Load-balanced JDBC Tip for GlassFish Deployments
Employee +3 Vote Up -0Vote Down

Having supported a number of successful load-balanced JDBC applications using MySQL Cluster and MySQL Connector/J over the years, I’ve found a few problems that are unique to specific Java app servers.  A recent customer inquiry reminded me of a GlassFish-specific issue, and the Connector/J connection property we introduced to help solve it.  I thought it might be useful to document this here for any GlassFish users looking to deploy a load-balanced JDBC application with MySQL (Cluster or multi-master replication).

MySQL Cluster Performance Best Practices: Q & A
Employee_Team +4 Vote Up -0Vote Down

With its distributed, shared-nothing, real-time design, MySQL Cluster (http://www.mysql.com/products/cluster/) has attracted a lot of attention from developers who need to scale both read and write traffic with ultra-low latency and fault-tolerance, using commodity hardware. With many proven deployments (http://www.mysql.com/customers/cluster/) in web, gaming, telecoms and mobile use-cases, MySQL Cluster is certainly able to meet these sorts of requirements.

But, as a distributed database, developers do need to think a little differently about data access patterns along with schema and query optimisations in order to get the best possible performance.
