      Description

      Today when a put(record) call on a windowed store does not find the corresponding segment, i.e. its corresponding's window has expired, we simply returns a null and hence silently drops it.

      We should consider 1) add log4j entries when it happens, 2) add metrics (we can discuss whether it should be a processor-node level, or store level sensor) for such cases.
