Introducing mysqlpump
Employee_Team +1 Vote Up -0Vote Down

Starting with MySQL 5.7.8, we are shipping a new client utility called mysqlpump that performs logical backups, producing a set of SQL statements that can be run to reproduce the original schema objects and table data. The goal of mysqlpump is to have a modern utility that is extendable and has native support for parallelization. We felt that the best way to achieve this was to write an entirely …

TL;DR look at the two visualized commands below

The "smart" commands to end all commands

How MySQL-Sandbox is tested, and tests MySQL in the process
+0 Vote Up -0Vote Down

MySQL-Sandbox is a great tool for testing a new release, and in fact this is what I do when a new MySQL tarball becomes available. I don't think many people are aware of the full testing capabilities of the sandbox, though.

When you think about testing, you may just think of creating a sandbox with the new tarball, and then hammering it with your pet procedure. That works, of course, as the main purpose of MySQL-Sandbox is to allow you to do just that. There is, however, a full test suite that can tell you in a short while if your tarball is compatible with the past or not.

Cached linkbench performance for MySQL 5.7.8, 5.6, WebScale and MyRocks
+0 Vote Up -0Vote Down

This extends previous results for Linkbench to compare performance for a cached database with concurrent clients. My conclusions are:

  • InnoDB compression in the Facebook patch for MySQL 5.6 is much faster for insert-heavy workloads than the same feature in upstream 5.6 and 5.7. Too bad those changes might not reach upstream
  • InnoDB …
