View the tags of a stream

The following examples show how to view the tags of a stream in Amazon Keyspaces using CQL or the Amazon CLI.

Cassandra Query Language (CQL)
View the tags of a stream using CQL

To read the tags attached to a stream, you must specify the resource ARN of the stream in the WHERE clause. The following CQL syntax is an example of this.

SELECT * FROM system_schema_mcs.tags WHERE resource_id = stream_arn;

  • The following query returns the tags for the specified stream.

    SELECT tags FROM system_schema_mcs.tags WHERE resource_id = 'arn:aws-cn:cassandra:aws-region:111122223333:/keyspace/my_keyspace/table/my_table/stream/2025-05-06T17:17:39.800';

    The output of that query looks like the following.

     resource_id                                                                                                       | keyspace_name | resource_name           | resource_type | tags   
 ------------------------------------------------------------------------------------------------------------------+---------------+-------------------------+---------------+---------------------- 
 arn:aws-cn:cassandra:aws-region:111122223333:/keyspace/my_keyspace/table/my_table/stream/2025-04-02T23:00:07.052     |      singleks | 2025-04-02T23:00:07.052 |        stream | {'tagkey': 'tagval'}
CLI
View the tags of a stream using the Amazon CLI

  • This example shows how to list the tags for all streams under the specified keyspace.

    aws keyspaces list-tags-for-resource --resource-arn 'arn:aws-cn:cassandra:aws-region:111122223333:/keyspace/my_keyspace/table/my_table/stream/2025-05-11T21:21:33.291'

    The output of the last command looks like this.

    {
    "tags": [
        {
            "key": "key1",
            "value": "val1"
        },
        {
            "key": "key2",
            "value": "val2"
        },
        {
            "key": "key3",
            "value": "val3"
        },
        {
            "key": "key4",
            "value": "val4"
        }
    ]
}
