Subject Re: cql/secondary indexes - select in
Date Tue, 14 Jun 2011 13:33:50 GMT
We gave this a try in -- it turns out
it's not a good fit for the CQL QueryProcessor. We really need to be
able to push more complex queries to the index nodes

So, we would still like to do this eventually but probably not soon
because of the difficulty involved.
