> any timeline when we can expect a patch for it?
We hope to have an answer to this by next week.
> Scheduled Repair in Cassandra

> There have been many attempts to automate repair in Cassandra, which makes
> sense given that it is necessary to give our users eventual consistency. Most
> recently CASSANDRA-10070, CASSANDRA-8911 and CASSANDRA-13924 have all looked
> for ways to solve this problem.
> At Netflix we've built a scheduled repair service within Priam (our sidecar),
> which we spoke about last year at NGCC. Given the positive feedback at NGCC
> we focussed on getting it production ready and have now been using it in
> production to repair hundreds of clusters, tens of thousands of nodes, and
> petabytes of data for the past six months. Also based on feedback at NGCC we
> have invested effort in figuring out how to integrate this natively into
> Cassandra rather than open sourcing it as an external service (e.g. in Priam).
> As such, [~vinaykumarcse] and I would like to re-work and merge our
> implementation into Cassandra, and have created a [design
> document|https://docs.google.com/document/d/1RV4rOrG1gwlD5IljmrIq_t45rz7H3xs9GbFSEyGzEtM/edit?usp=sharing]
> showing how we plan to make it happen, including the the user interface.
> As we work on the code migration from Priam to Cassandra, any feedback would
> be greatly appreciated about the interface or v1 implementation features. I
> have tried to call out in the document features which we explicitly consider
> future work (as well as a path forward to implement them in the future)
> because I would very much like to get this done before the 4.0 merge window
> closes, and to do that I think aggressively pruning scope is going to be a
> necessity.
