Hello, I see that, in Flink 1.17.1, watermark alignment will be supported (as beta) within a single source's splits and across different sources. I don't see this explicitly mentioned in the documentation, but I assume that the concept of "maximal drift" used for alignment also takes idleness into account, resuming any readers that were paused due to an idle split or source. Is my understanding correct?
Also, something that isn't 100% clear to me when comparing to the previous watermark alignment documentation, even if I only wanted alignment within a single source's splits, I still need to call withWatermarkAlignment in the watermark strategy, right? Otherwise alignment will not take place, regardless of pipeline.watermark-alignment.allow-unaligned-source-splits. Regards, Alexis.
