> Today, when a ZK operation fails, we handle connection-loss and operation-timeout the same way. This could definitely use some improvements:
> # Add special handling for other error codes
> # Connection-loss: Nullify zkClient, so a new connection is established
> # Operation-timeout: Retry a few times with exponential delay?
