InfiniDB 1.5 Final is Now Available!

I am very excited to announce that the the FINAL 1.5 version of the InfiniDB Community Edition is now available for use.  Thanks to everyone in the community for helping us through the alpha, beta, and RC cycles to the 1.5 release of InfiniDB.

We've put a lot of hard work into this release and we've come a long way since 1.0. Here's a reminder of a few of the features that have been added since 1.0:

High-speed subqueries. 
Support for running on...

Doing your own on-time flight time analysis Part III

In the last post, the data from the on-time flight database was loaded in a column-orientated storage engine. Now the numbers can be crunched.

The original goal of this exercise was to find the flight from Los Angeles International Airport, LAX, to Dallas Fort Worth International Airport, DFW, that was the most likely to arrive on-time.

The data is 'opportunity rich' in that there is a lot information in there. It is easy to start wondering about the various nuggets of information in there. Are their certain aircraft (tail numbers) that are routinely bad performers? Are some days of the week better than others? Do national holidays have an effect on the on-time performance? If you are delayed, is there a 'regular amount' of delay? Does early departure make for an early arrival? Can the flight crew make up for a late departure? How much time is usually spend on runways?

But to look for the flight from LAX …

Anybody have a few millions lines of Apache Log files they can share?

Anybody have a few millions lines of Apache Log files they can share? I am working on a lab/demo on InfiniDB and need a few millions lines of an Apache HTTPD log file. I no longer run any large websites and would rather use real data over creating something. I will sanitize your URL so you will be anonymous, so will end up as or something similar.

The demo/lab will show how to load data into the columnar InfiniDB storage engine and run some analytics against the data. Please let me know if you can help.

InfinDB Extent Maps saving I/O

InfiniDB uses Extent Maps to retrieve data. Data is stored in extents and each extent is a logical block of space that holds the same number of rows.

The Extent Map catalogs all extents and their corresponding blocks. The Extent Map also maintains minimum and maximum values for a column’s data within an extent.

The Extent Map lets InfiniDB to retrieve only the blocks needed to satisfy a query. There is another benefit – that of logical range partitioning. This is accomplished via the minimum and maximum values for each extent that are contained within the Extent Map. Extent elimination is first accomplished in InfiniDB via the column-oriented architecture (only needed columns are scanned), but the process is accelerated because of the logical horizontal partitioning that is implemented in the Extent Map. So only the needed sections of the column are read. …

InfiniDB Alpha 1.1.2 on 64-bit Windows and MySQL Workbench

This week has been rough on my computers and I had to reinstall Vista on my main Windows system. But being a 'glass half full' guy, I took it as an opportunity to load the new alphas for both InfiniDB and MySQl Workbench.

I downloaded the InfiniDB software from and Workbench from respectively. In stalled them in that order and started the database and then Workbench.

I was expecting to have to fiddle with configuring one or the other to get them to work together. But I received a delightful surprise. Both worked out of the chute with no customization. Congratulations to the folks writing the install scripts at both companies!

Getting started with InfiniDB Part I

My new job with Calpont has me scrambling to learn all the facets of the InfiniDB storage engine. For those of you new to the scene, InfiniDB is column-orientated as opposed to row-orientated and is designed for data warehouses and business intelligence. Most MySQL DBAs are probably not used to thinking sideways and hopefully this series of postings will change that.

To make things interesting, I am using real data from BP's Statistical Review of World Energy 2009. The data is a historical information on various forms of energy. And it is free to download and comes in Excel workbook format. I wanted data that was unfamiliar to me and in a format that would be commonly used in a BI setting.

The first step is to obtain and install the …

No North Texas Users Group Meeting in May, new job

There will not be a May meeting of the North Texas MySQL Users Group but I am scrambling to get us a great location for the June meeting. I have left my Job with MySQL/Sun/Oracle and am no longer responsible for MySQL Certifications. That means my access to the Sun office were we have been meeting is ended also.

I am now the Customer Service Manager for Calpont and the InfiniDB storage engine. InfiniDB is column based, multi-threaded, and the community edition is open source. If you run intensive reports against InnoDB or MyIsam databases, you need to investigate this product. And if you regularly run massive queries in data warehousing or business analytic operation that you need to see how the massively parallel process architecture of the enterprise product can make life easier.

Log Buffer #182, a Carnival of the Vanities for DBAs

This is the 182nd edition of Log Buffer, the weekly review of database blogs. Make sure to read the whole edition so you do not miss where to submit your SQL limerick!

This week started out with me posting about International Women’s Day, and has me personally attending Confoo (Montreal) which is an excellent conference I hope to return to next year. I learned a lot from confoo, especially the blending nosql and sql session I attended.

This week was also the Hotsos Symposium. …

InfiniDB gets the release process right

InfiniDB has a sensible Enterprise/Community release process, which seems similar to what I suggested for MySQL. Its simplicity also stands in stark contrast to MySQL’s new release policy, which is hard to understand and has been confusing people.
