I think this solution would solve one of the problems that Aiven has with node replacement currently. Though TCM will probably help as well. On Mon, Apr 15, 2024 at 11:47 PM German Eichberger via dev < dev@cassandra.apache.org> wrote: > Thanks for the proposal. I second Jordan that we need more

Hi, If there is a faster/better way to replace a node why not have Cassandra support that natively without the sidecar so people who aren’t running the sidecar can benefit? Copying files over a network shouldn’t be slow in C* and it would also already have all the connectivity issues solved.

Hi, I think it’s a good quality of life improvement, but I am someone who believes in a rich set of built-in functions being a good thing. A format function is a bit more scope and kind of orthogonal. It would still be good to have shorthand functions for things like size. Ariel On Tue, Apr 9

Ariel, having it in C* process makes sense to me. Please correct me if I'm wrong here, but shouldn't using ZCS to transfer have no distinguishable difference in overhead from doing it using the sidecar? Since the underlying call is sendfile, never hitting userspace, I can't see why we'd opt for t

Hmm... I guess if you're using encryption you can't use ZCS so there's that. It probably makes sense to implement kernel TLS: https://www.kernel.org/doc/html/v5.7/networking/tls.html Then we can get ZCS all the time, for bootstrap & replacements. Jon On Thu, Apr 18, 2024 at 12:50 PM Jon Haddad

2024-04-18 Thread Francisco Guerrero
My understanding from the proposal is that Sidecar would be able to migrate from a Cassandra instance that is already dead and cannot recover. This is a scenario that is possible where Sidecar should still be able to migrate to a new instance. Alternatively, Cassandra itself could have some flag t
