Input Adapter Map File

The map file configures the interface between the Reuters Marketfeed adapter and Event Stream Processor. It specifies which source streams receive data from RMDS via the adapter, and it maps specific RMDS Field Identifiers (FIDs) to specific columns in that source stream.

The input adapter map file must accomplish three major tasks:

Match incoming data elements to columns in one or more streams defined in the Event Stream Processor configuration file.
Match the RIC provided with each update from the adapter with a row in the Event Stream Processor configuration file.
Ensure that each update from the adapter can be converted into a record that provides a unique key for each stream being populated, as defined by the stream's column definitions.
