The CQL protocol is the client-facing path for submitting Cassandra Query Language queries to a Cassandra-compatible database. ScyllaDB preserves Cassandra compatibility while extending the protocol with shard awareness, allowing clients to route requests directly to the shard that owns them. section 8.2.3
Cql protocol
The CQL protocol is the client-facing protocol for submitting Cassandra Query Language operations to a Cassandra-compatible database.
How ScyllaDB in Action covers it
- How deep it goes
- Defines its purpose and shard-aware extension, but defers routing configuration details.
- Examples
- Uses client queries executed against the database as its practical example.
- What you can do after
- Apply it via CQL to submit queries and understand shard-aware client routing.
- How it connects
- Connects Cassandra compatibility with shard awareness and client-side request routing.
