------------------------------------
Issue Type: Task (was: Sub-task)
Parent: (was: IGNITE-6411)
> Ability to disable WAL (Non recoverable case)
> ---------------------------------------------
>
> Key: IGNITE-7003
> URL: https://issues.apache.org/jira/browse/IGNITE-7003
> Project: Ignite
> Issue Type: Task
> Components: cache, persistence, sql
> Reporter: Anton Vinogradov
> Assignee: Vladimir Ozerov
> Priority: Major
> Fix For: 2.4
>
>
> 1) WAL should be disabled by custom discovery message
> - without triggering exchange,
> - without triggering checkpoint (since it's non recoverable case)
> In case someone is trying to disable already disabled WAL he should be
> notified that WAL already disabled
> Only cachegroups containing one cache can de disabled
> 2) WAL should be prepared to be enabled by custom discovery message with
> - triggering exchange,
> - disabling cache proxies,
> - waiting for checkpoints at every node.
> In case someone is trying to enable already enablling WAL he should be
> notified that enabling in progress.
> 3) WAL should be enabled by custom discovery message
> - without triggering exchange
> but
> - with enabling proxies
> once all nodes finished their checkpoints.
> Failover:
> On any failure during loading (while WAL disabled or enabling) we should be
> able to reactivate cluster without affected caches content.
> Originating node fail should be covered (at WAL disabled and enabling cases)
> API:
> Public API should be located at IgniteCluster
