Enum mz_adapter::coord::validity::PlanValidity
source · pub enum PlanValidity {
RequireRevision {
required_revision: u64,

cluster_id: Option<ComputeInstanceId>,

Expand description
A struct to hold information about the validity of plans and if they should be abandoned after doing work off of the Coordinator thread.
Variants§
RequireRevision
Requires a specific transient revision.
Checks
Checks various catalog IDs. Uses the transient revision only as a cache marker.
Fields
§
dependency_ids: BTreeSet<CatalogItemId>
Objects on which the plan depends.
§
cluster_id: Option<ComputeInstanceId>
§
role_metadata: RoleMetadata
Implementations§
source§impl PlanValidity
impl PlanValidity
pub fn new( transient_revision: u64, dependency_ids: BTreeSet<CatalogItemId>, cluster_id: Option<ComputeInstanceId>, replica_id: Option<ReplicaId>, role_metadata: RoleMetadata, ) -> Self
sourcepub fn require_transient_revision(required_revision: u64) -> Self
pub fn require_transient_revision(required_revision: u64) -> Self
WARNING: This is currently a no-op and check
will always succeed.
Sets the required transient_revision
of the catalog. Should only be used by serialized
statements (and thus should never fail for users), but here as an internal failsafe against
programming errors.
sourcepub fn extend_dependencies(&mut self, ids: impl Iterator<Item = CatalogItemId>)
pub fn extend_dependencies(&mut self, ids: impl Iterator<Item = CatalogItemId>)
Panics if not called on a Checks variant.
