Writing file to S3 bucket

Currently when I write a file into S3 bucket, it gives output files in partitions. How do I write a file to S3 bucket in a single CSV file, rather than the files being divided into multiple parts? A single file which contains the contents from all the partitions.

Hello @tjmbakwe,

and welcome to KNIME Community!

What nodes do you use and how does you workflow design looks like?


if you are using the Spark to CSV node you can override the Spark DataFrame partition using the Overwrite partitions count option which results in a single csv file. By default Spark is simply writing out as many files as the DataFrame has partitions.
