NoSQL Java API for MySQL Cluster: Questions & Answers
Employee_Team +3 Vote Up -0Vote Down

The MySQL Cluster engineering team recently ran a live webinar, available now on-demand demonstrating the ClusterJ and ClusterJPA NoSQL APIs for MySQL Cluster, and how these can be used in building real-time, high scale Java-based services that require continuous availability.

Attendees asked a number of great questions during the webinar, and I thought it would be useful to share those here, so others are also able to learn more about the Java NoSQL APIs.

Hacking the Jenkins BZR plugin
+2 Vote Up -0Vote Down

For Drizzle and for all of the projects we work on at Percona we use the Bazaar revision control system (largely because it’s what we were using at MySQL and it’s what MySQL still uses). We also use Jenkins.

We have a lot of jobs in our Jenkins. A lot. We build upstream MySQL 5.1, 5.5 and 5.6, Percona Server 5.1, Percona Server 5.5, XtraBackup 1.6, 2.0 and 2.1. For each of these we also have the normal trunk builds as well as …

Under the Hood with Connector/J's "rewriteBatchStatements=true"
Employee +2 Vote Up -0Vote Down

My old post ( on the performance gains from batch rewritten statements gets regurgitated in various forums, and conference sessions, and often people miss the nuances of it.

Under the hood, what is happening with this feature is the following:

(1) The driver attempts to detect that the SQL being prepared is an INSERT. We (on purpose) don‘t ship a full-fledged parser in the driver, so this works 95% of the time. For the other 5%, you‘re out of luck unless you …

Zend CE has a Worm
+0 Vote Up -1Vote Down

After updating the AVGFree virus definitions, I was surprised to find that Zend CE (Community Edition) 4.0.6 had a worm in the JavaServer.exe file. There was greater surprise when Zend CE 5.3.9 (5.6.0-SP1) also had the same worm.

This is the message identifying the worm (click on it to see a full size image), and you can read about this particular worm on the Mcafee site:

Oracle CSV Imports
+0 Vote Up -0Vote Down

The first step in creating an effective import plan for comma-separated value (CSV) files is recognizing your options in a database. There are several options in an Oracle database. You can read the file with Java, C/C++, C#, PL/SQL (through the UTL_FILE package), PHP, Perl, or any other C-callable programming language; or you can use SQL*Loader as a standalone utility or through externally managed tables (known as external tables). The most convenient and non-programming solution is using external tables.

Adopting external tables as your import solution should drive you to consider how to manage the security surrounding this type of methodology. Host …

Connector/J extension points – Load Balancing Strategies
Employee +2 Vote Up -0Vote Down

A fourth and final Connector/J extension point I covered in my JavaOne and Silicon Valley Code Camp presentations is load-balancing strategies.  This exists in order to allow you to define behavior for balancing load across multiple back-end MySQL server instances.  MySQL Connector/J’s load-balancing implementation is a simple internal connection pool.  What appears to your application as a single Connection object can actually have multiple physical connections to MySQL servers underneath (one per …
