Create a new table with client-side timestamps in Amazon Keyspaces

Sign in to the Amazon Web Services Management Console, and open the Amazon Keyspaces console at https://console.amazonaws.cn/keyspaces/home.

In the navigation pane, choose Tables, and then choose Create table.

On the Create table page in the Table details section, select a keyspace and provide a name for the new table.

In the Schema section, create the schema for your table.

In the Table settings section, choose Customize settings.

Continue to Client-side timestamps.

Choose Turn on client-side timestamps to turn on client-side timestamps for the table.

Choose Create table. Your table is created with client-side timestamps turned on.

To create a new table with client-side timestamps enabled using CQL, you can use the following example.

CREATE TABLE my_keyspace.my_table (
   userid uuid,
   time timeuuid,
   subject text,
   body text,
   user inet,
   PRIMARY KEY (userid, time)
) WITH CUSTOM_PROPERTIES = {'client_side_timestamps': {'status': 'enabled'}};

To confirm the client-side timestamps settings for the new table, use a SELECT statement to review the custom_properties as shown in the following example.

SELECT custom_properties from system_schema_mcs.tables where keyspace_name = 'my_keyspace' and table_name = 'my_table';

The output of this statement shows the status for client-side timestamps.

'client_side_timestamps': {'status': 'enabled'}

To create a new table with client-side timestamps enabled, you can use the following example.

./aws keyspaces create-table \
--keyspace-name my_keyspace \
--table-name my_table \
--client-side-timestamps 'status=ENABLED' \
--schema-definition 'allColumns=[{name=id,type=int},{name=date,type=timestamp},{name=name,type=text}],partitionKeys=[{name=id}]'

To confirm that client-side timestamps are turned on for the new table, run the following code.

./aws keyspaces get-table \
--keyspace-name my_keyspace \
--table-name my_table 

The output should look similar to this example.
