> 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.
