Scaling Out Query Performance with Sybase® IQ 15.3
Using the PlexQ™ Distributed Query Platform, a Shared Everything MPP Architecture
Sybase IQ 15.3 introduces the PlexQ™ Distributed Query Platform, a Massively Parallel Processing (MPP) architecture that accelerates highly complex queries by distributing work to many computers in a Multiplex configuration. Unlike shared-nothing MPP architectures, PlexQ utilizes a shared-everything approach that dynamically manages and balances query workloads across all the compute nodes in a Sybase IQ MPP configuration. PlexQ’s automatic workload re-balancer aggressively works to avoid contention among users for system resources, thereby providing predictable high performance and resource efficiency for a broad spectrum of concurrent workloads.
