tecton.SparkStreamConfig

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.

danger

Do not instantiate this class directly. Use tecton.spark_stream_config() instead.

Parameters

• data_source_function (Callable[[SparkSession], DataFrame]) – User-defined Data Source Function that takes in a SparkSession and returns a streaming DataFrame.
