Key Features

A key design goal was to build a very rich functionality superset into the feed handlers themselves. Although the broader Wombat architecture has components supporting value added servers, re-publishers, internal publishers, etc, the underlying feed handler design is intended to roll as many critical functionality sets as possible into a single process (often execution thread).

These include:

• Connectivity management
• Data parsing and normalization
• Symbology mapping
• Value added data
• Full order books
• Corporate actions
• Caching
• Subscription management
• Fault tolerance
• Initial values
• Snapshot and streaming data

This approach has effectively compressed a broad cross-section of market data system functionality into a single architectural level.

A more detailed discussion of the Wombat feed handler architecture is available in the "Wombat Universal Feed Handler Suite" white paper downloadable from Technical / Whitepapers.
