Feed Simulation Input Adapter Sample


This sample demonstrates the TIBCO StreamBase® Feed Simulation Input Adapter emitting data on two different streams. The two streams have identical schemas and both use data files as data sources. The data files contain fictitious market data captured from two different venues at the same time and for the same instruments. The two streams emit data based on an arrival timestamp and the two streams are time synchronized. In this way, the feed simulation emits data very close to the way two real market data handlers would emit actual market data.

The same feed simulation configuration file in this sample (sbfeedsim.sbfs) can be used by the sbfeedsim command line tool. Each of these approaches might be preferred under different circumstances.

Running This Sample in StreamBase Studio

  1. In the Package Explorer, double-click to open the sbfeedsim.sbapp module. Make sure the module is the currently active tab in the EventFlow Editor.

  2. Click the Run button. This opens the SB Test/Debug perspective and starts the application.

  3. The Feed Simulation adapter begins to emit data immediately. You can suspend, resume, and scale the tuple rate by sending commands to the input stream using the Manual Input tab in the SB Test/Debug perspective.

  4. When done, press F9 or click the Stop Running Application button.
