You can use this Snap to decompress the contents content of a binary streamdata. For example, if a File Reader Snap is configured to read a compressed file, you can use this Snap to decompress the contents content before passing the data to a parser Parser Snap. It currently supports decompressing files in the GZIP, BZIP2, and DEFLATE compression schemes. The decompression scheme can be explicitly chosen or automatically detected based on the contents content of the binary streamdata. If the compression scheme is set to AUTO and the incoming data is not compressed, the raw input data is passed through without any changes.

Note

This Snap only uncompresses the compressed files on the first level. It does not decompress the archived folders which are located at the second level and deeper. This Snap supports decompression of the following compression schemes:

  • GZIP

  • BZIP2 (or BZ2)

  • DEFLATE

  • ZIP

  • 7ZIP

Field Name

Field Type

Description

Label*

Default Value: Decompress
Example: Decompress

String

Specify the name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your Pipeline.

Scheme*

Default Value: AUTO
Example: BZIP2


Dropdown list

Specify the decompression scheme to use. The available options include:

  • Auto - Automatically detects the decompression scheme to be applied (based on the compression scheme) on the incoming documents. This scheme supports ZIP and 7z.

  • Bzip2 - Decompresses files compressed in the BZIP2 compression scheme.

  • Gzip - Decompresses files compressed in the GZIP compression scheme.

  • Deflate - Decompresses files compressed in the DEFLATE compression scheme.

  • ZIP - Decompresses files compressed in the ZIP compression scheme.

  • 7z - Decompresses files compressed in 7z compression scheme.

Note

AUTO Scheme - Supported schemes

Automatic scheme detection and decompression is possible only for the three supported compression schemes - GZIP, BZIP2, and DEFLATE. 

Snap Execution*

Default Value: Validate & Execute
Example: Execute only

Dropdown list

Select one of the three modes in which the Snap executes. Available options are:

  • 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.
