The binary version for MySQL Cluster 7.1.8 has now been made available at http://www.mysql.com/downloads/cluster/

This post follows on the previous post on SELECT performance. In this post I want to show three things:

1. How many single row UPDATEs per second you can do on on a Cluster with two data nodes (updating 64B data by the PRIMARY KEY, no batching)
   
2. Show how MySQL Cluster scales with threads and mysql servers
3. How ndb_cluster_connection_pool affects performance

Next post will be what happens to INSERTs.

Setup

• two data nodes
• one to four mysql servers
• interconnected with Gig-E (single NIC)
  

deployed on six computers (of varying quality, but not really modern, see below). www.severalnines.com/bencher was co-located with each mysql …

MySQL Cluster in iBooks

MySQL documentation has now been made available in ePub format (fetch the MySQL Cluster versions from http://dev.mysql.com/doc/index-cluster.html ). This format is intended for various book readers.

I’ve tried it on 2 iPhone applications; Apple’s iBooks and the iPhone version of Stanza. The documents render well in both applications but as with most reference books you get the best results if you reduce the font size so that you get more on the screen at once.

With both applications, you can add the books through iTunes but Stanza also has the advantage that if you browse to the document in Opera on the iPhone then it gives you the option of opening it in Stanza – cutting out the need to use iTunes. I also …
