One of the keys to Aster’s parallel processing power are Virtual Workers (or v-workers).  V-Workers are the compute and storage units in an Aster cluster, much like AMPS are for Teradata.  In this article, I’ll show you how to easily add another v-worker in a procedure called ‘partition splitting’.  This will double the “parallel computing” of our Aster Express cluster.

Eliminating Unplanned Delays Within Load Utility Jobs

If you are using utility throttles in Teradata 13.10 to manage concurrency of your load jobs, any delay action against the utility job's unit of work will happen cleanly at the beginning of the load job.  However, there may be times where the load activity can be unexpectedly held up after the utility has begun execution.  This posting describes the particular conditions under which this may happen, and points to a simple adjustment you can make to keep it from happening again.

Data temperature, a metaphor for frequency of access, is used by Teradata Virtual Storage (TVS) to automatically move data throughout the spectrum of storage media (e.g. from HDD to SSD) based on performance needs. Teradata believes that every organization possesses a wide range of value in the data they use for analytics. Consequently, we are pursuing a strategy to match the cost of storage to the value of data in the organization – using all classes of storage simultaneously (in-memory, SSD, performance disk, capacity disk, and archives).

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.
