Fields

dispatcher_update: Vec<DispatcherUpdate>

Dispatcher updates.

merge_update: Vec<MergeUpdate>

Merge updates.

actor_vnode_bitmap_update: HashMap<u32, Buffer>

Vnode bitmap updates for each actor.

dropped_actors: Vec<u32>

All actors to be dropped in this update.

actor_splits: HashMap<u32, ConnectorSplits>

Source updates. Source and SourceBackfill are handled together here.

actor_new_dispatchers: HashMap<u32, Dispatchers>

When modifying the Materialized View, we need to recreate the Dispatcher from the old upstream to the new TableFragment. Consistent with the semantics in AddMutation.
