MariaDB 10.1.2 Overview and Highlights

Saturday, January 17th, 2015

MariaDB 10.1.2 was recently released, and is available for download here:

https://downloads.mariadb.org/mariadb/10.1.2/

This is the third alpha release of MariaDB 10.1, so there are still a lot of new changes, functionalities added, defaults changed, and many bugs fixed (I counted 117, which is *way* down from the 637 fixed in 10.1.1). Since it’s alpha, I’ll only cover the major changes and additions, and omit covering general bug fixes (feel free to browse them all here).

To me, these are the highlights of the new features:

MariaDB 10.0.15 Overview and Highlights

Friday, January 16th, 2015

MariaDB 10.0.15 was recently released, and is available for download here:

https://downloads.mariadb.org/mariadb/10.0.15/

This is the sixth GA release of MariaDB 10.0, and 16th overall release of MariaDB 10.0.

This release has an important InnoDB/XtraDB fix, a new addition, security enhancements (and improvement) – all related to yaSSL, so be sure to check out these fixes if you’re running MariaDB 10.0, and not up to 10.0.15 yet. (MariaDB 10.0 is the current stable series of MariaDB. It is an evolution of the MariaDB 5.5 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6.)

Here are the main items of note:

  1. This release fixes a serious bug in InnoDB and XtraDB that sometimes could cause a hard lock up of the server (MDEV-7026)
  2. This is the first release that includes Mroonga full-text search storage engine.
  3. When compiled with OpenSSL, MariaDB now supports TLSv1.2 protocol. Limit it to TLSv1.2 ciphers only with –ssl_cipher=TLSv1.2. Limit it to SSLv3 ciphers with –ssl-cipher=SSLv3. RPM and DEB packages from MariaDB.org are built with OpenSSL, others (for Windows and generic Linux) are built with yaSSL.
  4. Fixes for the following security vulnerabilities:
  5. Bundled PCRE is upgraded to 8.36
  6. InnoDB upgraded to 5.6.21
  7. XtraDB upgraded to 5.6.21-70.0
  8. TokuDB upgraded to 7.5.3
  9. SphinxSE upgraded to 2.2.6
  10. Updates to the CONNECT handler including:
  11. We now offer openSUSE repos, see the repository configuration tool for details on how to use it.

Given the severe InnoDB/XtraDB bug, if you’re running a prior MariaDB 10.0 version, I’d recommend upgrading (assuming you’re using InnoDB). Likewise, if you’re using SSL. And then there were a number of fixes to other fixes for TokuDB, CONNECT, and Sphinx, so if you’re using those technologies, you may want to consider upgrading as well.

https://downloads.mariadb.org/mariadb/5.5.41/

This is a maintenance release, and so there were not too many changes, *but* please take notice as there are 2 very important bug fixes:

Thus if you’re running pre-5.5.41 and have encountered, or even if you may be prone to, either bug #7026 or #7100, you should plan to upgrade.

Discussing the innodb_log_block_size variable

Tuesday, November 11th, 2014

Not a ground-breaking post here, but if you are interested in knowing more about the innodb_log_block_size variable, or if you use SSD cards and/or large InnoDB log files on ext4, then this is for you.

I’d read about it before briefly before, but didn’t give it too much thought until I ran across the following entry in an error log the other day:

InnoDB: Warning: innodb_log_block_size has been changed
from default value 512. (###EXPERIMENTAL### operation)

This got me wanting to know more.

Basically, this variable changes the size of transaction log records. Generally, the default of 512 is a good value. However, it has been found that setting it to 4096 has been beneficial when using SSD cards. (Note that while it is possible to set this to a value other than 512 or 4096, those are currently the only 2 values that make sense to use.)

Also, it has been found that 4096 is the best setting if you run ext4 along with innodb_flush_method=ALL_O_DIRECT (note both innodb_log_block_size and ALL_O_DIRECT are specific to XtraDB/XtraDB+; read: MariaDB and Percona server).

What is ALL_O_DIRECT and when it is useful?

“ALL_O_DIRECT: use O_DIRECT to open both data and log files, and use fsync() to flush the data files but not the log files. This option is recommended when InnoDB log files are big (more than 8GB), otherwise there might be even a performance degradation.”

http://www.percona.com/…/innodb_io.html#innodb_flush_method

Thus if you’re running large InnoDB log files (8G+) on ext4, you may want to consider ALL_O_DIRECT, and because you’re on ext4, you should set innodb_log_block_size=4096, the default log-block-size in ext4, in order to avoid the unaligned AIO/DIO warnings.

Likewise, if running with SSD cards, you’d likely see a performance improvement with innodb_log_block_size=4096 also.

If interested, there is a bit more about the innodb_log_block_size option here:

MariaDB 10.1.1 Overview and Highlights

Saturday, October 25th, 2014

MariaDB 10.1.1 was recently released, and is available for download here:

This is the second alpha release of MariaDB 10.1, so there are a lot of new changes and functionalities added, and many, many bugs fixed (I counted 637). Since it’s alpha, I’ll only cover the major changes and additions, as there are a lot of great new features, and omit covering any of the bug fixes (feel free to browse them all here).

To me, these are the highlights of the new features:

And here are other new features of note:

MariaDB 10.0.14 Overview and Highlights

Tuesday, October 7th, 2014

MariaDB 10.0.14 was recently released, and is available for download here:

https://downloads.mariadb.org/mariadb/10.0.14/

This is the fifth GA release of MariaDB 10.0, and 15th overall release of MariaDB 10.0.

This is primarily a bug-fix release. (MariaDB 10.0 is the current stable series of MariaDB. It is an evolution of the MariaDB 5.5 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6.)

Here are the main items of note:

  1. TokuDB upgraded to 7.5.0
  2. XtraDB upgraded to 5.6.20-68.0
  3. InnoDB upgraded to 5.6.20
  4. Spider upgraded to 3.2.11
  5. SphinxSE upgraded to 2.1.9
  6. The Feedback plugin now includes statistics on collation usage.
  7. Error log has a flood protection that is activated after 10 identical unsafe warnings and disables them for the next 5 minutes.
  8. Many fixes and optimizations for the Power8 platform.
  9. As per the MariaDB Deprecation Policy, this will be the last release of MariaDB 10.0 for both Ubuntu 13.10 “Saucy” and Mint 16 “Petra”.
  10. With the recent release of CentOS 7 and RHEL 7, we are pleased to now provide packages for both distributions. Instructions for how to enable the repositories can be found by visiting the “Installing MariaDB with YUM” page and the repository configuration tool.
  11. Crash in GROUP_CONCAT(IF () ORDER BY 1) (MDEV-6743)
  12. Server crashes in my_hash_first if shutdown is performed when FLUSH LOGS is running (MDEV-6616)
  13. Slave replicating using GTID doesn’t recover correctly when master crashes in the middle of transaction (MDEV-6462)
  14. MariaDB crash on Power8 when built with advance tool chain (MDEV-6450)

As always, it’s great to see all of the fixes alone from TokuDB, XtraDB, InnoDB, Spider, and Sphinx (and thus if you’re relying on any of these technologies, I would consider upgrading). The Power8 enhancements are very nice to see also! (If you’re running Power8 and looking for performance improvements, then you should definitely look into upgrading.) The crash fixes are mostly obscure, but double-check them, just in case they might affect you currently, and if so, then plan to upgrade.
