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.).


Prerequisites:

[None]


Support and limitations:Works in Ultra Task Pipelines.
Account: 

Accounts are not used with this Snap. 


Views:


InputThis Snap has at most one document input view.
OutputThis Snap has at most one document output view.

  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Default Value: Execute only
