Kirill Tkalenko updated IGNITE-23479:
-------------------------------------
Description:
We need to add a method to
*org.apache.ignite.internal.metastorage.server.KeyValueStorage* that will
perform steps 4.1 - 4.7 from IGNITE-23293.
Algorithm:
# If the storage is in the recovery state, then we set a new compaction
revision (*KeyValueStorage#setCompactionRevision*) and complete the method.
2. Otherwise, adds a new task (A) to the WatcheEvent queue and complete the
method.
3. Task (A) sets a new compaction revision
(*KeyValueStorage#setCompactionRevision*) and adds a new task (B) to the
compaction thread pool and completes.
4. Task (B) collects all read operations for a revision less than the new one
and asynchronously begins to wait for their completion and starts a local
compaction (*KeyValueStorage#compact*).
5. After the compaction is complete, notifies about its completion.
