Subject [jira] [Commented] (FALCON-1490) Support OR in filterBy
Date Wed, 07 Oct 2015 11:17:27 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14946690#comment-14946690

Narayan Periwal commented on FALCON-1490:
-----------------------------------------

As [~pallavi.rao] mentioned, right now, it is AND across filter fields and OR within a single
field. I went through all the filterBy use-cases and found some following inconsistencies
:
1. For entity list and summary, the OR is inconsistent within the field CLUSTER and PIPELINES.
Only the first value of these field is being considered for filterBy rather than considering
the OR.
for example, falcon entity -type process -list -filterBy PIPELINES:lda,PIPELINES:cob
This will output the process with pipeline=lda. "PIPELINES:cob" is ignored.

I am not sure if this behavior is because of any particular use-case. If there is any such
historical reason, kindly let me know, otherwise I will go ahead with making this behaviour
consistent.

> As of now only AND is supported in filterBy, it would be useful to have OR support too
so that users can use filterBy accordingly.
