Kinesis / Client / describe_stream_summary



Provides a summarized description of the specified Kinesis data stream without the shard list.


When invoking this API, you must use either the StreamARN or the StreamName parameter, or both. It is recommended that you use the StreamARN input parameter when you invoke this API.

The information returned includes the stream name, Amazon Resource Name (ARN), status, record retention period, approximate creation time, monitoring, encryption details, and open shard count.

DescribeStreamSummary has a limit of 20 transactions per second per account.

Response Structure

  • (dict) –

    • StreamDescriptionSummary (dict) –

      A StreamDescriptionSummary containing information about the stream.

      • StreamName (string) –

        The name of the stream being described.

      • StreamARN (string) –

        The Amazon Resource Name (ARN) for the stream being described.

      • StreamStatus (string) –

        The current status of the stream being described. The stream status is one of the following states:

        • CREATING - The stream is being created. Kinesis Data Streams immediately returns and sets StreamStatus to CREATING.

        • DELETING - The stream is being deleted. The specified stream is in the DELETING state until Kinesis Data Streams completes the deletion.

        • ACTIVE - The stream exists and is ready for read and write operations or deletion. You should perform read and write operations only on an ACTIVE stream.

        • UPDATING - Shards in the stream are being merged or split. Read and write operations continue to work while the stream is in the UPDATING state.

      • StreamModeDetails (dict) –

        Specifies the capacity mode to which you want to set your data stream. Currently, in Kinesis Data Streams, you can choose between an on-demand ycapacity mode and a provisioned capacity mode for your data streams.

        • StreamMode (string) –

          Specifies the capacity mode to which you want to set your data stream. Currently, in Kinesis Data Streams, you can choose between an on-demand capacity mode and a provisioned capacity mode for your data streams.

      • RetentionPeriodHours (integer) –

        The current retention period, in hours.

      • StreamCreationTimestamp (datetime) –

        The approximate time that the stream was created.

      • EnhancedMonitoring (list) –

        Represents the current enhanced monitoring settings of the stream.

        • (dict) –

          Represents enhanced metrics types.

          • ShardLevelMetrics (list) –

            List of shard-level metrics.

            The following are the valid shard-level metrics. The value “ ALL” enhances every metric.

            • IncomingBytes

            • IncomingRecords

            • OutgoingBytes

            • OutgoingRecords

            • WriteProvisionedThroughputExceeded

            • ReadProvisionedThroughputExceeded

            • IteratorAgeMilliseconds

            • ALL

            • (string) –

      • EncryptionType (string) –

        The encryption type used. This value is one of the following:

        • KMS

        • NONE

      • KeyId (string) –

        The GUID for the customer-managed Amazon Web Services KMS key to use for encryption. This value can be a globally unique identifier, a fully specified ARN to either an alias or a key, or an alias name prefixed by “alias/”.You can also use a master key owned by Kinesis Data Streams by specifying the alias aws/kinesis.

        • Key ARN example: arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012

        • Alias ARN example: arn:aws:kms:us-east-1:123456789012:alias/MyAliasName

        • Globally unique key ID example: 12345678-1234-1234-1234-123456789012

        • Alias name example: alias/MyAliasName

        • Master key owned by Kinesis Data Streams: alias/aws/kinesis

      • OpenShardCount (integer) –

        The number of open shards in the stream.

      • ConsumerCount (integer) –

        The number of enhanced fan-out consumers registered with the stream.
