    Description

      Transactions which touch (or not) various shards can end up leaving holes in the transaction sequence numbers in shards which are not touched. This can end up growing the tracking rangesets, effectively leaking storage.

      Devise a recovery strategy, which will ensure that backends can merge up holes in a (relatively) timely fashion.
