Terraform module to create a DynamoDB table.

module"dynamodb_table" {source="terraform-aws-modules/dynamodb-table/aws"name="my-table"hash_key="id"attributes=[    {      name="id"      type="N"    }  ]tags={    Terraform="true"    Environment="staging"  }}

Warning: enabling or disabling autoscaling can cause your table to be recreated

There are two separate Terraform resources used for the DynamoDB table: one is for when any autoscaling is enabled the other when disabled. If your table is already created and then you change the variableautoscaling_enabled then your table will be recreated by Terraform. In this case you will need to move the oldaws_dynamodb_table resource that is beingdestroyed to the new resource that is beingcreated. For example:

terraform state mv module.dynamodb_table.aws_dynamodb_table.this module.dynamodb_table.aws_dynamodb_table.autoscaled

Warning: autoscaling with global secondary indexes

When using an autoscaled provisioned table with GSIs you may find that applying TF changes whilst a GSI is scaled up will reset the capacity, thereis anopen issue for this on the AWS Provider. To get around this issue you can enabletheignore_changes_global_secondary_index setting however, using this setting means that any changes to GSIs will be ignored by Terraform and willhence have to be applied manually (or via some other automation).

NOTE: Settingignore_changes_global_secondary_index after the table is already created causes your table to be recreated. In this case, you willneed to move the oldaws_dynamodb_table resource that is beingdestroyed to the new resource that is beingcreated. For example:

terraform state mv module.dynamodb_table.aws_dynamodb_table.autoscaled module.dynamodb_table.aws_dynamodb_table.autoscaled_ignore_gsi

Users of this Terraform module can create multiple similar resources by usingfor_each meta-argument withinmodule block which became available in Terraform 0.13.

Users of Terragrunt can achieve similar results by using modules provided in thewrappers directory, if they prefer to reduce amount of configuration files.
