Struct mz_compute::compute_state::DroppedCollection

source · 
pub struct DroppedCollection {
    reported_frontiers: ReportedFrontiers,
    is_subscribe_or_copy: bool,
}
Expand description

State remembered about a dropped compute collection.

This is the subset of the full CollectionState that survives the invocation of drop_collection, until it is finally dropped in report_dropped_collections. It includes any information required to report the dropping of a collection to the controller.

Note that this state must not store any state (such as tokens) whose dropping releases resources elsewhere in the system. A DroppedCollection for a collection dropped during reconciliation might be alive at the same time as the CollectionState for the re-created collection, and if the dropped collection hasn’t released all its held resources by the time the new one is created, conflicts can ensue.
