SET GLOBAL sql_log_bin - We need your feedback!
Employee +2 Vote Up -0Vote Down

Jeremy Cole recently blogged about the feature SET GLOBAL sql_log_bin. In his blog post, Jeremy suggested that there is no strong use-case for this feature, and that it is too easy to run accidentally (i.e. SET GLOBAL instead of SET [SESSION]). The result of this incorrect usage is that slaves will drift out of sync from masters.

We discussed Jeremy's request in the MySQL team, and we agree that the syntax should produce an error in MySQL 5.7. However, we have not yet determined which steps should be taken for MySQL 5.5 and MySQL 5.6. The two proposals we would like to float are:

  • The statement SET GLOBAL sql_log_bin=N produces a warning.
  • The statement SET GLOBAL sql_log_bin=N produces an error.

    Restarting production database servers with gigabytes of memory is difficult. It can lead to cold caches and other operational complexities.

    The InnoDB team is looking to make improvements so that restarting MySQL is required as little as possible. Please help them out by answering which configuration settings you are most eager to see made dynamic.

    Hello all,

    I hope you're doing well. After the successful event last year it's a no brainer to arrange another community dinner when we're all together again in London this November.

So this year join the MySQL community again for a bite to eat and a beverage or two and discuss life, love and data.

      MariaDB moves development to Github
      +0 Vote Up -0Vote Down

      Today marks a milestone in terms of the MariaDB project – going forward, the MariaDB project plans to use Github and git for source code management. The migration happens from Launchpad and the bzr tool.

      The 10.1 server development (under heavy development now) will happen on Github. You can check it out here: https://github.com/MariaDB/server. Feel free to watch, star or even fork the code, and send us contributions!

      Previous maria-captains should now provide their Github IDs so that they can be accorded similar status. Send the IDs to the maria-developers mailing list.

      MySQL soon to store system tables in InnoDB
      Employee +5 Vote Up -0Vote Down

      In the MySQL team, we are changing the system tables currently located in the mysql schema from MyISAM to InnoDB.

      Looking at this historically:

      • MyISAM was the default storage engine up until MySQL 5.5.
      • In 5.5 almost 4 years ago, the default storage engine changed to InnoDB, however system tables used for features such as storing privileges and timezones remained as MyISAM.

      Unlike MyISAM, InnoDB is an ACID compliant storage engine, with the behaviour that once a transaction commits, modifications are able to survive power-loss or other failures. This is a solid foundation to build applications on, since developers will need to handle fewer failures. To use an example:

    • Customer places an order
    • A confirmation email is sent
    • Power is lost
    • Without durability, (2) could occur with no record of (1)

      Proposal to deprecate COM_REFRESH packet
      Employee +0 Vote Up -0Vote Down

      In the MySQL team we are proposing to deprecate the COM_REFRESH packet in favor of specific queries to execute FLUSH commands. To provide a bit of context:

      • The MySQL server protocol allows for clients to speak API commands via both a query and binary protocol interface. The set of the API commands can be seen in the MySQL Client/Server Protocol internals documentation, or very simply as they appear in a single switch statement:
        # ./sql/sql_parse.cc:1009 (simplified view)
          switch (command) {
          case COM_REGISTER_SLAVE:
            /* do stuff */
          case COM_QUERY:
            /* parse query, do stuff */
          case COM_REFRESH:
           /* equivalent to running a FLUSH command */

      Proposal to deprecate the old password format
      Employee +1 Vote Up -0Vote Down

      Improving security has been a high priority for MySQL 5.7. To give you an idea of some of the changes to date, I recommend reading Todd Farmer's blog: Redefining --ssl option, Password expiration policy, AES256 encryption.

      In MySQL 5.7, we are also proposing to remove the 'old' format for saving passwords. To provide some historical context:

      • The old password format is a 16-byte hash and considered to be cryptographically weak. Code appears online (I won't link to it) which allows the hash

      GUUG Frühjahrsfachgespräch 2014: CfP ends on May 31st!

      Calling for all mysql_install_db feature requests
      Employee +2 Vote Up -0Vote Down

      mysql_install_db is the program that is responsible for bootstrapping a fresh copy of MySQL and making sure all of the system tables are setup correctly. This program is usually invoked by other programs as part of installation, but in the case of .tar.gz downloads will need to be executed manually.

      As part of our ongoing efforts to refactor and improve MySQL, we are looking at converting mysql_install_db from its current Perl script to a program written in C++. The aim of this change is to reduce external dependencies (Perl + a set of modules) and improve our cross-platform experience.

      We plan for this transition to be mostly function neutral, but are open to feature requests for additional improvements as well.

      Have you worked in packaging MySQL?
      Do you have any suggestions on how mysql_install_db can be improved?
      Please leave a comment, or get in touch!

      MySQL defaults evolution
      +1 Vote Up -0Vote Down

      MySQL, the original brand, the one developed by the MySQL team at Oracle, is steadily evolving. You can feel it if you try every new release that comes out of the milestone release cycle. Or even if you don’t try all of them, just testing a release once in a while gives you something to think about.

      The engineers at Oracle are trying hard to improve the defaults. If you are the out-of-the-box type, and just install the new version on top of the previous one, leaving the same setup in place, you may be up for a for a few surprises. It’s the marketing, see? They tell you that just by replacing your old MySQL (5.1 or 5.5) with MySQL 5.6 you get 30% to 70% performance improvement. Which happens to be true, not only because the server is better, but also because they have changed the defaults. However, this change in

      We're looking to improve PlanetMySQL
      Employee +1 Vote Up -0Vote Down

      We are looking for community feedback on how improve the Signal-to-Noise ratio of PlanetMySQL, and reduce the amount of irrelevant and off-topic posts.

      To give you a sense of where we are at today, we currently approve most [all?] blogs for aggregation, provided they have some existing technical content. We then apply a naive regular expression to make sure that all posts are on topic (MySQL).

      The sorts of ideas we are looking for are:

      • What content are you interested in seeing more or less of?
      • What posts do you deem as acceptable or unacceptable?
      • Do we need to change the balance between technical, marketing, event, or business-related posts?
      • Are there any tools or features we could introduce to better serve readers and authors?

      If you have any suggestions - please send them my way!

      Proposal to deprecate mysqlhotcopy
      Employee +0 Vote Up -0Vote Down

      In the MySQL team, we are considering deprecating the mysqlhotcopy utility. To provide some background, here is an excerpt from the MySQL manual:

      mysqlhotcopy is a Perl script that was originally written and contributed by Tim Bunce. It uses FLUSH TABLES, LOCK TABLES, and cp or scp to make a database backup. It is a fast way to make a backup of the database or single tables, but it can be run only on the same machine where the database directories are located. mysqlhotcopy works only for backing up MyISAM and ARCHIVE tables. It runs on Unix.

      And now let me explain the motivations leading to our proposal:

      • The name implies that this utility will work for 'MySQL' and is hot, but actually neither are true:
      • Only MyISAM and ARCHIVE
