[jira] [Created] (CASSANDRA-15364) Avoid over scanning data directories in LogFile.verify()

Marcus Eriksson created CASSANDRA-15364:
-------------------------------------------

             Summary: Avoid over scanning data directories in LogFile.verify()
                 Key: CASSANDRA-15364
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15364
             Project: Cassandra
          Issue Type: Bug
            Reporter: Marcus Eriksson
            Assignee: Marcus Eriksson


We currently list the data directory for every `REMOVE` record in the file in `LogFile.verify()` - this can get very expensive during startup when we call `LogTransaction.removeUnfinishedLeftovers()`. In `LogRecord.getExistingFiles(Set<String> absoluteFilePaths)` we also fully parse the file name of the sstables found, here we only need to prefix match.
