Subject [jira] [Commented] (BLUR-174) Respect family order from given selector
Date Fri, 02 Aug 2013 08:33:52 GMT

    [ https://issues.apache.org/jira/browse/BLUR-174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13727484#comment-13727484
] 

Gagan Deep Juneja commented on BLUR-174:
----------------------------------------

If we can have only row_id as a term in query then this is fine. 
How can we fetch documents based on fieldName/fieldValue from indexSearcher. Because TopDocs
only provides the document Ids. So might be we need to have some other datastructure like
Map to maintain all the documents with their family name as key. 

May be I am asking this in bit detail because I think performance matters here.

Can we have Multiple records with same family name in a particular row?

Regards,
Gagan

> We need to respect the order of the families in the selector.  For instance if a table
contains 3 families, "cf1","cf2", and "cf3".  And a fetch (during a query or a fetch call)
is performed and the order of the families are "cf2", "cf1" then all the records from the
Row that contain "cf2" should come before "cf1".
> Changes needed:
> The families in the Selector object in thrift need to be changed from a set to a list.
> The fetchDocuments method in the BlurUtil class in blur-core needs to be modified to
respect the family order.
