> 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.
