Why redis cluster resharding is not automatically? -

-

when add node in redis cluster, has 0 hash slots. why redis cluster doesn't automatically resharding operation in order make new node functional?

the process of adding node consists of 2 steps:

  1. introduce node other nodes via cluster meet nodes start communicate via cluster bus
  2. make node act master via cluster addslots or slave via cluster replicate

the separation helps keep commands simple.

automatic resharding part of redis 4.2 roadmap
