Sumanth Pasupuleti updated CASSANDRA-14347:
-------------------------------------------
Description: (was: 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.)
