A MySQL Christmas present - Libdrizzle 5.1.0

Brian Aker and I have been working hard in the last few weeks to give you a great Christmas present, Libdrizzle 5.1.0.  The MySQL compatible, BSD licensed C connector (so static compiling with commercial software gets the thumbs up!).

The latest changes include:
  • A server-side prepared statement API
  • Improved binary log API
  • An example binary log remote retrieval utility using the binlog API called "drizzle_binlogs"
  • A new build system, DDM4 which is used by Gearman and Memcached
  • Many bugs fixes
The source and manuals can be found on the Launchpad downloads page.  Please enjoy, feel free to file bugs, questions and hack on code on our Launchpad page.  Happy holidays to all!

Libdrizzle Redux 5.0-alpha1 Released!

Over the past few months I have been spending my spare time on a new project.  A new version of libdrizzle which is much simpler to use and with many new features.  Today the first version of this MySQL compatible client is released, called Libdrizzle Redux.

Why 5.0?  Because Libdrizzle 1.0 and 2.0 have already been released, in packaging versions 3.0 and 4.0 used as API revisions.  So 5.0 is the fresh start.

Main Features

These are the main features of the library:

  • A BSD licensed MySQL compatible C connector, so you can statically link it with commercial software
  • A simplified API compared to Libdrizzle.  No more confusion over whether the client or library should be allocating/freeing.  There isn't a big difference to the MySQL C API for most things.
  • New documentation, PDF for now web based coming soon.
  • A new binlog reading API.  This can connect as a MySQL slave or mysqlbinlog client and get each event from the binary log.

Differences from Libdrizzle

Whilst based on Libdrizzle, Libdrizzle Redux has had an overhaul:

  • The API is a little different from the older Libdrizzle library, for the most part it has been simplified
  • The server-side API has been stripped out, this is now a client-only connector
  • The new Binlog API
  • Improved documentation

Still to Come

These is still a lot of work to do.  There are several features I want to get in over the next 6 months and improve the features we already have.  Some example of the improvements needed are:

  • Improvements to documentation with better examples and a breakdown of the explanation of the examples and how they work
  • More tests!  Testing against more platforms too
  • A different build system.  I used CMake for now for RAD purposes, Brian Aker is already working on switching this out for an autotools based system.
  • Server-side prepared statement support
  • Several new client projects using this library

This is a fully open source project, so anyone can come along and hack on it.


You can download it now from Launchpad along with the documentation.  The download page is here.

Slides for Connectors Talk

I could not find a way to upload my slides for today's talk entitled "MySQL Compatible Open Source Connectors" on the Percona Live website so the PDF can be viewed on Slideshare.  Enjoy!
