[jira] [Created] (IGNITE-4933) Need to add an option to write all
updates in write-behind store
Valentin Kulichenko created IGNITE-4933:
-------------------------------------------
Summary: 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
Fix For: 2.0
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.
