Issue Description

One day(05/12 on the screenshot), I noticed that the number of entries in a bookie increased significantly. At the same time, minor and major compactions started taking much longer to complete. According to the metrics, there’s nothing unusual happening in the topics — no spikes in topic backlogs either. How can I figure out what these entries are and where they're coming from?
