Redis 4.2 roadmap

  1. Redis Cluster
  • Speed up key -> hashslot association. Now makes RBB loading 4x slower when there are many small keys.
  • Better multi data center story
  • redis-trib C coded and moved into redis-cli
  • Backup / Restore of Cluster
  • Non blocking MIGRATE (also consider not using 2X memory)
  • Faster resharding
  • Bug fixing and stress testing to bring it to next level of maturity
