hi all, can you advise if running GreptimeDB using local WAL in prod is a common practice? Local WAL | GreptimeDB Documentation Kafka is so outdated and we dont use it in our clusters. introducing Kafka also means a whole bunch of components to monitor and maintain, and many points of failures. i'd like to hear your experience running GreptimeDB in prod using only local WAL? is switching between local WAL and noop WAL seemingless? if i want to take a node down for node maintenance, what are the steps i should take to ensure no service disruptions? e.g. switching to noop WAL, then take the node down?

Yes. But we mount the local WAL (the whole data_home) on cloud blob storage, such as EBS.

got it, thanks for sharing
