Subject [jira] [Commented] (BLUR-174) Respect family order from given selector
Date Thu, 01 Aug 2013 00:23:48 GMT

    [ https://issues.apache.org/jira/browse/BLUR-174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13725895#comment-13725895
] 

Aaron McCurry commented on BLUR-174:
------------------------------------

We don't need to order the documents in search only within a single Row when the row is being
fetched.  If you take a look at the BlurUtil.fetchDocuments class you will see where we select
the documents based on families, this is where we need to enforce the Document/Record order.

There can only be a single family field on a document.  In other words, a Record has a single
family and a Record == Document.

Let me know if you have anymore questions.

Thanks!

Aaron

> 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.
