Description

Does st2.conf file support adding redundant pairs of backend coordinator like zookeeper or redis? We have zookeeper cluster (3 instances) but not sure how to include 3 instances in st2.conf. Tried below config but doesn't work.

[coordination] url = kazoo://user:pass@host1:2181/, kazoo://user:pass@host2:2181/, kazoo://user:pass@host3:2181/

Contributor guide

Research direction
Research how StackStorm's coordination backend supports multiple URLs and verify the correct syntax for comma separated or newline separated entries in st2.conf. Check official docs or source code for kazoo URL format with multiple hosts.
