Architecture
The IBM Db2 Analytics Accelerator utilizes a Hybrid Transactional/Analytical Processing (HTAP) architecture to process database queries.[1] The technology uses a columnar, compressed data format. While early versions were deployed as physical hardware appliances (using Netezza-based blades or IBM Power servers), newer versions support a "software-defined" deployment.[2]
In this modern model, the accelerator runs as a containerized service within a Secure Service Container (SSC) directly on IBM Z mainframes, utilizing Integrated Facility for Linux (IFL) processors. The solution is designed to allow analytical queries to run against near real-time transactional data without impacting the performance of the primary operational database.[3] The accelerator is frequently bundled with enterprise mainframe upgrades to improve analytical response times and reduce the total cost of ownership compared to distributed server environments.[4]
Data is stored on the accelerator in "shadow tables." The IBM Db2 for z/OS optimizer automatically determines whether to execute a query locally or offload it to the accelerator based on the estimated cost of the operation.[5]
History
The product was originally released in 2010 as the IBM Smart Analytics Optimizer (ISAO), a workload-optimized "add-on" designed to accelerate analytical queries on IBM Z by utilizing a memory-resident, columnar format.[6] Following IBM's acquisition of Netezza in late 2010, the technology was rebranded as the IBM Db2 Analytics Accelerator (IDAA) to reflect the integration of Netezza's massively parallel processing (MPP) architecture.[7]
