Keyspaces / Client / create_table

create_table#

Keyspaces.Client.create_table(**kwargs)#

The CreateTable operation adds a new table to the specified keyspace. Within a keyspace, table names must be unique.

CreateTable is an asynchronous operation. When the request is received, the status of the table is set to CREATING. You can monitor the creation status of the new table by using the GetTable operation, which returns the current status of the table. You can start using a table when the status is ACTIVE.

For more information, see Creating tables in the Amazon Keyspaces Developer Guide.
