Select one of the following three modes in which the Snap executes:

  • Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.

  • Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.

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

Default Value: Execute only
Example: Validate & Execute

Snap type:

Format


Description:

This Snap formats the incoming document from the upstream Snaps to Hadoop sequence file format, the native binary data format to persist intermediate data between different stages of MapReduce jobs. 

Note
To enable Snappy compression for sequence file, a cluster level setting needs to be set. Unlike Parquet or ORC writer the Sequence Formatter Snap will not have "Snappy" listed in the "compression" options.
  • Expected upstream Snaps: The upstream Snap for Sequence Formatter should output map/table/key-value formatted data. Valid data types include String, Integer, Number and Boolean.
  • Expected downstream Snaps: The Sequence Formatter Snap outputs binary data, so the downstream Snap must be a data store output Snap like (File Writer, HDFS Writer, etc.).
