Snap type:

Transform


Description:

This Snap decompresses the contents of a binary stream. For example, if a File Reader Snap was configured to read a compressed file, you can use this Snap to decompress the contents before passing the data to a parsing 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 of the binary stream. 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

The Decompress 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.
