To use multiple output sinks with Spark structured streaming in Scala, you can follow these steps:
val inputStream = spark.readStream
.format("socket")
.option("host", "localhost")
.option("port", "9999")
.load()
val transformedStream = ...
val consoleSink = transformedStream.writeStream
.format("console")
.outputMode("append")
.start()
val fileSink = transformedStream.writeStream
.format("parquet")
.option("path", "/path/to/parquet/files")
.option("checkpointLocation", "/path/to/checkpoint")
.outputMode("append")
.start()
consoleSink.awaitTermination()
fileSink.awaitTermination()
Note that you can define as many output sinks as you need by repeating steps 3 and 4 with different output formats and options. Also, make sure to set different checkpoint locations for each sink to avoid conflicts.
