Abstract
An extractor and an applier of a database replication system are configured to perform the functions of resolving target database constraint violations for replicated database transactions. The extractor replicates changes made at the source database to the target database. An applier immediately applies the changes to the target database that do not cause a constraint violation. The applier also performs the remaining functions, including detecting database changes that cause constraint violations, subsequent processing of these detected database changes, and performing a commit for the database transaction when the constraint violations are resolved.
