Run Task Request
In order to use custom T streams in Data Extracts, it necessary to specify the T_StreamName parameter in the Run Task Request (RTR) control message with a value of the name of custom T stream.
If the output format needs differ from the EagleML, that should be specified in the RTR too, using the OutputFormat parameter.
Let's consider the example of using custom T stream star_to_fixed_demo_t which has the output format FIXED. In the RTR, the output format should be defined as TagValue.
Example with star_to_fixed_demo_t T stream
