Apache Cassandra Query Language (CQL)
Apache Cassandra Query Language (CQL) is a SQL-like language designed for interacting with Apache Cassandra, a highly scalable, distributed NoSQL database. It provides a familiar, declarative interface for creating, reading, updating, and deleting data, abstracting away the complexities of…

- Problem solved
- CQL was created to significantly simplify the interaction with Apache Cassandra. Before CQL, developers had to communicate with Cassandra using its low-level Thrift API, which was verbose, required extensive boilerplate code for data serialization/deserialization, and lacked a declarative query interface. This led to a steep learning curve, increased development time, and made Cassandra less accessible to developers accustomed to SQL-based relational databases. CQL addressed this by providing a high-level, SQL-like syntax that made data manipulation intuitive and abstracted the complex internals of Cassandra's distributed, column-family data model.
