> 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.
