> Set min and max buffer size even if the difference less than threshold

> Key: FLINK-24467
> URL: https://issues.apache.org/jira/browse/FLINK-24467
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.14.0
> Reporter: Anton Kalashnikov
> Assignee: Anton Kalashnikov
> Priority: Major
> Labels: pull-request-available
>
> Right now, we apply a new buffer size only if it differs from the old buffer
> size more than the configured threshold but if the old buffer size is close
> to the max or min value less than this threshold we are always stuck on this
> value. For example, if we have the old buffer size 22k and our threshold is
> 50% then the value which we can apply should 33k but this is impossible
> because the max value is 32k so once we calculate the buffer size to 22k it
> is impossible to increase it.
> The suggestion is to apply the changes every time when we calculate the new
> value to min or max size and the old value was different.
