- Sets pacing to pause purge in between queries during a purge action to allow other operations to access the database. The default value is 0.
- Sets the max duration for an entire purge cycle such that no new classes will be purged when the limit is reached. However, the class being purged will complete normally. The default value is 0.
- Sets the batch size for the bulk delete operation of records in the Elasticsearch index. The default value is 1000.
- Sets the number of records that a subquery delivers to the delete statement. The default value is 100000.
