--------------------------------------
Summary: Guarantee debloated buffer size grows even with very
small alpha
Key: FLINK-36555
URL: https://issues.apache.org/jira/browse/FLINK-36555
Project: Flink
Issue Type: Improvement
Components: Runtime / Network, Runtime / Task
Affects Versions: 1.19.1
Reporter: Piotr Nowojski
With small buffer sizes and/or small EMA's alpha, currently it can happen
buffer size won't grow at all. For example:
* current buffer size is 16b
* max new desired size is only capped at 2 * 16b = 32b
* so with alpha ~= 0.03 (or smaller) the new buffer size would be still 16b
