ClickHouse is an open source column-oriented database management system originally developed as a backend for Yandex's Metrica analytics platform. It achieves optimal performance with a maximum of 100 queries per second on a single instance and a minimum of 1,000 rows for each INSERT query. Datadog integrates with ClickHouse to provide full visibility into big data analytics jobs, allowing users to track read and write performance over time, compare query throughput with query resource usage, and monitor ZooKeeper connections. The integration also enables users to ship logs from all ClickHouse instances to Datadog, enriching the logs with metadata for easier searching and filtering, and plotting trends over time. With this integration, users can gain comprehensive visibility into their distributed analytics jobs alongside other technologies, including Apache Kafka, and sign up for a free trial if needed.
