Re: Cache invalidation in Blockcache
then it will be  reloaded in Blockcache along with the Hfile it belongs to
,if  Blockcache is enabled on table

That statement is not so correct..  Because there is no row wise caching.
It is just block of KVs being cached.  So a write will not deal with block
cache as such.  This write will go to Memstore.  During read yes mostly
this version in memstore will come out (as this is most recent)  .. If
maxversions for that table cf is >1 and Scan is requesting more than one
version, mutiple versions of a cell can come out.    Which version u r
using?
