----------------------------------------------------------------
This bug is pretty stable in IGNITE-17081, flaky rate of
ItIgniteNodeRestartTest#nodeWithDataTest goes through the roof on the warmed-up
JVM.
The reason is that, presumably, node startup (partitions recovery) became
faster in that branch.

> Issue Type: Bug
> Reporter: Denis Chudov
> Priority: Major
>
> RocksDbKeyValueStorage recreates DB on start. This means that entries that
> were put to this storage earlier, can or cant be found until raft log is
> replayed, i.e. the behavior is undefined. For example, this can cause
> assertion on node recovery:
> {code:java}
> java.lang.AssertionError: Configuration revision must be greater than local
> node applied revision [msRev=0, appliedRev=1
> {code}
> which means that applied revision in vault is 1 but only 0 is found in meta
> storage, as the storage of meta storage is being recreated.
> For now, the only thing that saves us from this assertion to be thrown every
> time, is that operations related to node recovery, applied from distributed
> configuration (see IgniteImpl#notifyConfigurationListeners ), take some time
> and raft log is small enough to replay faster than the performing of recovery
> operations.
