Session title: Why is Db2 Warehouse faster with Native Cloud Object Storage?
Session abstract: Cloud Object Storage (COS) was introduced as a new persistent storage medium for Db2 Warehouse in 11.5.9, and it brought new challenges due to significant I/O performance differences between traditional block storage and COS.
In this presentation we will discuss the new multi-tier architecture that was introduced for Native COS support, and the performance optimizations that were implemented in order to make it faster than block storage. We will also show various internal performance results that we used to optimize Native COS tables out of the box, and best practices to get the best insert and query performance.
