Nice, I'm using Clickhouse to build Luabase[0]. I saw "ClickHouse cluster support" on your roadmap, are you just using a single node right now? How are you handling persistent storage?

By cluster support I mean:

- ability to use ReplicatedMergeTree in the table schema

- round-robin writing to multiple nodes

It is mostly a matter of providing configuration options. Thought I could skip it in the first release.

>How are you handling persistent storage?

If you mean avoiding data loss by using ClickHouse cluster, then yes - we use CH cluster and replication :)

ClickHouse handles data corruption surprisingly good - even if there are broken parts CH continues to serve the rest of data.

Where is the clickhouse data stored, in the Docker container?

For reference, here's what I'm using: https://github.com/Altinity/clickhouse-operator/blob/master/...

I've provided a Docker example so users can quickly try Uptrace without downloading and configuring anything. I don't use Docker to run anything besides examples so can't give any recommendations.

Thanks for the clickhouse-operator though. I guess we will have to provide something for k8s sooner or later.

Got it. I might be missing something, but if you deployed it this way and needed to rebuild the Docker image, you'd lose all your data, right?

That's what volumes are for
