The Rai Cache is a high performance last value cache and market data services provider with support for an extensible set of transports and message formats.
The Rai Cache architecture allows for the mixing and matching of components to achieve various functions. The set of components within each type is extensible:
- Protocol Emulators are modules which fully implement the service side protocol for an existed market data system. The Rai Cache can then act as a drop in replacement for such systems. Emulators are service providers of such systems.
- Protocol Bridges allow the Cache to pull data from and feed data to an existing market data system. Bridges are service consumers to such systems.
- Rai Services are modules that extend the feature set of the core Cache – examples include a backing store, delay service, or a statistics gathering mechanism.
- Embedded modules are written using the Rai API and loaded statically or dynamically into the Cache to provide specific functionality. Embedded modules provide a clean interface between Cache services. For example, data provider specific field transformations are typically implemented as an embedded module. Embedded modules can be written and maintained by our clients and loaded dynamically at runtime if desired.
