Re: RateLimit for Kinesis Producer


Are you sure rate limit is coming from KinesisProducer?
If yes, Kinesis support 1000 record write per sec per shard. if you hit the limit, just increase your shard.

Hi all,

we are struggling with RateLimitExceededExceptions with the Kinesis
Producer. The Flink documentation claims that the Flink Producer
overrides the RateLimit setting from Amazon's default of 150 to 100.

I am wondering whether we'd need 100/($sink_parallelism) in order for it
to work correctly. Since the shard partitioner works on a provided key,
every parallel flink sink may use all the shards, right? And since the
different parallel Flink sinks cannot coordinate this, every parallel
sink will try to saturate every shard, thereby overestimating the
capacity by $sink_parallelism.

Does anyone else have experience with or knowledge about this?

Best regards,
Urs
