> Currently if there are several updates for the same key, write behind store will write only one of them within a single batch. I.e. second update will override the first one if the latter is not written to DB yet.
> This is good from performance and memory consumption standpoint, however sometimes it's required to write all updates that happen in cache.
> We can add parameter to {{CacheConfiguration}} that will switch this behavior and implement it in {{GridCacheWriteBehindStore}}. Default behavior should remain the same.
