Understanding Bulk Index Creation in InnoDB (and innodb_sort_buffer_size)
+0 Vote Up -0Vote Down

In a previous post, I presented an Unexpected Memory Consumption for Bulk Index Creation in InnoDB.  This was triggered by an increased innodb_sort_buffer_size and as stated in another post: "the sorting algorithm does not scale well with large sort buffers".  In this post, I will present why it does not scale well and I will suggest solutions.

This post also answers feedback request for the

systemd: a revolution gets used to itself
+0 Vote Up -0Vote Down

New versions of systemd (like in Ubuntu 16.04) are able to configure pid Cgroups (ulimit -u via Cgroups) using TasksMax.

Check the commit implementing TaksMax.

    core: enable TasksMax= for all services by default, and set it to 512

    Also, enable TasksAccounting= for all services by default, too.

    See:

    http://lists.freedesktop.org/archives/systemd-devel/2015-November/035006.html

But not we’ve got silly defaults:

$ systemctl show -p TasksMax docker
TasksMax=512

I am now a member of team MariaDB
+0 Vote Up -0Vote Down

Monday I started at MariaDB working on ColumnStore. My interest in column store technology extends way back to the days as the MySQL evangelist at Kickfire, which was a compressing column store and "SQL CHIP" appliance. My initial tasks are documentation related, but I'll be helping with development, and of course testing it with Shard-Query, which is a great stress testing system.

London roadshow wrap-up, see you in Paris next week
+0 Vote Up -0Vote Down

Just a few days ago, I presented at the MariaDB Roadshow in London, and I had a lot of fun. While I had canned slides, I did know the topic intimately well, so it was good to get further in-depth. In addition, we had these MasterMind sessions, basically the place to get one-on-one time with Anders/Luisa/or me, I noticed that pretty much everyone said they were buying services afterwards (which more or less must mean the event was rather successful from that standpoint!).

In addition to that, I was happy to see that from attendee …

MySQL/MariaDB cursors and temp tables
+0 Vote Up -0Vote Down

In MariaDB and MySQL, cursors create a temporary table.

Does this statement deserve a whole blog post? Apparently not. However, in some cases one does not expect a temporary table to be created:

  • SELECT ... FOR UPDATE: An exclusive lock is created, yes, but you still read data from a temporary table.
  • SELECT FROM a temporary table: you are reading from a temporary tables, yes, but an internal temporary table is created anyway.
  • Impossible WHERE and LIMIT 0.

A quick example:
