Update Global Table

dynamodb_update_global_table

R Documentation

Adds or removes replicas in the specified global table

Description

Adds or removes replicas in the specified global table. The global table must already exist to be able to use this operation. Any replica to be added must be empty, have the same name as the global table, have the same key schema, have DynamoDB Streams enabled, and have the same provisioned and maximum write capacity units.

This documentation is for version 2017.11.29 (Legacy) of global tables, which should be avoided for new global tables. Customers should use Global Tables version 2019.11.21 (Current) when possible, because it provides greater flexibility, higher efficiency, and consumes less write capacity than 2017.11.29 (Legacy).

To determine which version you're using, see Determining the global table version you are using. To update existing global tables from version 2017.11.29 (Legacy) to version 2019.11.21 (Current), see Upgrading global tables.

For global tables, this operation only applies to global tables using Version 2019.11.21 (Current version). If you are using global tables Version 2019.11.21 you can use update_table instead.

Although you can use update_global_table to add replicas and remove replicas in a single request, for simplicity we recommend that you issue separate requests for adding or removing replicas.

If global secondary indexes are specified, then the following conditions must also be met:

• The global secondary indexes must have the same name.

• The global secondary indexes must have the same hash key and sort key (if present).

• The global secondary indexes must have the same provisioned and maximum write capacity units.
