Try making user_name a primary key in combination with some other unique column and see if results are improving. -Rishabh From: Vivek Mishra [mailto:mishra.v...@gmail.com] Sent: Friday, October 05, 2012 2:35 PM To: user@cassandra.apache.org 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? -Vivek ________________________________ Impetus Ranked in the Top 50 India's Best Companies to Work For 2012.
