CQL is the SQL-like query language for Apache Cassandra.

Ideal for distributed, write-intensive, and scalable applications.

Supports keyspace/table creation, CRUD, TTL, and conditional updates.

Backed by a robust open-source community and enterprise support.

Is CQL still relevant?

Yes - essential for interacting with Apache Cassandra databases.

Is CQL beginner-friendly?

Moderately - SQL-like syntax but requires understanding partitioning.

Does Cassandra support ACID transactions?

Supports atomicity at row level; multi-row transactions via lightweight transactions.

Why choose Cassandra/CQL?

Highly scalable, fault-tolerant, and optimized for write-heavy workloads.
