-----------------------------------
Summary: Add polling interval to KinesisIO.Read
Key: BEAM-8382
URL: https://issues.apache.org/jira/browse/BEAM-8382
Project: Beam
Issue Type: Improvement
Components: io-java-kinesis
Affects Versions: 2.15.0, 2.14.0, 2.13.0
Reporter: Jonothan Farr
Assignee: Jonothan Farr
With the current implementation we are observing Kinesis throttling due to
ReadProvisionedThroughputExceeded on the order of hundreds of times per second,
regardless of the actual Kinesis throughput. This is because the
ShardReadersPool readLoop() method is polling getRecords() as fast as possible.
>From the KDS documentation:
{quote}Each shard can support up to five read transactions per second.
{quote}
and
{quote}For best results, sleep for at least 1 second (1,000 milliseconds)
between calls to getRecords to avoid exceeding the limit on getRecords
frequency.
