    Description

      We currently resolve outstanding duplicate keys at the very end of an index build, at the time of commit, while holding a database X lock. If there a lot of duplicates to resolve under a heavy write workload, it may be advantageous to resolve duplicates at every drain phase "MultiIndexBlock::drainBackgroundWritesIfNeeded()".
