compactdb blocks other clients

[hotpxl]

I'm running ARDB with RocksDB as a backend. My database is around 100 GB. I usually have one window with watch redis-cli info to monitor the status, and if I do redis-cli compactdb and wait a while, the first window will freeze. All requests to ARDB will get blocked for a while until the compaction ends.

This doesn't happen right away when I start compaction, only after a short while. I haven't looked too deep into this. Is this a known issue?
