Flow Control and Spawned Work

There’s a comment on an earlier blog posting of mine from 2009 titled Controlling the Flow of Work in Teradata.  The comment poses a question that is more reasonably answered by making second posting on flow control.

Teradata Mainframe Client Utilities update

Teradata has completed a major compiler conversion effort that should be completely transparent to customers, yet they are the main beneficiaries.  This article:

lasca.js, Custom Unicode Sorting for Internationalized Web Applications

A common problem with web applications is that sorting results are inconsistent between the front-end and back-end because the browser and server collation tables differ. These differences force a developer to do all sorting either in the front-end or back-end, which is not very good solution. An application should not have to pay a penalty of a network call just to sort and the server should not get pinged for every sort either. A developer should have the ability to select the best solution for a given problem.

The foundations of the Aster platform are a parallel database with all the features you'd expect from a SQL platform.  However the power of the Aster platform really shines once you start using its library of SQL-MR analytic components.  With these components, complex data analysis that is difficult to code in SQL becomes much, much easier.  A clear example of this can be seen with Aster's nPath module.
