While hard at work, it’s important to be visible so people don’t wonder if there’s anything happening… the open source development model is extremely good for this, things are just public all the time. Some may find this a source of stress or potential embarassment, but I think it’s great and overall makes for better quality code, products, and a nicer work environment.
To see what’s going on with OurDelta right now, we need to take a peek at https://code.launchpad.net/percona-patches where the Percona developers have been busy putting in lots of changes in both the 5.0.67 tree (mainly little improvements and fixes to existing patches) as well as working on the 5.1 ports of the 5.0 patches. Launchpad lets you subscribe to a particular branch, so you get notified when there’s a new commit, and see the changeset comment. That’s a very handy way to keep up to date.
For OurDelta, the first 5.1 release will very simply be when we have all the 5.0 patches working in 5.1; it’s taking a bit of time and of course it would be great if it took less time, but I think we can all agree that it’s the right thing to do. Or if you feel different, please do speak up!
For 5.0, there’s always little fixes as well as some new patches… so how often to do a build? Right now I think once every two months is decent. Again, if you feel different, please let us know! Simply join the https://launchpad.net/~ourdelta-developers list and put in your thoughts. Community participation (which I believe is the multilateral form of ‘contribution’) is really that simple. Thanks!
OpenSQL Camp 2008 has come and gone, and hooray again for Baron who came up with the idea and made most of it happen (but let’s not forget Sheeri!) Events such as these are always educational, but the most interesting stuff happens outside of the organised sessions (and this being an un-conf, they weren’t that strictly planned anyway 😉
For me (Arjen) a major chunk of the exercise was acquiring jetlag there and back with no days to spare either side, but I feel it was well worth it. I spent most of the time listening and talking with people rather than coding. It was a great opportunity to catch up with Monty, the Percona crew (Baron, Peter, Vadim, Tom, and more – there’s so many of them now!), Brian, Stewart, Jay, Pat, Eric and other Drizzlers, Sheeri, active OurDelta people like Nick and Rob, ex-Brisbanite Ronald, and of course Jim who thought he might learn something in the MVCC session (no I’m not going to explain that joke!)
The Percona patches have moved to Launchpad, so from now on they’re being developed in plain sight, available earlier for peer review, and more easily integrated into OurDelta builds. Thanks Vadim for making that happen! An excellent example of the Open Source development model – the resulting quality will be even higher! The Percona crew is also working on their end of the 5.1 porting of the patches, with priority given to the performance-related ones. OurDelta contains additional patches and features, so we have extra work anyway – all help is great and much appreciated!
OurDelta is, as stated previously, committed to doing 5.1 builds also, but we’re going to continue doing 5.0 builds for the foreseeable future as well. Most deployments are currently on 5.0, and the various enhancements in OurDelta builds provide breathing space (in terms of performance, and monitoring/tuning instrumentation) while people check out 5.1 and plan for a possible upgrade. And we’ll make sure that anything we put in 5.0 will also be available in 5.1, so that you don’t lose anything when you do upgrade. That’s our promise.
We’re currently looking at a few more platforms to build for, such as Solaris and Windows. The latter is mainly aimed at developers, who will certainly appreciate the extra info they can get out of an OurDelta build and thus make better performing applications!
Next to performance-related patches, instrumentation is and will remain a key focus for OurDelta. We want to get even more information from the server (without increasing disk I/O, contention or CPU load and yes that is possible), as it offers more breadth and depth than any external solution. And we reckon -and that’s us who deal directly with real-world deployments on a daily basis- that is well worth the extra effort!
This week saw the release of OurDelta patchset d7 build of MySQL 5.0.67, basically a cleaned-up update of the earlier (and first) OurDelta d6 build. The number of downloads/fetches within the first few hours surpassed the total number from the previous weeks.
Downloads and yum/apt-get repository fetches now always go via one of our mirrors, as obviously the main server can’t possibly handle all that attention! By default you just get sent to “somewhere on the planet”, although you can tweak your repo setup to only use specific mirrors. If you want to become a mirror for OurDelta, drop us a line and we’ll be happy to add you in; the more the merrier!
Ubuntu 8.10 Intrepid is now also supported. We welcome input on which additional platforms are desirable.
There was a podcast, where interviewer James Purser came up with an good description of what OurDelta is: “a new distro for MySQL”.
OurDelta development in the coming weeks will focus on 5.1. If you would like to get involved with this particular effort, join the ourdelta-developers group on Launchpad, and check out the recent mailing list archive. There’s more to it than just code; but getting started there is not as hard as it seems, and there’s plenty of helpful hands about!
