类 AllPrimaryKeyEqualVisitor

java.lang.Object

org.apache.paimon.predicate.AllPrimaryKeyEqualVisitor

所有已实现的接口:

FunctionVisitor<Set<String>>, PredicateVisitor<Set<String>>

public class AllPrimaryKeyEqualVisitor
extends Object
implements FunctionVisitor<Set<String>>

Visit the predicate and check if it only contains primary keys and can be push down.

We will check: all the primary keys are in the predicate with equal operator.

TODO: support IN.
