Kuzzle 2.59 #

Released: 2026-10-01. GitHub release.

In short #

2.59 adds two building blocks for maintenance tools that rebuild a collection while Kuzzle keeps running, such as a mapping migration. Nothing changes if you don't use them.

What you need to do #

Nothing.

What's new #

• Collection write locks. A collection can be locked for writing across the whole cluster. While it is locked, every write on it (document writes, bulk imports, mapping updates, truncate, delete) is refused with the new services.storage.collection_locked error (503), and reads keep working. Only server-side code can lock a collection: there is no API action for it.
• Unmanaged indices (Elasticsearch 8). An Elasticsearch index that carries the kuzzle-unmanaged alias is ignored by Kuzzle's startup repairs and its storage statistics. A tool can build a collection's next index beside it without Kuzzle mistaking it for a collection.
