NodeParquet Writer

Sink

This node writes the KNIME data table into a Parquet file. The Parquet file can be written locally or on a remote file system.

For remote connections, the writer stores chunks locally and uploads them in parallel into a folder with the given name. The chunks size and the number of chunks that are allowed on local disc, are configurable in the "Chunk Upload" tab which is only enabled for remote file systems.
