PROCESSING STAGE

DECODE STAGE

The Decode stage is an active stage. It decodes a data set using a UNIX decoding command, such as gzip, that you supply. It converts a data stream of raw binary data into a data set. Its companion stage Encode converts a data set from a sequence of records to a stream of raw binary data. Follow this link for a list of steps you must take when deploying a Decode stage in your job.

As the input is always a single stream, you do not have to define meta data for the input link.

PROPERTIES

OPTION CATEGORY

Command Line. Specifies the command line used for decoding the data set. The command line must configure the UNIX command to accept input from standard input and write its results to standard output. The command must be located in the search path of your application and be accessible by every processing node on which the Decode stage executes.
