My use case is as follows: we are using in 70% of the jobs information retrieval using keys, column names and ranges and up to now, what we have tested suits our need. However, the rest of 30% of the jobs involve full sequential scan of all records in the database.
I found some web pages describing the next good thing for cassandra 0.8 release, CQL, and I'm wondering: the CQL execution will involve separate processes running simultaneously on all nodes in the cluster that will do the "filtering and pre-sorting phase" on the local stored data (using indexes when available) and then execute the "merge phase" on a single node (that one that have received the request) ? Best regards, Teo
