Yes, But the rebalance command doesn't do what I would like.
Let's suppose that I've : SPOUT A (1) => BOLT 1 (1) => BOLT2 (1) => BOLT3 (3) (number is the parallelism hint) It means that If I scale to n worker I would like : SPOUT A (1*n) => BOLT 1 (1*n) => BOLT2 (1*n) => BOLT3 (3*n) But, the storm rebalance keeps the parralisme_hint :/ 2016-06-09 14:29 GMT+02:00 Andrew Xor <[email protected]>: > Hello, > > Why not use the rebalance command?
