Subject Cannot query secondary index
Date Mon, 09 Jun 2014 21:18:02 GMT
I have a table with a timestamp column on it; however, when I try to query
based on it, it fails saying that I must use ALLOW FILTERING--which to me,
means its not using the secondary index.  Table definition is (snipping out
irrelevant parts)...

>     date timestamp,

>     PRIMARY KEY (id, date)

> CREATE INDEX date_idx ON audit (date);

There are other fields, but they are not relevant to this example.  The
date is part of the primary key, and I have a secondary index on it.  When
I run a SELECT against it, I get an error:

cqlsh> SELECT * FROM asinauditing.asinaudit WHERE date < '2014-05-01';

How can I force it to use the index?  I've seen rebuild_index tasks
running, but can I verify the "health" of the index?
