This release adds new control over Raft snapshotting, a key part of the Raft consensus protocol. When the WAL file reaches a certain size (16MB by default), rqlite will trigger a Raft snapshot. Most users can ignore this feature and carry on as before after upgrading to this release.
This release adds new control over Raft snapshotting, a key part of the Raft consensus protocol. When the WAL file reaches a certain size (4MB by default), rqlite will trigger a Raft snapshot. In its default setting this change may reduce disk usage, but may also result in more frequent Raft snapshotting. Most users can ignore this change and carry on as before after upgrading to this release.
