Parquet Writer


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.

Input Ports

  1. Type: Remote Connection An optional connection to the remote file system
  2. Type: Data The data table that should be written
