Class PartitionedUniquenessVerifier

java.lang.Object

org.neo4j.kernel.api.impl.schema.verification.PartitionedUniquenessVerifier

All Implemented Interfaces:

Closeable, AutoCloseable, UniquenessVerifier

public class PartitionedUniquenessVerifier
extends Object
implements UniquenessVerifier

A UniquenessVerifier that is able to verify value uniqueness across multiple index partitions using corresponding PartitionSearchers.

This verifier reads all terms from all partitions using MultiTerms, checks document frequency for each term and verifies uniqueness of values from the property store if document frequency is greater than 1.

Description copied from interface: UniquenessVerifier

Verifies uniqueness of existing data.

Specified by:

verify in interface UniquenessVerifier

Parameters:

accessor - the accessor to retrieve actual property values from the store.

propKeyIds - the ids of the properties to verify.

Throws:

org.neo4j.kernel.api.exceptions.index.IndexEntryConflictException - if there are duplicates.
