    Description

      The goal of this ticket is to improve/understand the bottlenecks during compactions. At a high level this will involve:

      • A test system for measuring compaction time for different workloads and compaction strategies.
      • Profiling and analysis
      • Make improvements
      • Add throughput regression tests so we can track

      We have a lot of random tickets that relate to this so I'll link them to this ticket
