Performing the majority of the data processing at the datasource level makes it possible to achieve increased event throughput and decreased event latency. The Integration Adapter Framework (IAF) transport/codec handles complex processing. This allows for more efficient processing and also facilitates the transmission of data in deltas instead of using full data snapshots. In addition to increasing efficiency, this design eliminates datasource-specific service monitors in most cases.  

The MDA libraries support the IAF with performance enhancements and filterability; they do not replace it. All common functionality for processing market data from sessions is included in a generic data source library, which can be used by all datasources. The following illustration depicts the MDA relationship to the IAF framework.
