	String
  Default Value	d:t:O,/tmp/mysqlpump.trace

  Write a debugging log. A typicaldebug_options string isd:t:o,file_name. The default isd:t:O,/tmp/mysqlpump.trace.

  This option is available only if MySQL was built usingWITH_DEBUG. MySQL release binaries provided by Oracle arenot built using this option.

• --debug-check

  Command-Line Format	--debug-check
  Type	Boolean
  Default Value	FALSE

  Print some debugging information when the program exits.

  This option is available only if MySQL was built usingWITH_DEBUG. MySQL release binaries provided by Oracle arenot built using this option.

• --debug-info,-T

  Command-Line Format	--debug-info
  Type	Boolean
  Default Value	FALSE

  Print debugging information and memory and CPU usage statistics when the program exits.

  This option is available only if MySQL was built usingWITH_DEBUG. MySQL release binaries provided by Oracle arenot built using this option.

• --default-auth=plugin

  Command-Line Format	--default-auth=plugin
  Type	String

  A hint about which client-side authentication plugin to use. SeeSection 6.2.13, “Pluggable Authentication”.

• --default-character-set=charset_name

  Command-Line Format	--default-character-set=charset_name
  Type	String
  Default Value	utf8

  Usecharset_name as the default character set. SeeSection 10.15, “Character Set Configuration”. If no character set is specified,mysqlpump usesutf8.

• --default-parallelism=N

  Command-Line Format	--default-parallelism=N
  Type	Integer
  Default Value	2

  The default number of threads for each parallel processing queue. The default is 2.

  The--parallel-schemas option also affects parallelism and can be used to override the default number of threads. For more information, seemysqlpump Parallel Processing.

  With--default-parallelism=0 and no--parallel-schemas options,mysqlpump runs as a single-threaded process and creates no queues.

  With parallelism enabled, it is possible for output from different databases to be interleaved.

  Note

  Before MySQL 5.7.11, use of the--single-transaction option is mutually exclusive with parallelism. To use--single-transaction, disable parallelism by setting--default-parallelism to 0 and not using any instances of--parallel-schemas:

  mysqlpump --single-transaction --default-parallelism=0

• --defaults-extra-file=file_name

  Command-Line Format	--defaults-extra-file=file_name
  Type	File name

  Read this option file after the global option file but (on Unix) before the user option file. If the file does not exist or is otherwise inaccessible, an error occurs. Iffile_name is not an absolute path name, it is interpreted relative to the current directory.

  For additional information about this and other option-file options, seeSection 4.2.2.3, “Command-Line Options that Affect Option-File Handling”.

• --defaults-file=file_name

  Command-Line Format	--defaults-file=file_name
  Type	File name

  Use only the given option file. If the file does not exist or is otherwise inaccessible, an error occurs. Iffile_name is not an absolute path name, it is interpreted relative to the current directory.

  Exception: Even with--defaults-file, client programs read.mylogin.cnf.

  For additional information about this and other option-file options, seeSection 4.2.2.3, “Command-Line Options that Affect Option-File Handling”.

• --defaults-group-suffix=str

  Command-Line Format	--defaults-group-suffix=str
  Type	String

  Read not only the usual option groups, but also groups with the usual names and a suffix ofstr. For example,mysqlpump normally reads the[client] and[mysqlpump] groups. If this option is given as--defaults-group-suffix=_other,mysqlpump also reads the[client_other] and[mysqlpump_other] groups.

  For additional information about this and other option-file options, seeSection 4.2.2.3, “Command-Line Options that Affect Option-File Handling”.

• --defer-table-indexes

  Command-Line Format	--defer-table-indexes
  Type	Boolean
  Default Value	TRUE

  In the dump output, defer index creation for each table until after its rows have been loaded. This works for all storage engines, but forInnoDB applies only for secondary indexes.

  This option is enabled by default; use--skip-defer-table-indexes to disable it.

• --events

  Command-Line Format	--events
  Type	Boolean
  Default Value	TRUE

  Include Event Scheduler events for the dumped databases in the output. Event dumping requires theEVENT privileges for those databases.

  The output generated by using--events containsCREATE EVENT statements to create the events. However, these statements do not include attributes such as the event creation and modification timestamps, so when the events are reloaded, they are created with timestamps equal to the reload time.

  If you require events to be created with their original timestamp attributes, do not use--events. Instead, dump and reload the contents of themysql.event table directly, using a MySQL account that has appropriate privileges for themysql database.

  This option is enabled by default; use--skip-events to disable it.

• --exclude-databases=db_list

  Command-Line Format	--exclude-databases=db_list
  Type	String

  Do not dump the databases indb_list, which is a list of one or more comma-separated database names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --exclude-events=event_list

  Command-Line Format	--exclude-events=event_list
  Type	String

  Do not dump the databases inevent_list, which is a list of one or more comma-separated event names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --exclude-routines=routine_list

  Command-Line Format	--exclude-routines=routine_list
  Type	String

  Do not dump the events inroutine_list, which is a list of one or more comma-separated routine (stored procedure or function) names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --exclude-tables=table_list

  Command-Line Format	--exclude-tables=table_list
  Type	String

  Do not dump the tables intable_list, which is a list of one or more comma-separated table names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --exclude-triggers=trigger_list

  Command-Line Format	--exclude-triggers=trigger_list
  Type	String

  Do not dump the triggers intrigger_list, which is a list of one or more comma-separated trigger names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --exclude-users=user_list

  Command-Line Format	--exclude-users=user_list
  Type	String

  Do not dump the user accounts inuser_list, which is a list of one or more comma-separated account names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --extended-insert=N

  Command-Line Format	--extended-insert=N

  WriteINSERT statements using multiple-row syntax that includes severalVALUES lists. This results in a smaller dump file and speeds up inserts when the file is reloaded.

  The option value indicates the number of rows to include in eachINSERT statement. The default is 250. A value of 1 produces oneINSERT statement per table row.

• --get-server-public-key

  Command-Line Format	--get-server-public-key
  Introduced	5.7.23
  Type	Boolean

  Request from the server the public key required for RSA key pair-based password exchange. This option applies to clients that authenticate with thecaching_sha2_password authentication plugin. For that plugin, the server does not send the public key unless requested. This option is ignored for accounts that do not authenticate with that plugin. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection.

  If--server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over--get-server-public-key.

  For information about thecaching_sha2_password plugin, seeSection 6.4.1.4, “Caching SHA-2 Pluggable Authentication”.

  The--get-server-public-key option was added in MySQL 5.7.23.

• --hex-blob

  Command-Line Format	--hex-blob

  Dump binary columns using hexadecimal notation (for example,'abc' becomes0x616263). The affected data types areBINARY,VARBINARY,BLOB types,BIT, all spatial data types, and other non-binary data types when used with thebinary character set.

• --host=host_name,-hhost_name

  Command-Line Format	--host

  Dump data from the MySQL server on the given host.

• --include-databases=db_list

  Command-Line Format	--include-databases=db_list
  Type	String

  Dump the databases indb_list, which is a list of one or more comma-separated database names. The dump includes all objects in the named databases. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --include-events=event_list

  Command-Line Format	--include-events=event_list
  Type	String

  Dump the events inevent_list, which is a list of one or more comma-separated event names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --include-routines=routine_list

  Command-Line Format	--include-routines=routine_list
  Type	String

  Dump the routines inroutine_list, which is a list of one or more comma-separated routine (stored procedure or function) names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --include-tables=table_list

  Command-Line Format	--include-tables=table_list
  Type	String

  Dump the tables intable_list, which is a list of one or more comma-separated table names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --include-triggers=trigger_list

  Command-Line Format	--include-triggers=trigger_list
  Type	String

  Dump the triggers intrigger_list, which is a list of one or more comma-separated trigger names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --include-users=user_list

  Command-Line Format	--include-users=user_list
  Type	String

  Dump the user accounts inuser_list, which is a list of one or more comma-separated user names. Multiple instances of this option are additive. For more information, seemysqlpump Object Selection.

• --insert-ignore

  Command-Line Format	--insert-ignore

  WriteINSERT IGNORE statements rather thanINSERT statements.

• --log-error-file=file_name

  Command-Line Format	--log-error-file=file_name
  Type	File name

  Log warnings and errors by appending them to the named file. If this option is not given,mysqlpump writes warnings and errors to the standard error output.

• --login-path=name

  Command-Line Format	--login-path=name
  Type	String

  Read options from the named login path in the.mylogin.cnf login path file. A“login path” is an option group containing options that specify which MySQL server to connect to and which account to authenticate as. To create or modify a login path file, use themysql_config_editor utility. SeeSection 4.6.6, “mysql_config_editor — MySQL Configuration Utility”.

  For additional information about this and other option-file options, seeSection 4.2.2.3, “Command-Line Options that Affect Option-File Handling”.

• --max-allowed-packet=N

  Command-Line Format	--max-allowed-packet=N
  Type	Numeric
  Default Value	25165824

  The maximum size of the buffer for client/server communication. The default is 24MB, the maximum is 1GB.

• --net-buffer-length=N

  Command-Line Format	--net-buffer-length=N
  Type	Numeric
  Default Value	1047552

  The initial size of the buffer for client/server communication. When creating multiple-rowINSERT statements (as with the--extended-insert option),mysqlpump creates rows up toN bytes long. If you use this option to increase the value, ensure that the MySQL servernet_buffer_length system variable has a value at least this large.

• --no-create-db

  Command-Line Format	--no-create-db

  Suppress anyCREATE DATABASE statements that might otherwise be included in the output.

• --no-create-info,-t

  Command-Line Format	--no-create-info

  Do not writeCREATE TABLE statements that create each dumped table.

• --no-defaults

  Command-Line Format	--no-defaults

  Do not read any option files. If program startup fails due to reading unknown options from an option file,--no-defaults can be used to prevent them from being read.

  The exception is that the.mylogin.cnf file is read in all cases, if it exists. This permits passwords to be specified in a safer way than on the command line even when--no-defaults is used. To create.mylogin.cnf, use themysql_config_editor utility. SeeSection 4.6.6, “mysql_config_editor — MySQL Configuration Utility”.

  For additional information about this and other option-file options, seeSection 4.2.2.3, “Command-Line Options that Affect Option-File Handling”.

• --parallel-schemas=[N:]db_list

  Command-Line Format	--parallel-schemas=[N:]schema_list
  Type	String

  Create a queue for processing the databases indb_list, which is a list of one or more comma-separated database names. IfN is given, the queue usesN threads. IfN is not given, the--default-parallelism option determines the number of queue threads.

  Multiple instances of this option create multiple queues.mysqlpump also creates a default queue to use for databases not named in any--parallel-schemas option, and for dumping user definitions if command options select them. For more information, seemysqlpump Parallel Processing.

• --password[=password],-p[password]

  Command-Line Format	--password[=password]
  Type	String

  The password of the MySQL account used for connecting to the server. The password value is optional. If not given,mysqlpump prompts for one. If given, there must beno space between--password= or-p and the password following it. If no password option is specified, the default is to send no password.

  Specifying a password on the command line should be considered insecure. To avoid giving the password on the command line, use an option file. SeeSection 6.1.2.1, “End-User Guidelines for Password Security”.

  To explicitly specify that there is no password and thatmysqlpump should not prompt for one, use the--skip-password option.

• --plugin-dir=dir_name

  Command-Line Format	--plugin-dir=dir_name
  Type	Directory name

  The directory in which to look for plugins. Specify this option if the--default-auth option is used to specify an authentication plugin butmysqlpump does not find it. SeeSection 6.2.13, “Pluggable Authentication”.

• --port=port_num,-Pport_num

  Command-Line Format	--port=port_num
  Type	Numeric
  Default Value	3306

  For TCP/IP connections, the port number to use.

• --print-defaults

  Command-Line Format	--print-defaults

  Print the program name and all options that it gets from option files.

  For additional information about this and other option-file options, seeSection 4.2.2.3, “Command-Line Options that Affect Option-File Handling”.

• --protocol={TCP|SOCKET|PIPE|MEMORY}

  Command-Line Format	--protocol=type
  Type	String
  Default Value	[see text]
  Valid Values	TCP SOCKET PIPE MEMORY

  The transport protocol to use for connecting to the server. It is useful when the other connection parameters normally result in use of a protocol other than the one you want. For details on the permissible values, seeSection 4.2.5, “Connection Transport Protocols”.

• --replace

  Command-Line Format	--replace

  WriteREPLACE statements rather thanINSERT statements.

• --result-file=file_name

  Command-Line Format	--result-file=file_name
  Type	File name

  Direct output to the named file. The result file is created and its previous contents overwritten, even if an error occurs while generating the dump.

  This option should be used on Windows to prevent newline\n characters from being converted to\r\n carriage return/newline sequences.

• --routines

  Command-Line Format	--routines
  Type	Boolean
  Default Value	TRUE

  Include stored routines (procedures and functions) for the dumped databases in the output. This option requires theSELECT privilege for themysql.proc table.

  The output generated by using--routines containsCREATE PROCEDURE andCREATE FUNCTION statements to create the routines. However, these statements do not include attributes such as the routine creation and modification timestamps, so when the routines are reloaded, they are created with timestamps equal to the reload time.

  If you require routines to be created with their original timestamp attributes, do not use--routines. Instead, dump and reload the contents of themysql.proc table directly, using a MySQL account that has appropriate privileges for themysql database.

  This option is enabled by default; use--skip-routines to disable it.

• --secure-auth

  Command-Line Format	--secure-auth

  Do not send passwords to the server in old (pre-4.1) format. This prevents connections except for servers that use the newer password format.

  This option is deprecated; expect it to be removed in a future MySQL release. It is always enabled and attempting to disable it (--skip-secure-auth,--secure-auth=0) produces an error.

• --server-public-key-path=file_name

  Command-Line Format	--server-public-key-path=file_name
  Introduced	5.7.23
  Type	File name

  The path name to a file in PEM format containing a client-side copy of the public key required by the server for RSA key pair-based password exchange. This option applies to clients that authenticate with thesha256_password orcaching_sha2_password authentication plugin. This option is ignored for accounts that do not authenticate with one of those plugins. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection.

  If--server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over--get-server-public-key.

  Forsha256_password, this option applies only if MySQL was built using OpenSSL.

  For information about thesha256_password andcaching_sha2_password plugins, seeSection 6.4.1.5, “SHA-256 Pluggable Authentication”, andSection 6.4.1.4, “Caching SHA-2 Pluggable Authentication”.

  The--server-public-key-path option was added in MySQL 5.7.23.

• --set-charset

  Command-Line Format	--set-charset

  WriteSET NAMESdefault_character_set to the output.

  This option is enabled by default. To disable it and suppress theSET NAMES statement, use--skip-set-charset.

• --set-gtid-purged=value

  Command-Line Format	--set-gtid-purged=value
  Introduced	5.7.18
  Type	Enumeration
  Default Value	AUTO
  Valid Values	OFF ON AUTO

  This option enables control over global transaction ID (GTID) information written to the dump file, by indicating whether to add aSET @@GLOBAL.gtid_purged statement to the output. This option may also cause a statement to be written to the output that disables binary logging while the dump file is being reloaded.

  The following table shows the permitted option values. The default value isAUTO.

  Value	Meaning
  OFF	Add noSET statement to the output.
  ON	Add aSET statement to the output. An error occurs if GTIDs are not enabled on the server.
  AUTO	Add aSET statement to the output if GTIDs are enabled on the server.

  The--set-gtid-purged option has the following effect on binary logging when the dump file is reloaded:

  • --set-gtid-purged=OFF:SET @@SESSION.SQL_LOG_BIN=0; is not added to the output.

  • --set-gtid-purged=ON:SET @@SESSION.SQL_LOG_BIN=0; is added to the output.

  • --set-gtid-purged=AUTO:SET @@SESSION.SQL_LOG_BIN=0; is added to the output if GTIDs are enabled on the server you are backing up (that is, ifAUTO evaluates toON).

  This option was added in MySQL 5.7.18.

• --single-transaction

  Command-Line Format	--single-transaction

  This option sets the transaction isolation mode toREPEATABLE READ and sends aSTART TRANSACTION SQL statement to the server before dumping data. It is useful only with transactional tables such asInnoDB, because then it dumps the consistent state of the database at the time whenSTART TRANSACTION was issued without blocking any applications.

  When using this option, you should keep in mind that onlyInnoDB tables are dumped in a consistent state. For example, anyMyISAM orMEMORY tables dumped while using this option may still change state.

  While a--single-transaction dump is in process, to ensure a valid dump file (correct table contents and binary log coordinates), no other connection should use the following statements:ALTER TABLE,CREATE TABLE,DROP TABLE,RENAME TABLE,TRUNCATE TABLE. A consistent read is not isolated from those statements, so use of them on a table to be dumped can cause theSELECT that is performed bymysqlpump to retrieve the table contents to obtain incorrect contents or fail.

  --add-locks and--single-transaction are mutually exclusive.

  Note

  Before MySQL 5.7.11, use of the--single-transaction option is mutually exclusive with parallelism. To use--single-transaction, disable parallelism by setting--default-parallelism to 0 and not using any instances of--parallel-schemas:

  mysqlpump --single-transaction --default-parallelism=0

• --skip-definer

  Command-Line Format	--skip-definer
  Type	Boolean
  Default Value	FALSE

  OmitDEFINER andSQL SECURITY clauses from theCREATE statements for views and stored programs. The dump file, when reloaded, creates objects that use the defaultDEFINER andSQL SECURITY values. SeeSection 23.6, “Stored Object Access Control”.

• --skip-dump-rows,-d

  Command-Line Format	--skip-dump-rows
  Type	Boolean
  Default Value	FALSE

  Do not dump table rows.

• --socket=path,-Spath

  Command-Line Format	--socket={file_name|pipe_name}
  Type	String

  For connections tolocalhost, the Unix socket file to use, or, on Windows, the name of the named pipe to use.

  On Windows, this option applies only if the server was started with thenamed_pipe system variable enabled to support named-pipe connections. In addition, the user making the connection must be a member of the Windows group specified by thenamed_pipe_full_access_group system variable.

• --ssl*

  Options that begin with--ssl specify whether to connect to the server using encryption and indicate where to find SSL keys and certificates. SeeCommand Options for Encrypted Connections.

• --tls-version=protocol_list

  Command-Line Format	--tls-version=protocol_list
  Introduced	5.7.10
  Type	String
  Default Value (≥ 5.7.28)	TLSv1,TLSv1.1,TLSv1.2
  Default Value (≤ 5.7.27)	TLSv1,TLSv1.1,TLSv1.2 (OpenSSL) TLSv1,TLSv1.1 (yaSSL)

  The permissible TLS protocols for encrypted connections. The value is a list of one or more comma-separated protocol names. The protocols that can be named for this option depend on the SSL library used to compile MySQL. For details, seeSection 6.3.2, “Encrypted Connection TLS Protocols and Ciphers”.

  This option was added in MySQL 5.7.10.

• --triggers

  Command-Line Format	--triggers
  Type	Boolean
  Default Value	TRUE

  Include triggers for each dumped table in the output.

  This option is enabled by default; use--skip-triggers to disable it.

• --tz-utc

  Command-Line Format	--tz-utc

  This option enablesTIMESTAMP columns to be dumped and reloaded between servers in different time zones.mysqlpump sets its connection time zone to UTC and addsSET TIME_ZONE='+00:00' to the dump file. Without this option,TIMESTAMP columns are dumped and reloaded in the time zones local to the source and destination servers, which can cause the values to change if the servers are in different time zones.--tz-utc also protects against changes due to daylight saving time.

  This option is enabled by default; use--skip-tz-utc to disable it.

• --user=user_name,-uuser_name

  Command-Line Format	--user=user_name
  Type	String

  The user name of the MySQL account to use for connecting to the server.

• --users

  Command-Line Format	--users
  Type	Boolean
  Default Value	FALSE

  Dump user accounts as logical definitions in the form ofCREATE USER andGRANT statements.

  User definitions are stored in the grant tables in themysql system database. By default,mysqlpump does not include the grant tables inmysql database dumps. To dump the contents of the grant tables as logical definitions, use the--users option and suppress all database dumping:

  mysqlpump --exclude-databases=% --users

• --version,-V

  Command-Line Format	--version

  Display version information and exit.

• --watch-progress

  Command-Line Format	--watch-progress
  Type	Boolean
  Default Value	TRUE

  Periodically display a progress indicator that provides information about the completed and total number of tables, rows, and other objects.

  This option is enabled by default; use--skip-watch-progress to disable it.

• --include-databases and--exclude-databases apply to databases and all objects within them.

• --include-tables and--exclude-tables apply to tables. These options also affect triggers associated with tables unless the trigger-specific options are given.

• --include-triggers and--exclude-triggers apply to triggers.

• --include-routines and--exclude-routines apply to stored procedures and functions. If a routine option matches a stored procedure name, it also matches a stored function of the same name.

• --include-events and--exclude-events apply to Event Scheduler events.

• --include-users and--exclude-users apply to user accounts.

• % matches any sequence of zero or more characters.

• _ matches any single character.

• By default, with no inclusion or exclusion options,mysqlpump dumps all databases (with certain exceptions noted inmysqlpump Restrictions).

• If inclusion options are given in the absence of exclusion options, only the objects named as included are dumped.

• If exclusion options are given in the absence of inclusion options, all objects are dumped except those named as excluded.

• If inclusion and exclusion options are given, all objects named as excluded and not named as included are not dumped. All other objects are dumped.

• The--all-databases option dumps all databases (with certain exceptions noted inmysqlpump Restrictions). It is equivalent to specifying no object options at all (the defaultmysqlpump action is to dump everything).

  --include-databases=% is similar to--all-databases, but selects all databases for dumping, even those that are exceptions for--all-databases.

• The--databases option causesmysqlpump to treat all name arguments as names of databases to dump. It is equivalent to an--include-databases option that names the same databases.

• --default-parallelism=N specifies the default number of threads used for each queue. In the absence of this option,N is 2.

  The default queue always uses the default number of threads. Additional queues use the default number of threads unless you specify otherwise.

• --parallel-schemas=[N:]db_list sets up a processing queue for dumping the databases named indb_list and optionally specifies how many threads the queue uses.db_list is a list of comma-separated database names. If the option argument begins withN:, the queue usesN threads. Otherwise, the--default-parallelism option determines the number of queue threads.

  Multiple instances of the--parallel-schemas option create multiple queues.

  Names in the database list are permitted to contain the same% and_ wildcard characters supported for filtering options (seemysqlpump Object Selection).

Before MySQL 5.7.11, use of the--single-transaction option is mutually exclusive with parallelism. To use--single-transaction, disable parallelism by setting--default-parallelism to 0 and not using any instances of--parallel-schemas:

mysqlpump --single-transaction --default-parallelism=0
