Interface CollectionStateWatcher

    • Method Detail

      • onStateChanged

        boolean onStateChanged​(Set<String> liveNodes,
                               DocCollection collectionState)
        Called when either the collection we are registered against has a change of state or there is a change to the live nodes of our collection.

        Note that, due to the way Zookeeper watchers are implemented, a single call may be the result of several state changes. Also, multiple calls to this method can be made with the same state, ie. without any new updates.

        liveNodes - the set of live nodes
        collectionState - the new collection state (may be null if the collection has been deleted)
        true if the watcher should be removed
