> Key: FLINK-28027
> URL: https://issues.apache.org/jira/browse/FLINK-28027
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Common, Connectors / Kinesis
> Affects Versions: 1.15.0, 1.15.1
> Reporter: Zichen Liu
> Assignee: Hong Liang Teoh
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.15.2
>
>
> *Background*
> In the AsyncSinkWriter, we implement a rate limiting strategy.
> The initial value for the maximum number of in flight messages is set
> extremely high ({{{}maxBatchSize * maxInFlightRequests{}}}).
> However, in accordance with the AIMD strategy, the TCP implementation for
> congestion control has found a small value to start with [is
> better]([https://en.wikipedia.org/wiki/TCP_congestion_control#Slow_start]).
> *Suggestion*
> A better default might be:
> * maxBatchSize
> * maxBatchSize / parallelism
