GoKawiilTinybird engineer details six years of running petabyte-scale ClickHouse clusters
A Tinybird engineer who has operated ClickHouse clusters since version 18.4 nearly six years ago published a detailed retrospective on running the database at petabyte scale. The post walks through the standard shard-and-replica architecture ClickHouse recommends and highlights the operational pitfalls that only surface once a cluster is running in production. Tinybird notes it is an independent contributor to the open-source project and unaffiliated with ClickHouse, Inc.
