By automatically detecting and reloading changed certificates, ClickHouse ensures secure connections are maintained seamlessly and reduces operational overhead.How to use it
Users simply need to replace the TLS certificate files on disk as usual. ClickHouse will detect these changes and reload the certificates automatically without requiring aSYSTEM RELOAD CONFIG command.
