Hey Vivek, The same thing happened to me the other day. You may be missing a component in your compound key.
See this thread: http://mail-archives.apache.org/mod_mbox/cassandra-dev/201210.mbox/%3ccajhhpg20rrcajqjdnf8sf7wnhblo6j+aofksgbxyxwcoocg...@mail.gmail.com%3E I also wrote a couple blogs on it: http://brianoneill.blogspot.com/2012/09/composite-keys-connecting-dots-between.html http://brianoneill.blogspot.com/2012/10/cql-astyanax-and-compoundcomposite-keys.html They've fixed this in the 1.2 beta, whereby it checks (at the thrift layer) to ensure you have the requisite number of components in the compound/composite key. -brian On Oct 8, 2012, at 10:32 PM, Vivek Mishra wrote: > Certainly.
