I had the pleasure of being invited to blog at the MassTLC unConference on Friday. The event was a full day of diverse topics and discussions ranging from the latest in recipe sharing sites, to entrepreneurial CEO war stories, to hot trends in venture investing. An excerpt covering Big Data from my MassTLC blog is below.

Big Data and Analytics in MA

Hosted by Steve O’Leary of Aeris Partners and Bob Zurek (@bzurek) of Oracle

First question – what is Big Data? While often debated, Steve had a working definition of “big” in terms of Volume, Velocity and Variety. Fritz Knabe of IBM noted that Big Data can come from even the most unexpected places, such as the point-of-sale coupons at checkouts as managed by Catalina (an IBM customer). …

After more than 6 years doing MySQL Support for MySQL AB, Sun Microsystems, and Oracle, it’s time for a change. Time to get back to development!

As of November 2011 I’ll be working full-time on MySQL Connector/Python and other goodies within the MySQL development team at Oracle. Before, this was more or less a pet project done after working hours. However, with the birth of our son Tomas more than a year ago, I’ve been slacking and family got priority.

The idea is to make MySQL Connector/Python the best choice for connecting to MySQL from within your Python code. We still got …

Last week was a bumper week in London for MySQL users, DBAs & developers. We had the Oracle MySQL Developer Day and Percona Live London 2011. Both events were sold out, bringing in a good 300+ people to each event. From what I could tell the crowds were quite unique, so thats a good 600+ people interested in MySQL in London. The death and unpopularity of MySQL is greatly exaggerated.

At Oracle’s event, we naturally only had Oracle presenters. There was Simon Deighton (Sales Manager), Tony Holmes (Sales Consultant), …

From Percona Live, London to TechEd Australia to Oracle Open World USA, the blogosphere of Oracle, MySQL, SQL Server and the related technologies is bustling with the eye witness accounts of these conferences, technical overviews, observations, predictions, and much more. This Log Buffer Edition covers all that and as usual more in Log Buffer #243. [...]

Many database management tasks become difficult as you move from millions of rows and gigabytes of data to billions of rows and terabytes of data. Such tasks include ingesting data while maintaining indexes; changing schemas without downtime; and supporting connections, replication, and backup. For some scaling problems (connections and replication), MySQL® is better than most of the competition. For others, such as indexing, schema changes, and backup, MySQL has typically been harder to use. Fortunately, the tasks MySQL does well are in its core, whereas the tasks that are more difficult can be solved with storage engine plug-ins.

I recently gave a talk at Oracle Open World 11, a copy of which can be found here. This presentation discusses how MySQL’s storage engines have recently made dramatic progress in large database manageability.

A list of …

Whenever Oracle Open World ends, it not only leaves the technology professionals in awe and full of pride, it also makes them come up with new and great blogging ideras and this Log Buffer Edition covers that flowing notions from bloggers across the Oracle and MySQL beauties, in addition to SQL Server in Log Buffer [...]

As I'm mostly using Oracle for work projects, the concept of the DUAL dummy table has become quite intuitive. I hardly ever think about the days when I was playing around with that table to find out its purpose (e.g. writing into it when DUAL was still a physical object, and thus killing the whole … Continue reading SQL Trouble with dummy tables →

Starting with MySQL 5.5.16 it is possible to setup a password-less connections from clients into MySQL server using Windows SSPI authentication framework. This functionality is provided by Windows Native Authentication (WNA) plugin distributed with the commercial version of 5.5.16 server. The client-side support for WNA authentication is built into the client library (libmysql) distributed with the community version of 5.5.16 server and requires no additional configuration. Clients which link to 5.5.16 or higher version of libmysql will be able to connect to MySQL accounts using WNA authentication out-of-the box.

For password-less connections to work, server's administrator must install the WNA plugin in the server and create user accounts which use this plugin for authentication. It is also possible to allow connections to existing MySQL accounts via a proxy WNA account. With this setup Windows clients can password-less connect to the …
