Orchestrating an analytic workflow in the Teradata Unified Data Architecture

Overview

This article describes how to combine exploratory analytics and operational analytics within the Teradata Unified Data architecture (UDA). The UDA is a logical and physical architecture that adds a data lake platform to complement the Teradata Integrated Data Warehouse. In the Teradata advocated solution, the data lake platform can either be Hadoop or a Teradata Integrated Big Data Platform optimized for storage and processing of big data. Query Grid is an orchestration mechanism that supports seamless integration of multiple types of purpose built analytic engines within the UDA.

Routing Options in Unity Director 15.00

Unity Director has a wide set of capabilities to control where users and requests are routed. Unity Director 15.00 now offers so many choices and ways to control things; they can be a little confusing. Let's talk about some of the most common uses for the available routing options (and some cool ones you might not have considered yet).

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

What's New in 15.10 for Unity Ecosystem Manager

Unity Ecosystem Manager 15.10 release is now GCA.  Ecosystem Manager is tightly integrated with Unity Director/Loader, Data Mover, Load utilities and BAR to achieve high availability and disaster prevention/recovery.  It is an integral part of the Unity Portfolio (Unity Director/Loader and Unity Data Mover) providing a holistic view of the entire Unified Data Architecture (UDA).  Ecosystem Manager can be deployed in single and multi-system UDA environment.

 

Unity Data Mover 15.10 Release

We are pleased to announce the General Customer Availability (GCA) of Unity Data Mover 15.10 as of June 2015. With release 15.10, Unity Data Mover is now certified with Teradata Database 15.10. Data Mover 15.10 can utilize QueryGrid/foreign server connections to move data from Hadoop to Teradata (if installed) in addition to using the Teradata Connector for Hadoop (TDCH).  Hadoop support has also been extended to support TDH 2.1.7, Hortonworks 2.1.7 on commodity hardware and Cloudera 4.3 on commodity hardware. Aster support is extended to Aster 6.10.

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.

Hadoop support has also been extended to support TDH 2.1 and 1.3.2.

What's New in 15.00 for Unity Ecosystem Manager

Unity Ecosystem Manager is part of the Teradata Unity portfolio of products supporting multi-system Teradata Environments.  While part of the Unity portfolio, it can also be leveraged as an event-driven system for efficient monitoring, alerting  and control of an entire analytic environment (Applications, Servers, Jobs, Tables) for a single Teradata, Aster or Hadoop system. 

What's New in 14.10 for Unity Ecosystem Manager

Unity Ecosystem Manager (Ecosystem Manager) is part of the Teradata Unity portfolio of products (Unity Director, Unity Loader, Unity Data Mover and Unity Ecosystem Manager).  Ecosystem Manager monitors and controls critical applications in both single and multi-system Teradata environments.  It is an event-driven system that monitors operations, generates alerts, and pushes those mission-critical application alerts to operations staff, DBAs, and other subscribed EDW staff.
