Replay Configuration
You can tune the snapshot-trigger-size
and snapshots-to-keep
Engine Variables to make efficient use of the logs and snapshots.
A large snapshot-trigger-size
decreases the frequency that snapshots are taken. But a large snapshot-trigger-size
increases the time needed to replay the snapshot.
A large snapshots-to-keep
increases the number of snapshots available, and it increases the amount of space needed to store the snapshots and logs.
snapshots-to-keep
defaults to 2
.
The datadir
engine variable stores the location of the snapshots and logs.
