Complete Guide to Document Stores, Key-Value Stores & Database Selection
Understanding NoSQL Databases
Cassandra is a distributed column store designed for high availability
wide-column model with column families, providing efficient storage for sparse data. Cassandra excels at
write-heavy workloads, time-series data, and global distribution. It provides tunable consistency and
eventual consistency. NoSQL databases typically provide eventual consi
availability. Understanding consistency needs guides selection.
Strong consistency ensures all reads see latest writes but may impact performance. Eventual consistency

What is the rationale behind choosing NoSQL databases over traditional relational databases?
for flexible schemas, horizontal scalability, high-performance simple operations, or relationship-rich data.
When should a developer consider using NoSQL instead of a relational database?
NoSQL is suitable when relational databases don't meet requirements for scale, flexibility, or performance.
How does the selection process for a NoSQL database typically begin?
Selection depends on specific application needs.
What are the key distinctions between document and key-value stores?
