Summary

Configuration used to define a stream source using a Data Source Function.
 
The SparkStreamConfig class is used to configure a stream source using a user defined Data Source Function.
 
This class is used as an input to a StreamSource's parameter stream_config. Declaring this configuration class alone will not register a Data Source. Instead, declare as a part of StreamSource that takes this configuration class instance as a parameter.
 
Do not instantiate this class directly. Use :tecton.spark_stream_config instead.
