The UDA channel is a place for information sharing regarding Teradata’s Unified Data Architecture including the Analytical Ecosystem and other UDA influences.  This channel provides information specific to the integration and co-existence of multiple systems, in particular when a mix of Aster, Teradata, and Hadoop are present. It is also meant to support information around the UDA enabling technologies so products like Viewpoint, Data Mover, Connectors, QueryGrid, etc.

Performance analysis of Query Grid queries using Teradata DBQL

Introduction

The following article describes how to use Teradata DBQL tables to analyze the performance of Teradata to Hadoop (T2H) queries that transfer data from Hadoop to Teradata. This articles focuses on the steps that are part of the interaction between Teradata and Hadoop, it should be clear that query can have multiple other pre and post processing Teradata steps.

T2H has two processing methods

Doing the join-index shuffle with Unity Director/Loader

Life often requires comprises. In a data warehouse, there's often a trade-off between providing quick response times to reporting users running complex reports, and loading tables with new up-to-date data. Adding join-indexes to a table can speed up reports, and solve redistribution problems, but do come at a cost to table updates.

Working with Identity Columns and Unity Director and Loader

One of Unity Director and Loader’s core benefits is the ability to keep multiple Teradata systems synchronized with online, transactional-consistent, changes. Unlike post-transactional replication, Unity Director’s SQL-multicast sends requests in parallel to all connected systems at the same time. It also performs consistent checking on the responses of every write statement to ensure changes both systems succeed and produce the same results.
