Oracle's expensive and complex replication makes it difficult to build cost-effective applications that move data in real-time to data warehouses (Oracle, Hadoop, Vertica) and popular databases like MySQL. Fortunately, Continuent Tungsten offers a solution.In this virtual course, you will learn how Continuent Tungsten solves problems with Oracle replication at a fraction of the cost of other

One interesting feature of MySQL, is that it supports a very large number of integer data types. From the MySQL manual:

Introduction:

To run MariaDB from Eclipse we will actually create and install the tar.gz package resulting from compilation(See Part 2) in a separate directory, this will allow us to have MariaDB cleanly installed on a separate location and so it will be also easily possible to run it independently from Eclipse.

I’m pleased to say that Continuent will be at the Hadoop Summit in San Jose next week (3-5 June). Sadly I will not be attending as I’m taking an exam next week, but my colleagues Robert Hodges, Eero Teerikorpi and Petri Versunen will be there to answer any questions you have about Continuent products, and, of course, Hadoop replication support built into Tungsten Replicator 3.0.

If you are at the conference, please go along and say hi to the team. And, as always, if there are any questions please let them or me know.

This is the third post in our MySQL Fabric series. If you missed the previous two, we started with an overall introduction, and then a discussion of MySQL Fabric’s high-availability (HA) features. MySQL Fabric was RC when we started this series, but it went GA recently. You can read the press release here, and see this blog post from Oracle’s Mats Kindahl for more details. In our previous post, we showed a simple HA setup managed with MySQL Fabric, including some basic failure scenarios. …

Getting data into Hadoop is not difficult, but it is complex if you want to load 'live' or semi-live data into your Hadoop cluster from your Oracle and MySQL databases. There are plenty of solutions available, from manually dumping and loading to the good and bad sides of using a tool like Sqoop. Neither are easy and both prone to the problems of lag between the moment you perform the dump and

Running MySQL in the cloud offers many benefits, including extremely fast provisioning and deployment, managed security, and (mostly) easy operations. But nothing comes for free, and as with all things on this wonderful planet, those benefits come with certain limitations. Until recently, one of the significant drawbacks of MySQL on Amazon RDS was limitation of […]

With Fabric's official GA release this week, I thought I would post a spin on how to setup a development environment loosely based on the Fabric Quick Start guide in the manual.

The notable change, is the use of MySQL Sandbox for bootstrapping each of the MySQL instances.

Step 1: Install the MySQL Utilities + Python Connector

In my case, I downloaded:

• mysql-utilities-1.4.3-osx10.7.dmg Mac OS X 10.7 (Architecture Independent), DMG Archive
• mysql-connector-python-1.2.2-osx10.7.dmg Mac OS X 10.7 (Architecture Independent), DMG Archive

The GUI install in both cases works as expected. Next, Next, …

MySQL has status variables “questions” and “queries” which are rather close but also a bit different, making it confusing for many people. The manual describing it might not be very easy to understand:

Queries
The number of statements executed by the server. This variable includes statements executed within stored programs, unlike the Questions variable. It does not count COM_PING or COM_STATISTICS commands.
 Questions
The number of statements executed by the server. This includes only statements sent to the server by clients and not statements executed within stored programs, unlike the Queries variable. This variable does not count COM_PING, COM_STATISTICS, COM_STMT_PREPARE, COM_STMT_CLOSE, or COM_STMT_RESET commands.

In a nutshell if you’re not using prepared statements the big difference between those is what …
