Subject [jira] Commented: (CASSANDRA-749) Secondary indices for column families
Date Wed, 26 May 2010 03:44:36 GMT


Vijay commented on CASSANDRA-749:

I was watching this ticket... and i think we can do one more thing to make the local-index
more efficient (If the user gives hits)... For example: while writing data the user can say
(hint, key) --> which will be used by the partitioner to keep the data closer within a
range of nodes.... scaling will not be a problem, when user adds nodes it will go to the most
populated node anyways.... While querying if the user gives us the hint like (Org, valueToSearch)
then we know where to search for. Just an interm solution to scale queries?
