Class RecordUsageAnalyser

java.lang.Object

org.apache.jackrabbit.oak.plugins.segment.SegmentParser

org.apache.jackrabbit.oak.plugins.segment.RecordUsageAnalyser

public class RecordUsageAnalyser
extends SegmentParser

This utility breaks down space usage per record type. It accounts for value sharing. That is, an instance of this class will remember which records it has seen already and not count those again. Only the effective space taken by the records is taken into account. Slack space from aligning records is not accounted for.
