Every 1 hour, compaction manager will submit all registered table_state for a regular compaction attempt, all without yielding. This can potentially cause a reactor stall if there are 1000s of table states, as compaction strategy heuristics will run on behalf of each, and processing all buckets and picking the best one is not cheap. This problem can be magnified with compaction groups, as each group is represented by a table state. This might appear in dashboard as periodic stalls, every 1h, misleading the investigator into believing that the problem is caused by a chronological job. This is fixed by piggybacking on compaction reevaluation loop which can yield between each submission attempt if needed. Fixes #12390. Signed-off-by: Raphael S.
