Postgres vs ClickHouse? I use both. 4 tricks from the split.

The author splits their monitoring data between Postgres and ClickHouse based on whether a row's data changes. Config data, which frequently gets updated, is stored in Postgres for its robust transaction and constraint capabilities. Meanwhile, check results, which are written once and remain static, are stored in ClickHouse to optimize performance and cost. The author shares four practical tricks for managing this split, emphasizing efficient data handling and cost-effectiveness, which are valuable insights even for users of a single database system. This approach highlights the importance of choosing the right database for specific use cases.
