pyspark.sql.DataFrame.isStreaming¶

property DataFrame.isStreaming¶

Returns True if this DataFrame contains one or more sources that continuously return data as it arrives. A DataFrame that reads data from a streaming source must be executed as a StreamingQuery using the start() method in DataStreamWriter. Methods that return a single answer, (e.g., count() or collect()) will throw an AnalysisException when there is a streaming source present.

New in version 2.0.0.
