Partitioned Tables: Significant Enhancements in DB2 9.7 (and beyond) (C16)

Topic: 2010 EMEA

Subtopic: DB2 for LUW

DATE: 2010-11-11 (09:45 - 10:45)
SPEAKERS: Mike Winer (IBM)

This session will cover the significant enhancements to Partitioned Tables in DB2 for LUW since they were first introduced in DB2 9.1. To begin with, an overview of the partitioned table architecture, example use cases, ease of use using DDL, and best practices will be presented.New to DB2 9.7, partitioned indexes are now supported, allowing each data partition to be indexed separately compared to the non-partitioned indexes available in prior versions. This session will cover partitioned indexes and how they can improve and increase usability, scalability, performance, etc.In DB2 9.7 FP1, performance and availability on partitioned tables are improved. DETACH of a data partition no longer requires all current access to the table to drain, allowing long running queries to continue without impeding the DETACH operation. In addition, DB2 9.7 FP1 will also allow users to issue REORG operations on a single data partition vs. the entire partitioned table, allowing for faster REORG operations, increasing the availability to other data partitions of the partitioned table.We will share some ideas on a few additional enhancements that are on our white-boards, no commitments of course! The audience will have their own ideas of other things they might like to see from DB2 for partitioned tables. Time permitting, an open discussion will be held.
