Raw Blame History

v3.1.13 (TBD)

See code changes and v3.1 upgrade guide for any breaking changes.

Improved

Adjust election timeout on server restart to reduce disruptive rejoining servers.
- Previously, etcd fast-forwards election ticks on server start, with only one tick left for leader election. This is to speed up start phase, without having to wait until all election ticks elapse. Advancing election ticks is useful for cross datacenter deployments with larger election timeouts. However, it was affecting cluster availability if the last tick elapses before leader contacts the restarted node.
- Now, when etcd restarts, it adjusts election ticks with more than one tick left, thus more time for leader to prevent disruptive restart.

v3.1.12 (2018-03-08)

See code changes and v3.1 upgrade guide for any breaking changes.

Fixed

Fix mvcc "unsynced" watcher restore operation.
- "unsynced" watcher is watcher that needs to be in sync with events that have happened.
- That is, "unsynced" watcher is the slow watcher that was requested on old revision.
- "unsynced" watcher restore operation was not correctly populating its underlying watcher group.
- Which possibly causes missing events from "unsynced" watchers.
