什么是端口 9042?
Port 9042 is the native CQL (Cassandra Query Language) port for Apache Cassandra, used by all modern Cassandra drivers and client applications. The CQL binary protocol replaced the legacy Thrift protocol and provides a more efficient and feature-rich interface for database operations. This is the primary port that applications use to communicate with Cassandra clusters.
