link:{javadoc_base_url}/org/apa
|`walMode` | <<WAL Modes,Write-ahead logging mode>>. | `LOG_ONLY`
| `walCompactionLevel` | WAL archive compression level. `1` indicates the
fastest speed, and `9` indicates the best compression. | `1`
-|`maxWalArchiveSize` | The maximum size (in bytes) the WAL archive can occupy
on the file system. | Four times the size of the
link:persistence/persistence-tuning#adjusting-checkpointing-buffer-size[checkpointing
buffer].
+|`maxWalArchiveSize` | The upper threshold (in bytes) of the WAL archive.
When the archive reaches it, Ignite forcibly releases the reservations of the
segments that the last completed checkpoint already covers, so that the cleanup
can delete them. It is not a hard bound on the directory size. | 1 GiB
+|`minWalArchiveSize` | The threshold (in bytes) that makes segments eligible
for cleanup. The cleanup runs in the background and removes the oldest segments
while the archive stays above this value. Segments are removed as whole files,
so the remaining size can be below it. | Half of `maxWalArchiveSize`
+|`walSegments` | The number of active WAL segments. The volume that holds the
active WAL has to fit that many segments of `walSegmentSize` plus a rotation
reserve. | `10`
+|`checkpointFrequency` | The interval between checkpoints, in milliseconds. A
value that is too small produces frequent checkpoints and a large number of
checkpoint markers. | `180000` (3 minutes)
Review Comment:
just removed `too small` phrase and simlified the statement. Have no
confidence in situations when you really need to change the default. idk
