The host defined in the log (10.112.50.145) isn't even one of the local ips of the hosts in the cluster or my severalnines cluster control ip. It keeps incrementing 2 ports and retrying every 5-6 seconds. It's showing the same thing on two nodes in us-east, but nothing in the error log on the us-west-1 node.

[Maria-discuss] aria checksum
by Scott Feldstein 30 Apr '13

30 Apr '13

Hi, I have data which I want to store in the aria storage engine, the data is inserted then never updated or deleted, although the table could be truncated. This data could potentially be replicated in production. The data is inserted in parallel and once the table reaches a certain capacity data is no long inserted into it. My question is, would I want to turn on the checksum for this data? And, if yes, should I use table checksum or page checksum? What are the advantages / disadvantages of this? I tried searching docs and couldn't find a breakdown so if someone could answer this or point me to a doc or discussion that would be great. Right now I am using DYNAMIC row format since I want the smallest footprint possible. thanks, Scott

[Maria-discuss] New server, switch to MariaDB, different versions
by Tanstaafl 27 Apr '13

27 Apr '13

Hello, My current (8 yr old bare metal) server is currently running mysql 5.1.62, with just a couple of very small databases: postfixadmin and roundcube I am setting up a shiny new virtualized (ESXi host) server, that now has MariaDB 5.5.30 on it... My question is, can I do a dump from my old server running mysql 5.1.62, then restore that dump to my new server running MariaDB 5.5.30, run mysql_upgrade, and have any kind of reasonable expectation of it working? I'd rather not update the current (production) server to MariaDB (I'm gunshy when it comes to major changes on a production system). If not, then my other option would be to downgrade MariaDB on the new server to 5.1.66... but again, I'd rather not do that if it isn't necessary. Thanks - I'm really looking forward to saying goodbye to mysql (for political reasons, the software itself has served me well these 8 years, it's just too bad that they got bought by Oracle)... Charles

[Maria-discuss] MariaDB 10.0.2-alpha now available
by Daniel Bartholomew 24 Apr '13

24 Apr '13

The MariaDB project is pleased to announce the immediate availability of MariaDB 10.0.2. This is an alpha release. MariaDB 10.0 is the development version of MariaDB. It is built on the MariaDB 5.5 series with backported features from MySQL 5.6 and entirely new features not found anywhere else. This is the third 10.0-based release, and we are releasing it now to get it into the hands of any who might want to test it. Not all features planned for the MariaDB 10.0 series are included in this release. Additional features will be pushed in future releases. See the release notes and changelog for details on what is new in this release. Do not use alpha releases on production systems. - - Links - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - MariaDB 10.0.2 Alpha - Release Notes: http://kb.askmonty.org/en/mariadb-1002-release-notes - Changelog: http://kb.askmonty.org/en/mariadb-1002-changelog - Downloads: http://downloads.mariadb.org/mariadb/10.0.2 Overview of MariaDB 10.0: http://kb.askmonty.org/en/what-is-mariadb-100 APT and YUM Repository Configuration Generator: http://downloads.mariadb.org/mariadb/repositories/ - - User Feedback plugin - - - - - - - - - - - - - - - - - - - - - - - MariaDB includes a User Feedback plugin.

However, when a distribution or OS stops receiving security and other updates it becomes difficult to freely provide packages for that platform. In such cases, our policy is to deprecate that platform and stop providing binary packages for it. Accordingly, this will be the final release of MariaDB 10.0 for the following distributions: - Ubuntu 8.04 LTS "Hardy" - Ubuntu 11.10 "Oneiric" If your chosen Linux Distribution or Operating System is deprecated, packages or support are not completely unavailable. Companies such as SkySQL, Monty Program, and others provide support for all versions of MariaDB back to even very old MySQL versions. This includes packaged binaries. Contact them for more details.

[Maria-discuss] TokuDB + MariaDB: libjemalloc is important
by Colin Charles 23 Apr '13

23 Apr '13

Hi! Continuing on the interest in libjemalloc, and how we have a thread started on in, especially since Percona is building their server going forward using it (see: https://lists.launchpad.net/maria-discuss/msg00788.html) we've also had requests from Team Tokutek, that TokuDB also requires us building with jemalloc for a good experience. I'm adding Tim Callaghan to the discussion, as TokuDB has been building & releasing with it for over a year The other Callaghan who's on this list, Mark, has also made posts about jemalloc: https://www.facebook.com/MySQLatFacebook/posts/486784224710172 & https://www.facebook.com/notes/mysql-at-facebook/using-jemalloc-to-fix-a-pe… Shall we think about using a different malloc implementation? LD_PRELOAD may be the only option we have to change... (oh and test, benchmark, etc.) cheers, -colin -- Colin Charles, http://bytebot.net/blog/ | twitter: @bytebot | skype: colincharles MariaDB: Community developed. Feature enhanced. Backward compatible.

[Maria-discuss] Fedora test day for replacing MySQL with MariaDB
by Colin Charles 19 Apr '13

19 Apr '13

Hi all, By now you must know of the movement to replace MySQL with MariaDB in Fedora-land (http://fedoraproject.org/wiki/Features/ReplaceMySQLwithMariaDB) One important thing is to ensure that MariaDB is a drop-in replacement. Fedora is a fast-moving high quality Linux distribution, so their focus aims are to ensure that MariaDB and MySQL are compatible, data can be migrated easily and there are minimal/no upgrade issues (and if so, they need to be documented) This is why on 30 April 2013, there is a Fedora test day dedicated to this very important task: http://fedoraproject.org/wiki/Test_Day:2013-04-30_MariaDB I plan to be on IRC for as long as humanly possible on #fedora-test-day (freenode) and will be watching the process closely. If you would like to participate, this is naturally welcome to help new MariaDB users Thanks! cheers, -colin -- Colin Charles, http://bytebot.net/blog/ | twitter: @bytebot | skype: colincharles MariaDB: Community developed.

[Maria-discuss] jemalloc used in Percona Server 5.5.30
by Colin Charles 13 Apr '13

13 Apr '13

Hi! Steve Meyers, a MariaDB user, is quite excited to see that libjemalloc is used for Percona Server 5.5.30 (http://www.stevemeyers.net/2013/04/percona-server-to-ship-with-jemalloc.html) He's wondering if we'll adopt this A note from the latest release notes: "Percona Server for MySQL will now be shipped with the libjemalloc library. Benchmark showing the impact of memory allocators on MySQL performance can be found in this blogpost." Blogpost: http://www.mysqlperformanceblog.com/2012/07/05/impact-of-memory-allocators-… cheers, -colin -- Colin Charles, http://bytebot.net/blog/ | twitter: @bytebot | skype: colincharles MariaDB: Community developed.

Subject says it all We need people to sign up as mentors (http://www.google-melange.com/gsoc/homepage/google/gsoc2013) against the MariaDB project Students start opening up soon If you know of projects a student can complete in 3 months over a summer, this is the ideal place to list the task: https://kb.askmonty.org/en/google-summer-of-code-2013/ This is the first time MariaDB is going to participate. Some of you have done this in the past against MySQL or Drizzle. Big win for MariaDB this year! cheers, -colin -- Colin Charles, http://bytebot.net/blog/ | twitter: @bytebot | skype: colincharles MariaDB: Community developed. Feature enhanced. Backward compatible.
