Replay Configuration

You can tune the snapshot-trigger-size and snapshots-to-keepEngine 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.

See Managing Disk Space Used by Transaction Logs and Configuring Transaction Logs and Snapshots for more information.
