## What it is
A modern, feature-rich Java client library for Apache Cassandra 2.1+, DataStax Enterprise, and DataStax Astra, communicating via Cassandra's binary protocol and CQL v3. It is published as modular Maven artifacts including a core driver, query builder, and object mapper.

## Use cases
- connect to Apache Cassandra from a Java application
- run CQL queries against a Cassandra cluster
- map Java objects to Cassandra tables
- build CQL statements programmatically
- connect to DataStax Astra from JVM code
- tune connection pooling and load balancing for Cassandra

## When to choose
- you need a JVM client for Cassandra 2.1+ or DataStax Astra
- you want a highly tunable, feature-rich driver with query builder and mapper modules
- you are building Java 8+ applications against Cassandra's native binary protocol

## When to avoid
- you use a non-JVM language (use that language's Cassandra driver instead)
- you need a REST/HTTP interface rather than a native protocol client
- you require binary compatibility with the legacy 2.x/3.x driver API

## Facets
- artifact type: library
- maturity: active
- function: database-driver, serialization
- domain: databases, developer-tools, backend
- platform: jvm, cross-platform
- tags: cassandra, cql, nosql, datastax-astra, query-builder, object-mapper
