Module mz_adapter::catalog::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.
