Module apply

Logic related to applying updates from a mz_catalog::durable::DurableCatalogState to a CatalogState.

Structs

InProgressRetractions 🔒

Maintains the state of retractions while applying catalog state updates for a single timestamp. CatalogState maintains denormalized state for certain catalog objects. Updating an object results in applying a retraction for that object followed by applying an addition for that object. When applying those additions it can be extremely expensive to re-build that denormalized state from scratch. To avoid that issue we stash the denormalized state from retractions, so it can be used during additions.

Enums

BootstrapApplyState 🔒

Most updates are applied one at a time, but during bootstrap, certain types are applied separately in a batch for performance reasons. A constraint is that updates must be applied in order. This process is modeled as a state machine that batches then applies groups of updates.

Functions

apply_inverted_lookup 🔒

Helper method to updated inverted lookup maps. The keys are generally names and the values are generally IDs.

apply_with_update 🔒

Helper method to update catalog state, that may need to be updated from a previously retracted object.

lookup_builtin_view_addition 🔒

Looks up a BuiltinView from a SystemObjectMapping.

sort_updates 🔒

Sort StateUpdates in timestamp then dependency order

sort_updates_inner 🔒

Sort StateUpdates in dependency order for a single timestamp.
