------------------------------------------

             Summary: Searching checkpoint record in WAL doesn't work with segment compaction
                 Key: IGNITE-12459
                 URL: https://issues.apache.org/jira/browse/IGNITE-12459
             Project: Ignite
          Issue Type: Bug
            Reporter: Anton Kalashnikov
            Assignee: Anton Kalashnikov


During iteration over WAL we have two invariants about result(Tuple<WALPointer, WALRecord>):
* WALPointer equal to WALRecord.position() when segment is uncompacted
* WALPointer not equal to WALRecord.position() when the segment is compacted
Unfortunately, the second variant is broken in FileWriteAheadLogManager#read(WALPointer ptr)
