Tokens¶
The GRID_LRT.Token module is responsible for interactions with CouchDB using the PiCaS token framework. It contains a Token_Handler object which manages a single _design document on CouchDB, intended for a set of jobs that are logically linked together. In the LOFAR Surveys case, this holds the jobs of a single Observation. Additionally a Token_Set object can create batch tokens, upload attachments to them in bulk and change Token fields in bulk as well. This module is used in combination with the srmlist class to automatically create sets of jobs with N files each.
