Description

PropertyIndexCleaner currently remove the property index bucket in a single remove. This would work fine with SegmentNodeStore but would cause issue with DocumentNodeStore where it would result in a one large commit.

To avoid this scenario we should implement recursive delete. This approach would only be used if NodeStore implements Clusterable
