Some question regards near cache and cache store

Hi All, 

Will REPLICATED mode cache can not use the NearCacheConfiguration?   Also the affinity should not be used for REPLICATED mode cache right? 

Possible evict some data from the cache manually, when use JDBC storage as back-end;  for some entry, I only want to mark them as deleted  and move away from cache not really delete from DB.

Thanks for your time! very appreciate!

Regards
Aaron

Hi Aaron,

NearCacheConfiguration can be used for REPLICATED cache. It can be useful
for client node. Affinity function used also for REPLICATED caches.

IgniteCache#clear method does what you want.
