Often an ECL query will consist of a series of results or actions which should all be executed together. Historically there have been two ways of grouping actions together.

P := PARALLEL(a1, a2, a3, a4);

PARALLEL indicates that all of the actions can be executed in parallel. If any intermediate values are common to more than one of the actions, then the values should only be evaluated once, and the result reused by each action.

This blog is going to be a bit of an eclectic mix. It will cover the background behind some of the features being added to the platform, what to watch out for when using ECL, and maybe a bit more detail about what goes on under the covers.

The first topic I want to look at is the way fields are optimized, and the motivation behind a new optimization in 4.2….

Last week, close to 300 people met in Delray Beach, Florida, to follow an intensive and densely packed agenda full of technology content on the HPCC Systems platform. It was our third annual HPCC Summit event and doubled its attendance from the previous year.

For those who don't know me, here is a brief intro in the context of this blog post.

Some people say I talk a lot!? Just so you know, I am not all talk. I explore, I hack and I get it done; more often than not, I am on my own end to end on the getting it done side of things.

As the end of the 2012 calendar year approaches, at least for a good chunk of the world (and may come to an end on 12/21 for a crazy bunch), some people start celebrating holidays in different cultures and countries. I consider this season a good time to go over things to come in the HPCC Systems platform arena.

I often get asked about comparing the HPCC Systems platform and Hadoop. As many of you probably know already, there are a number of substantial differences between them, and several of these differences are described here.
