March 2025 project status update

What happened last month? *New PMC members and committers, that's what.* We welcomed *three* new people to the PMC in Feb: Jeremiah Jordan, Caleb Rackliffe, and Ekaterina Dimitrova. We're the better for all three of them being here with us; thank you all for your hard work over the years and de

Re: [DISCUSS] CEP-36: A Configurable ChannelProxy to alias external storage locations

Because an earlier reply hinted that mounting a bucket yields "terrible results". That has moved the discussion, in my mind, practically to the place of "we are not going to do this", to which I explained that in this particular case I do not find the speed important, because the use cases you want

Re: [UPDATE] CEP-37

Thank you for the update Jaydeep. Very excited to see the progress here. I’m removed the internal status of our deployment of it now but from the JIRAs, meetings, and other conversations my impression is this feature has been heavily tested and is production grade. Jordan On Fri, Mar 7, 2025 at 1

Re: [DISCUSS] CEP-36: A Configurable ChannelProxy to alias external storage locations

I too initially felt we should just use mounts and was excited by e.g. Single Zone Express mounting. As Cheng mentioned we tried it…and the results were disappointing (except for use cases who could sometimes tolerate seconds of p99 latency. That brought me around to needing an implementation we ow

We happen to have some very informed engineers discussing Sidecar and the many things you can do with it at Cassandra Forward. Come check out the talk and give them a shout-out! https://www.datastax.com/events/cassandra-forward-march-2025 Congrats on the release! On Fri, Mar 7, 2025 at 10:44 AM B

1. Just a quick reminder that CASSANDRA-18196 is where we had been tracking this previously with respect to things like the feature flag ( CASSANDRA-18195 ), etc. I'm not su

Re: Dropwizard/Codahale metrics deprecation in Cassandra server

As long as operators are able to use all the OTel tooling, I'm happy. I'm not looking to try to decide what the metrics API looks like, although I think trying to plan for 15 years out is a bit unnecessary. A lot of the DB will be replaced by then. That said, I'm mostly hands off on code and you

Re: [DISCUSS] CEP-36: A Configurable ChannelProxy to alias external storage locations

Supporting a filesystem mount is perfectly reasonable. If you wanted to use that with the S3 mount, there's nothing that should prevent you from doing so, and the filesystem version is probably the default implementation that we'd want to ship with since, to your point, it doesn't require additiona

Re: [DISCUSS] CEP-36: A Configurable ChannelProxy to alias external storage locations

The only way I see that working is that, if everything was in a bucket, if you take a snapshot, these SSTables would be "copied" from live data dir (living in a bucket) to snapshots dir (living in a bucket). Basically, we would need to say "and if you go to take a snapshot on this table, instead of

Re: [DISCUSS] CEP-36: A Configurable ChannelProxy to alias external storage locations

Nobody is saying you can't work with a mount, and this isn't a conversation about snapshots. Nobody is forcing users to use object storage either. You're making a ton of negative assumptions here about both the discussion, and the people you're having it with. Try to be more open minded. On Fr

Re: CEP-15 Update

I would love to have my questions answered and see some graphs I don’t think those are unreasonable asks nor do they take away from the awesome work done. I was suggesting 1-2 weeks for folks to have the opportunity to produce that data if the original authors didn’t have time. I also don’t think t

Re: [DISCUSS] AWS IAM-based client authentication

Joel, thanks for reaching out. This sounds interesting, I bet there are many who would benefit from IAM-based authentication. If you haven't yet, could you request a Jira account? Someone will be able to approve it almost immediately if you don't have one yet. https://selfserve.apache.org/jira-

Re: CEP-15 Update

I defer to the judgement of the folks that are most impacted by it - ones that are in the code, working on the next release. If you all think it's good to merge, then I am 100% in support of it. I suspect merging will help get it out faster, and I don't see any future in which we don't ship this

3.5 years is an incredible amount of time and work; it really is significant and thanks to everyone involved for the investment of time and energy. We have a rocky history with large, disruptive contributions in the past that have either blocked forward progress post-merge (CASSANDRA-8099), or l

Re: [DISCUSS] CEP-36: A Configurable ChannelProxy to alias external storage locations

BTW, snapshots are quite special because these are not "files", they are just hard links. They "materialize" as regular files once underlying SSTables are compacted away. How are you going to hardlink from local storage to an object storage anyway? We will always need to "upload". On Fri, Mar 7, 2

Re: [DISCUSS] CEP-36: A Configurable ChannelProxy to alias external storage locations

Jon, all "big three" support mounting a bucket locally. That being said, I do not think that completely ditching this possibility for Cassandra working with a mount, e.g. for just uploading snapshots there etc, is reasonable. GCP https://cloud.google.com/storage/docs/cloud-storage-fuse/quickstar
