Conquering Your Database Workloads
Howard Goldberg – Executive Director, Morgan Stanley, Head of Greenplum engineering
Everyone has been in some type of traffic delay, usually at the worst possible time. These traffic jams result from an unexpected accident, volume on the roadway, or lane closures forcing a merge from multiple lanes into a single lane. These congestion events lead to unpredictable travel times and frustrated motorists.
Databases also have traffic jams or periods when database activity outpaces the resources (CPU/Disk IO/Network) supporting it. These database logjams cause a cascade of events leading to poor response times and unhappy clients. To manage a database’s workload, Greenplum (4.3+) utilizes resource queues and the Greenplum Workload Manager (1.8+). Together these capabilities control the use of the critical database resources and allow databases to operate at maximum efficiency. This article will describe these workload manager capabilities and offer best practices where applicable. Read More
