We are excited to announce the new ListShards API which makes it easier for your Kinesis Data Streams KCL applications to scale. Many Kinesis Data Streams customers use the KCL to process records from their data streams. Starting in version 1.9.0 or later, key KCL API functions now use the ListShards API, which supports a 10x higher call rate limit compared to the DescribeStream API, which was used for these functions in earlier KCL versions.
