We're starting a special series of articles dedicated to our… failures and lessons we've learned from them. This story has happened with a ClickHouse + ZooKeeper setup due to miscommunication.

Our new exciting SRE/Ops stories include complicated Linux server migration (bare-metal to VM), large PostgreSQL replica recovery, small case with ClickHouse Kubernetes operator, and abnormal result of CockroachDB upgrade.

Our stories include a poorly prepared Kafka in Docker, an unexpected network issue for ZooKeeper & ClickHouse, a faulty hardware in the data center, and the PgSQL database optimization.
