Snap type:

Format


Description:

This Snap formats the incoming document from the upstream Snaps to the RC (Row columnar) file format used for storing data in an optimized way to answer aggregate queries faster.

  • Expected upstream Snaps: The upstream Snap should output table oriented data with columns and rows.
  • Expected downstream Snaps: The RC File Formatter Snap outputs binary data, so the downstream Snap must be a data output Snap (i.e. File Writer, HDFS Writer, etc.).
