Using InfiniDB MySQL server with Hadoop cluster for data analytics
+1 Vote Up -0Vote Down

In my previous post about Hadoop and Impala I benchmarked performance of analytical queries in Impala.

This time I’ve tried InfiniDB for Hadoop (open-source version) on the modern hardware with an 8-node Hadoop cluster. One of the main advantages (at least for me) of InifiniDB for Hadoop is that it stores the data inside the Hadoop cluster but uses the MySQL server to execute …

Doing your own on-time flight time analysis Part III
Employee +2 Vote Up -0Vote Down

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 …

Anybody have a few millions lines of Apache Log files they can share?
Employee +0 Vote Up -0Vote Down

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 www.YourCompanyHere.com will end up as www.abc123.com 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.

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 …
