I agree that it would be ideal for Cassandra to have a repair scheduler in-DB.
That said I would happily support an effort to bring repair scheduling to the sidecar immediately. This has nothing blocking it, and would potentially enable the sidecar to provide an official repair scheduling solution that is compatible with current or even previous versions of the database. Once TCM has landed, we’ll have much stronger primitives for repair orchestration in the database itself. But I don’t think that should block progress on a repair scheduling solution in the sidecar, and there is nothing that would prevent someone from continuing to use a sidecar-based solution in perpetuity if they preferred. - Scott > On Jul 26, 2023, at 3:25 PM, Jon Haddad <rustyrazorbl...@apache.org> wrote: > > I'm 100% in favor of repair being part of the core DB, not the sidecar.
