How does cratedb handle updates to the path.data?

Question

Specifically, regarding the pseudo-RAID0 setup:

path.data: /path/to/data1,/path/to/data2

• How does cratedb handle it if i add more paths to an existing node?
  • Will it work?
  • Will it rebalance the data or only balance as new data arrives?

Answer 1

• you can add more paths anytime.

• the existing shards won't be reshuffeled. rebalancing only happens between the nodes. you can read more about the thresholds here: https://crate.io/docs/reference/configuration.html#routing-allocation
