类 OnlyPartitionKeyEqualVisitor

java.lang.Object

org.apache.paimon.predicate.OnlyPartitionKeyEqualVisitor

所有已实现的接口:

FunctionVisitor<Boolean>, PredicateVisitor<Boolean>

public class OnlyPartitionKeyEqualVisitor
extends Object
implements FunctionVisitor<Boolean>

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

TODO: more filters if BatchWriteBuilder supports predicate.
