[jira] [Created] (IGNITE-18718) WALPointer doesn't allow to shift on compacted segments

Maksim Timonin created IGNITE-18718:
---------------------------------------

             Summary: WALPointer doesn't allow to shift on compacted segments
                 Key: IGNITE-18718
                 URL: https://issues.apache.org/jira/browse/IGNITE-18718
             Project: Ignite
          Issue Type: Bug
            Reporter: Maksim Timonin


WALPointer contains offset field. While creating a new WALIterator it's possible to set "from" param to IteratorParameresBuilder.

Then iterator tries to skip "offset" amount of bytes in current file. It works for original wal segment, but doesn't work for compacted (offset value is likely incorrect, as compacted segments don't contain physical records).
