Amazon Kinesis

2025/11/03 - Amazon Kinesis - 3 new3 updated api methods

Changes  Adds support for MinimumThroughputBillingCommitment with new UpdateAccountSettings API. Adds support to configure warm throughput for on-demand streams in new UpdateStreamWarmThroughput API and existing CreateStream API and UpdateStreamMode API.

DescribeAccountSettings (new) Link ¶

Describes the account-level settings for Amazon Kinesis Data Streams. This operation returns information about the minimum throughput billing commitments and other account-level configurations.

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.

    'MinimumThroughputBillingCommitment': {
        'Status': 'ENABLED'|'DISABLED'|'ENABLED_UNTIL_EARLIEST_ALLOWED_END',

        'EndedAt': datetime(2015, 1, 1),
        'EarliestAllowedEndAt': datetime(2015, 1, 1)
    }
}

Response Structure

  • (dict) --

    • MinimumThroughputBillingCommitment (dict) --

      The current configuration of the minimum throughput billing commitment for your Amazon Web Services account.

      • Status (string) --

        The current status of the minimum throughput billing commitment.

      • StartedAt (datetime) --

        The timestamp when the commitment was started.

      • EndedAt (datetime) --

        The timestamp when the commitment was ended.

      • EarliestAllowedEndAt (datetime) --

        The earliest timestamp when the commitment can be ended.

UpdateStreamWarmThroughput (new) Link ¶

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.

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.

CreateStream (updated) Link ¶
Changes (request)
{'WarmThroughputMiBps': 'integer'}

Creates a Kinesis data stream. A stream captures and transports data records that are continuously emitted from different data sources or producers. Scale-out within a stream is explicitly supported by means of shards, which are uniquely identified groups of data records in a stream.

You can create your data stream using either on-demand or provisioned capacity mode. Data streams with an on-demand mode require no capacity planning and automatically scale to handle gigabytes of write and read throughput per minute. With the on-demand mode, Kinesis Data Streams automatically manages the shards in order to provide the necessary throughput.

If you'd still like to proactively scale your on-demand data stream’s capacity, you can unlock the warm throughput feature for on-demand data streams by enabling MinimumThroughputBillingCommitment for your account. Once your account has MinimumThroughputBillingCommitment enabled, you can specify the warm throughput in MiB per second that your stream can support in writes.

For the data streams with a provisioned mode, you must specify the number of shards for the data stream. Each shard can support reads up to five transactions per second, up to a maximum data read total of 2 MiB per second. Each shard can support writes up to 1,000 records per second, up to a maximum data write total of 1 MiB per second. If the amount of data input increases or decreases, you can add or remove shards.

The stream name identifies the stream. The name is scoped to the Amazon Web Services account used by the application. It is also scoped by Amazon Web Services Region. That is, two streams in two different accounts can have the same name, and two streams in the same account, but in two different Regions, can have the same name.

CreateStream is an asynchronous operation. Upon receiving a CreateStream request, Kinesis Data Streams immediately returns and sets the stream status to CREATING. After the stream is created, Kinesis Data Streams sets the stream status to ACTIVE. You should perform read and write operations only on an ACTIVE stream.

You receive a LimitExceededException when making a CreateStream request when you try to do one of the following:

  • Have more than five streams in the CREATING state at any point in time.

  • Create more shards than are authorized for your account.

For the default shard or on-demand throughput limits for an Amazon Web Services account, see Amazon Kinesis Data Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact Amazon Web Services Support.

You can use DescribeStreamSummary to check the stream status, which is returned in StreamStatus.

CreateStream has a limit of five transactions per second per account.

You can add tags to the stream when making a CreateStream request by setting the Tags parameter. If you pass the Tags parameter, in addition to having the kinesis:CreateStream permission, you must also have the kinesis:AddTagsToStream permission for the stream that will be created. The kinesis:TagResource permission won’t work to tag streams on creation. Tags will take effect from the CREATING status of the stream, but you can't make any updates to the tags until the stream is in ACTIVE state.
