Thanks Udo for your quick guidance.
I have referred the reference provided by you, and it seems I can create my
own implementation of *CustomExpiry *and in the implementation of*
getExpiry(Entry entry) *can set the desired ExpirationAttributes for
targetted entries in my partition region. I will certainly give a try to
this.
>From the doc, it seems there is async expiration thread who is responsible
of this, It would be great help if some one gives me brief details on
following,
1. How can I make sure that for a particular day (or 24 hours span)
expiration thread only do it job once (or in a off time),
would like to avoid frequent expiration checks, as it may be overkill,
and not required for my case as date changes in 24 hrs.
2. Brief workflow of row's expiration when one provides customExpiry
configuration - to understand this better.
Thanks in advance.
-U.
