• credentials - (String, Hash, Google::Auth::Credentials) The path tothe keyfile as a String, the contents of the keyfile as a Hash, or aGoogle::Auth::Credentials object. (SeeCredentials) (Theparameterkeyfile is considered deprecated, but may also be used.)
• scope - (String, Array
• quota_project - (String) The project ID for a project that can beused by client libraries for quota and billing purposes.
• timeout - (Integer) Default timeout to use in requests.
• endpoint - (String) Override of the endpoint host name, ornilto use the default endpoint.
• emulator_host - (String) Host name of the emulator. Defaults toENV["SPANNER_EMULATOR_HOST"].
• lib_name - (String) Override the lib name , ornilto use the default lib name without prefix in agent trackingheader.
• lib_version - (String) Override the lib version , ornilto use the default version lib name without prefix in agenttracking header.

• (Google::Cloud::Config) — The configuration object theGoogle::Cloud::Spanner library uses.

Creates a new object for connecting to the Spanner service.Each call creates a new connection.

For more information on connecting to Google Cloud see theAuthentication Guide.

• project_id (String)(defaults to: nil) — Project identifier for the Spanner serviceyou are connecting to. If not present, the default project for thecredentials is used.
• credentials (String, Hash, Google::Auth::Credentials)(defaults to: nil) — The path tothe keyfile as a String, the contents of the keyfile as a Hash, or aGoogle::Auth::Credentials object. (SeeCredentials)Ifemulator_host is present, this becomes optional and the value isinternally overriden with:this_channel_is_insecure.
• scope (String, Array<String>)(defaults to: nil) —

  The OAuth 2.0 scopes controllingthe set of resources and operations that the connection can access.SeeUsing OAuth 2.0 to Access GoogleAPIs.

  The default scopes are:

  • https://www.googleapis.com/auth/spanner
  • https://www.googleapis.com/auth/spanner.data
• timeout (Integer)(defaults to: nil) — Default timeout to use in requests. Optional.
• endpoint (String)(defaults to: nil) — Override of the endpoint host name. Optional.If the param is nil, usesemulator_host or the default endpoint.
• project (String)(defaults to: nil) — Alias for theproject_id argument. Deprecated.
• keyfile (String)(defaults to: nil) — Alias for thecredentials argument.Deprecated.
• emulator_host (String)(defaults to: nil) — Spanner emulator host. Optional.If the param is nil, uses the value of theemulator_host config.
• lib_name (String)(defaults to: nil) — Library name. This will be added as a prefixto the API call tracking headerx-goog-api-client with providedlib version for telemetry. Optional. For example prefix looks likespanner-activerecord/0.0.1 gccl/1.13.1. Here,spanner-activerecord/0.0.1 is provided custom library name andversion andgccl/1.13.1 represents the Cloud Spanner Ruby librarywith version.
• lib_version (String)(defaults to: nil) — Library version. This will be added as aprefix to the API call tracking headerx-goog-api-client withprovided lib name for telemetry. Optional. For example prefix look likespanner-activerecord/0.0.1 gccl/1.13.1. Here,spanner-activerecord/0.0.1 is provided custom library name andversion andgccl/1.13.1 represents the Cloud Spanner Ruby librarywith version.
