Whitepaper: Scaling Out Query Performance with SAP IQ PlexQ

SAP IQ has a Massively Parallel Processing (MPP) architecture called PlexQ™ that accelerates highly complex queries by distributing work to many computers in a grid. 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 Multiplex grid. 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.
