Picking the Right Clustering for MySQL: Cloud-only Services or Flexible Tungsten Clusters? New webinar-on-demand

As businesses head into the cloud, it is tempting to reach for the first product that offers to make database operation as simple as punching a few buttons on a menu.  However, there’s a big difference between firing up cloud database services such as Amazon RDS for testing or development and finding a solution that can handle hundreds of millions of transactions daily. This webinar-on-demand

New Webinar on July 9th: How To Set Up SQL Load Balancing with HAProxy

June 17, 2014 By Severalnines

 

We continuously see great interest in MySQL load balancing and HAProxy, so we thought it was about time we organised a live webinar on the topic!

 

As most of your will know, database clusters and load balancing go hand in hand. 

 

Once your data is distributed and replicated across multiple database nodes, a load balancing mechanism helps distribute database requests, and gives applications a single database endpoint to connect to. 

 

Instance failures or maintenance operations like node additions/removals, reconfigurations or version upgrades can be masked behind a load balancer. This provides an efficient way of isolating changes in the database layer from the rest of the …

MaxScale 0.7.0 Overview and Highlights

MaxScale 0.7.0 was recently released (it is the 4th alpha, with the beta on the near horizon), and is available for download here.

The release contains a number of new enhancements as well as 8 bugs fixes.

Enhancements:

  1. Galera Support: Enhanced support for Galera cluster to allow Galera to be used as a High Available Cluster with no write contention between the nodes. MaxScale will control access to a Galera Cluster such that one node is designated as the master node to which all write operations will be sent. Read operations will be sent to any of the remaining nodes that are part of the cluster. Should the currently elected master node fail MaxScale will automatically promote one of the remaining nodes to become the new master node.
  2. Multiple Slave Connections: The Read/Write …

MaxScale 0.6.0 Overview and Highlights

MaxScale 0.6.0 was recently released (it is the 3rd alpha, with the beta on the near horizon), and is available for download here.

The particular release only contains 2 great additions and 2 important fixes (and note development continues with the 1.0 (GA) features, but these have not been put into this alpha version).

Important Additions:

  1. A feature-complete read/write splitting module, i.e. read and write operations are now balanced in a smarter way to master or slave servers.
  2. New client-based features, such as a version string that provides compatibility with the major connectors, the ability to connect through the root user and the use of the Unix socket when MaxScale is co-located with a client application on the same server.

Important Bug Fixes:

  1. The new parameter …
