   >what's community's plan for BanyanDB to adopt a fault-tolerant, multi-replicas structure (using Raft or other algorithms). 
   
   Relevant feats are under discussion. 
   
   > 1. If BanyanDB pod fails (network partition, worker node down), do we have to restart and wait for it to recover, or have other failovers like activating a slave backup?
   
   BanyanDB will know nodes' roles. The operator doesn't take care of recovery. Restarting the pod is acceptable. 
   
   
   > 2. If users changes BanyanDB version and its docker image, can we rolling update BanyanDB while still providing normal service? Does BanyanDB support hot-update for its start-up configurations?
   
   The rolling update is a complicated topic. We don't have any discussions in the community. The operator could leave it as is now and refine the CRD once it's on our radar.
