[Maria-developers] MariaDB 5.5.21
All, I've uploaded the MariaDB 5.5.21-beta packages to the primary mirror and within a few hours the files will be distributed to all of the mirrors. Over the past couple of weeks I've added several items to the release notes page for 5.5.21 and today I created the changelog page. The pages are here: http://kb.askmonty.org/en/mariadb-5521-release-notes http://kb.askmonty.org/en/mariadb-5521-changelog Once the files are distributed I will update the pages and add in the download links and remove the "unreleased" banners from the pages linked to from the release notes page. I will also send out an announcement email, and post announcements to twitter, FB, G+, and so on as usual. Please let me know ASAP if there is anything which is not on the release notes page which should be (or jump in and add it). Thanks. -- Daniel Bartholomew MariaDB - http://mariadb.org Monty Program - http://montyprogram.com AskMonty Knowledgebase - http://kb.askmonty.org
Wasn't too much copy-paste done? http://kb.askmonty.org/en/mariadb-5520-release-notes reads "This is the first 5.5-based release .." Also http://kb.askmonty.org/en/mariadb-5521-release-notes reads "This is the first 5.5-based release .." I do not understand how 5.5.21 can be "the first" if 5.5.20 also is (but there are lots of things in this World I do not claim to understand). As far as I can see it is the *second* 5.5-based MariaDB release. -- Peter -- Webyog On Thu, Mar 15, 2012 at 20:30, Daniel Bartholomew <dbart@montyprogram.com>wrote:

I knew about that paragraph, but for some reason I thought I had made the necessary updates to it and I hadn't. I've updated it.

this is the first release to feature the new threadpool. - link to the documentation : http://kb.askmonty.org/en/thread-pool-in-mariadb-55 - link to preliminary benchmarks : http://kb.askmonty.org/en/threadpool-benchmarks . NOTE: Axel ran his own benchmarks recently too, and will probably blog/publish them soon. The throughput curves will be similar as far as I can tell. - I added some time ago to "What is new in 5.5" Significantly improved for efficiency new thread pool , comparable in functionality to the closed source feature in MySQL Enterprise NOTE: pool-of-threads is now default scheduler on Windows Vista+ , so this is a change our users should be aware of . I did not made it default on Unixes (even if we had good benchmarks) yet, because Linux users are picky, and Monty objected to do it just yet , and it had more own coding than Windows case(where we rely on OS threadpooling functionality). So Unix implementation should probably be better tested for corner cases in the field, before it could be declared overall much better. Can you add essence of the above to the release notes? Thanks, Wlad
Hi, Daniel! On Mar 15, Daniel Bartholomew wrote:
I've quickly glanced through the changelog to see if anything deserves to be mentioned in release notes. Here's the list: * Updated SphinxSE * LIMIT ROWS EXAMINED * INSTALL SONAME - http://kb.askmonty.org/en/install-soname * "extended keys" support for XtraDB and InnoDB * new thread pool (with a link to benchmarks?)
