We Recommend These Resources Within NoSQL, the operations of indexing, fetching and searching for information are intimately tied to the physical storage mechanisms. It is important to remember that rows are stored across hosts, but a single row is stored on a single host. (with replicas) Columns families are stored in sorted order, which makes querying a set of columns efficient (provided you are spanning rows).
Cassandra Indexing: The good, the bad and the ugly
Dominic Williams
My team is currently working on a brand new product – the forthcoming MMO www.FightMyMonster.com . This has given us the luxury of building against a NOSQL database, which means we can put the horrors of MySQL sharding and expensive scalability behind us. Recently a few people have been asking why we seem to have changed our preference from HBase to Cassandra. I can confirm the change is true and that we have in fact almost completed porting our code to Cassandra, and here I will seek to provide an explanation. For those that are new to NOSQL, in a following post I will write about why I think we will see a seismic shift from SQL to NOSQL over the coming years, which will be just as important as the move to cloud computing.Cassandra
Jumping from MySql to Cassandra, a success story… « IT Secrets
Today I’m gonna share with you my experience when I started with Apache Cassandra…One of the most complicated steps to learn any NoSql stuff, is to take away of your mind the normalization principles and those relational DB structures. Relational databases are designed to persist normalized data and without duplicated data. Well, one of the main changes here is that you need to think or design for your queries, in what your reports or finder methods want, and build a the persistent structure as it need.
