Posted by Artem Russakovskii on April 15th, 2008 in Databases

  • Speaker: Mikael Ronstrom, PhD, the creator of the Cluster engine
  • Explains the cluster structure
  • Aspects of performance
    • Response times
    • Throughput
    • Low variation of response times
  • Improving performance
    • use low level API (NDB API), expensive, hard
    • use new features in MySQL Cluster Carrier Grade Edition 6.3 (currently 6.3.13), more on this later
    • proper partitioning of tables, minimize communication
    • use of hardware
  • NDB API is a C++ record access API
    • supports sending parallel record operations within the same transaction or in different transactions
    • asynchronous and synchronous
    • NDB kernel is programmed entirely asynchronously
  • Looking at performance
    • Fire synchronous insert transactions – 10x TCP/IP time cost
    • Five inserts in one synchronous transaction – 2x TCP/IP time cost
    • Five asynchronous insert transactions – 2x TCP/IP

    • …

Updated: January 4th, 2009

Attention: Apparently since the release of 5.1.25, cluster is packaged separately. I need to do some reading and research first and then update the tutorial with the latest info.

Here are some quick links for now: http://blogs.mysql.com/kaj/2008/05/23/mysql-clusters-improved-release-model/, http://johanandersson.blogspot.com/2008/05/mysql-cluster-62-officially-released.html, http://blogs.sun.com/theaquarium/entry/improved_release_model_for_mysql.

This article contains my notes and detailed instructions on setting up a MySQL cluster. After reading it, you should have a good understanding of what a MySQL cluster is capable of, how and why it works, and how to set one of these bad boys up. Note that I'm primarily a developer, with an interest in systems administration but I think that every developer should be able to understand and set up a MySQL cluster, at least to …
