TeslaがClickHouseで構築した、1,000兆規模のオブザーバビリティ・プラットフォーム

Tesla, renowned for its expansive operations, has developed an advanced observability platform named "Comet" to manage its immense data requirements, leveraging ClickHouse for its scalability, speed, and durability. Faced with the limitations of existing tools like Prometheus, Tesla's software engineering team, led by Alon Tal, opted for ClickHouse due to its ability to handle Tesla's vast data volumes in real-time, maintain long-term data retention, and support complex queries with flexibility. Comet integrates seamlessly with PromQL, allowing Tesla's engineers to continue using familiar query languages while benefiting from ClickHouse's performance. The system has successfully managed a load of over 1,000 trillion rows without issues, demonstrating exceptional reliability and efficiency. Tesla is considering open-sourcing Comet, reflecting its commitment to innovation and collaboration in the tech community.
