create_global_table¶

create_global_table(**kwargs)¶

Creates a global table from an existing table. A global table creates a replication relationship between two or more DynamoDB tables with the same table name in the provided Regions.

Note

This operation only applies to Version 2017.11.29 of global tables.

If you want to add a new replica table to a global table, each of the following conditions must be true:

The table must have the same primary key as all of the other replicas.
The table must have the same name as all of the other replicas.
The table must have DynamoDB Streams enabled, with the stream containing both the new and the old images of the item.
None of the replica tables in the global table can contain any data.

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).

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

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

Warning

Write capacity settings should be set consistently across your replica tables and secondary indexes. DynamoDB strongly recommends enabling auto scaling to manage the write capacity settings for all of your global tables replicas and indexes.

If you prefer to manage write capacity settings manually, you should provision equal replicated write capacity units to your replica tables. You should also provision equal replicated write capacity units to matching secondary indexes across your global table.

Response Structure

(dict) --
- GlobalTableDescription (dict) --
  
  Contains the details of the global table.
  - ReplicationGroup (list) --
    
    The Regions where the global table has replicas.
    - (dict) --
      
      Contains the details of the replica.
      - RegionName (string) --
        
        The name of the Region.
      - ReplicaStatus (string) --
        
        The current state of the replica:
        
        CREATING - The replica is being created.
        
        UPDATING - The replica is being updated.
        
        DELETING - The replica is being deleted.
        
        ACTIVE - The replica is ready for use.
        
        REGION_DISABLED - The replica is inaccessible because the Amazon Web Services Region has been disabled.
        
        Note
        
        If the Amazon Web Services Region remains inaccessible for more than 20 hours, DynamoDB will remove this replica from the replication group. The replica will not be deleted and replication will stop from and to this region.
        
        INACCESSIBLE_ENCRYPTION_CREDENTIALS - The KMS key used to encrypt the table is inaccessible.
        
        Note
        
        If the KMS key remains inaccessible for more than 20 hours, DynamoDB will remove this replica from the replication group. The replica will not be deleted and replication will stop from and to this region.
