Paul Lin commented on FLINK-22300:
----------------------------------
[~arvid] For a usage case, how about a global window (no window size is
defined) that relies on a processing time TimeEvictor to clean up the elements?
RWT the solution, I think maybe in case of processing time we can attach the
processing timestamp to the TimestampedValue in window assigners and erase them
after evictors. WDYT?
