Subject [jira] [Commented] (FALCON-265) reverse lookup for falcon entity definition
Date Sun, 28 Sep 2014 05:10:34 GMT

    [ https://issues.apache.org/jira/browse/FALCON-265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14150972#comment-14150972

Ajay Yadav commented on FALCON-265:
-----------------------------------

I am considering to choose between one of the following options for CLI command and REST API
URL.

# *falcon entity -type feed -lookup /projects/data/2014/09/10* and API URL on lines of *api/entities/:entity-type?path=/projects/data/2014/09/10*

# *falcon feed -lookup /projects/data/2014/09/10* and API URL on lines of *api/feed?path=/projects/data/2014/09/10*

IMHO, basic difference between the two is the entity type option and since this option is
of no use on entities other than feed, the second option being more concise should be used.

Thoughts?

> Can we have an option to reverse lookup an entityspecification?
> For instance, 
> 1. Given a path find the corresponding feed definition.
> 2. Given an input feed name, list the corresponding processes.
> Note that [2] is not the same as -dependency option, since depedency option list all
dependencies, including both input and output.
