Thanks for the response. Further questions inline.. On Mon, Jul 9, 2012 at 11:50 AM, samal <samalgo...@gmail.com> wrote: >> 1. With RandomPartitioner, on a given node, are the keys sorted by >> their hash_values or original/unhashed keys ? > > hash value,
1. Based on the second answer in http://stackoverflow.com/questions/2359175/cassandra-file-structure-how-are-the-files-used it seems that the index-file ( for a given ssTable ) contains the row-key ( and not the hash_keys ). Or may be I am missing something. 2. Do the "keys" in Index-file ( ref http://hi.csdn.net/attachment/201111/28/0_1322461982l3D8.gif ) actually contain : hash(row_key)+row_key or something like that ? Otherwise you need a separate mapping info from hash_bucket -> rows for reading. -Thanks, Prasenjit
