  14. def mergeStreamingConfig(streamingConfig: Option[Streaming], outputOpts: Map[String, AnyRef]): Streaming

    Merge the streaming configuration with the output options for streaming queries.

    Merge the streaming configuration with the output options for streaming queries. This method is used to combine options from both streamingConfig and outputOptions. If the streamingConfig is None, it uses options from the outputOptions and applies default values as needed.

    streamingConfig

    Optional streaming configuration for the streaming query.

    outputOpts

    Output options for the writer.

    returns

    A Streaming object containing the merged streaming configuration.

    Validate if all mandatory arguments are present in the outputOptions map.

    Validate if all mandatory arguments are present in the outputOptions map. If any argument is missing, it throws a MissingWriterArgumentException.

    outputOptions

    The output options map containing the configuration for the writer.
