    sparkSession.config("spark.sql.streaming.schemaInference", true).getOrCreate();
    Dataset<Row> dataset = sparkSession.readStream().parquet("file:/files-to-process");

    StreamingQuery streamingQuery =
        dataset.writeStream().option("checkpointLocation", "file:/checkpoint-location")
            .outputMode(Append()).start("file:/save-parquet-files");
