Great point and looking forward to Lua support in 2.6. GETRANGE and SETRANGE operations also allow buffered writes at the collection time because setting bit to 1 is an idempotent operation. They are particularly attractive in sharded environment where one can perform:

  WATCH
  bits = GETRANGE ...
  bits = bits | buffered_bits
  MULTI
  SETRANGE .... bits
  EXEC

There is certainly a tipping point between sets and bitsets. Bitsets are far more efficient for storage and for performing unions or intersections for millions of users. For example, for a typical 10% of user base active daily for mobile apps (http://www.avc.com/a_vc/2011/07/301010.html), bit sets will pay off both in storage and performance.

Obviously, each use case is different and for very sparse case, sets would be a better choice.

Encryption provides confidentiality in a secure system. Convergent encryption doesn't fit that bill.

Too little to show for 5 years.
