This is a really interesting design - kudos.

Is there any handling for tombstone records?

WarpStream doesn't implement compacted topics today. It is on our roadmap, though. Compacted topics are typically not used in high-throughput workloads, so our plan is to delay compactions for longer than a disk-based system would to trade space amplification for write amplification.

  Thanks for clarifying.

  TIL, but it makes sense. Compaction/retention policies certainly introduce a lot of extra tradeoffs dimensions.
