updateStreamWarmThroughput

Updates the warm throughput configuration for the specified Amazon Kinesis Data Streams on-demand data stream. This operation allows you to proactively scale your on-demand data stream to a specified throughput level, enabling better performance for sudden traffic spikes.

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.

Updating the warm throughput is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns immediately and sets the status of the stream to UPDATING. After the update is complete, Kinesis Data Streams sets the status of the stream back to ACTIVE. Depending on the size of the stream, the scaling action could take a few minutes to complete. You can continue to read and write data to your stream while its status is UPDATING.

This operation is only supported for data streams with the on-demand capacity mode in accounts that have MinimumThroughputBillingCommitment enabled. Provisioned capacity mode streams do not support warm throughput configuration.

This operation has the following default limits. By default, you cannot do the following:

• Scale to more than 10 GiBps for an on-demand stream.

• This API has a call limit of 5 transactions per second (TPS) for each Amazon Web Services account. TPS over 5 will initiate the LimitExceededException.

For the default limits for an Amazon Web Services account, see Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To request an increase in the call rate limit, the shard limit for this API, or your overall shard limit, use the limits form.
