Try making user_name a primary key in combination with some other unique column and see if
results are improving.

Subject: Query over secondary indexes

I have a column family "User" which is having a indexed column "user_name". My schema is having
around 0.1 million records only and user_name is duplicated  across all rows.

Now when i am trying to retrieve it as:

get User where user_name = 'Vivek', it is taking ages to retrieve that data. Is there anything
i am doing wrong?

Also, i tried get_indexed_slices via Thrift API by setting  IndexClause.setCount(1), still
 no luck, it got hang and not even returning a single result. I believe 0.1 million is not
a huge amount of data.

Cassandra version : 1.1.2

Any idea?
