With relational data modeling, you can start with the primary key, but effective data models in an RDBMS are much more about the foreign key relationships and relational constraints betwRead More..
In this blog post, we’ll explain the reason why all Cassandra experts and evangelists promote single-partition operations. We’ll see in details all the benefits that single-partition operations can provide in term of operation, consistency and system stability.
Atomicity & Isolation
Mutations (INSERT/UPDATE/DELETE) to all columns of a partition are guaranteed to be atomic e.g. the upd Read More..
