------------------------------------
> Need to add an option to write all updates in write-behind store
> ----------------------------------------------------------------
>
> Key: IGNITE-4933
> URL: https://issues.apache.org/jira/browse/IGNITE-4933
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 1.9
> Reporter: Valentin Kulichenko
> Assignee: Yakov Zhdanov
> Fix For: 2.0
>
> Time Spent: 16h
> Remaining Estimate: 0h
>
> 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.
