Maksim Timonin updated IGNITE-21135:
------------------------------------
Description:
`CdcManager` must guarantee that `afterBinaryMemoryRestore()` finishes before
the first call of `collect()`.
Scenario of the contention:
# Ignite node starts, restores binary memory in
GridCacheDatabaseSharedManager#restoreBinaryMemory.
# FileWriteAheadLogManager resumes logging and starts the "wal-segment-syncer"
thread.
# MemoryRecoveryRecord is written
# CdcManager#afterBinaryMemoryRestore method is invoked in the Ignite start
thread.
#
Note, the `collect()` method is called from the background system thread
`wal-segment-syncer`.
In `CdcManager` there is a contention between `collect()` and
`afterBinaryMemoryRestore()` due to Ignite writes the `MemoryRecoveryRecord`.
afterBinaryMemoryRestore should be invoked BEFORE any collect().
