Graphite-Clickhouse w/Clickhouse cluster Testing / TLDR

What is it?

Preconfigured graphite-web (and carbonapi) with ClickHouse cluster backend deployed by docker-compose. Also contains Grafana and Haggar.

Why?

Similar repo exists for single clickhouse server - this one also contains Zookeeper and configurable Clickhouse cluster. You can learn how Clickhouse cluster works and how graphite-clickhouse scales.

WARNING

This repo is only an experiment and designed for learning and experiments. Please do not use it in production!

Clickhouse cluster

Clickhouse cluster consists of 6 nodes, 3 shards x 2 replicas.

So, shards = [ch01/ch06], [ch02/03], [ch04/05].
Or, from replicas side of view - [ch01/ch02/ch04], [ch06/ch03/ch05]

Do not forget to sync proxy config chproxy/config.yml with real cluster config in ch/config/macros and ch/config/clickhouse_metrika.xml

Also do not forget to rerun docker-compose build after changing chproxy/config.yml.

TODO

Chaos (using Pumba) - with metric delay and availability monitoring.
