> *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
