| <p>From the 3.0 upgrade notes:</p> |
| </div> |
| <div class="paragraph"> |
| <p>New transaction log files have been introduced to replace the |
| compactions_in_progress system table, temporary file markers (tmp and |
| tmplink) and sstable ancestors. Therefore, compaction metadata no longer |
| contains ancestors. Transaction log files list sstable descriptors |
| involved in compactions and other operations such as flushing and |
| streaming. Use the sstableutil tool to list any sstable files currently |
| involved in operations not yet completed, which previously would have |
| been marked as temporary. A transaction log file contains one sstable |
| per line, with the prefix "add:" or "remove:". They also contain a |
| special line "commit", only inserted at the end when the transaction is |
| committed. On startup we use these files to cleanup any partial |
| transactions that were in progress when the process exited. If the |
| commit line is found, we keep new sstables (those with the "add" prefix) |
| and delete the old sstables (those with the "remove" prefix), vice-versa |
| if the commit line is missing. Should you lose or delete these log |
| files, both old and new sstable files will be kept as live files, which |
| will result in duplicated sstables. These files are protected by |
| incremental checksums so you should not manually edit them. When |
| restoring a full backup or moving sstable files, you should clean-up any |
| left over transactions and their temporary files first.</p> |
