-------------------------------------
Resolution: Fixed
> Add ability to disable WAL for ceratin caches in runtime
> --------------------------------------------------------
>
> Key: IGNITE-6411
> URL: https://issues.apache.org/jira/browse/IGNITE-6411
> Project: Ignite
> Issue Type: Task
> Components: persistence
> Affects Versions: 2.1
> Reporter: Vladimir Ozerov
> Priority: Major
> Labels: iep-1, performance
> Fix For: 2.5
>
>
> Currently every cache update require write to WAL. When doing bulk data load
> usually crash recovery is not needed. If something went wrong during data
> load, we should simply purge all intermediate data on cache restart.
> It makes sense to add ability to disable WAL for ceratin caches. Depending on
> restrictions of current architecture, it could be done on per-cache,
> per-cache-group or per-memory-policy level.
