A silly question: Why is it using self-defined clickhouse charts instead of bitnamis?

[d0zingcat]

Just want to know the differences between the two and is there any effects on it if I am using a bitnami clickhouse charts?(by using externalClickhouse)

Bitnami chart does work.

Wasn't available at the time of the chart creation.

I think using the clickhouse operator is a much better solution.

We have already deployed it clickhouse chart -https://github.com/sentry-kubernetes/charts/tree/develop/charts/clickhouse.
Unfortunately it use old version of clickhouse.
If we decide to change it other implementation, is that means we will lost existing data or we need to migrate them?
