dev.frostlake.metastore.model.ConstraintNames

public final class ConstraintNames
extends Object

Names for constraints declared without an explicit CONSTRAINT <name> clause. Snowflake names such a constraint SYS_CONSTRAINT_<uuid> — e.g. SYS_CONSTRAINT_0a022251-e083-4354-a48d-a7cdffba5738 — for PRIMARY KEY, UNIQUE and FOREIGN KEY alike (live-verified through INFORMATION_SCHEMA.TABLE_CONSTRAINTS). The name carries no information about the table, the columns, or the constraint kind, so callers must never parse it; they only need it to stay stable for the lifetime of the constraint, which is why every generated name is memoized next to the constraint it names (see Table and ForeignKeyConstraint).
