求助:Datastax Node.js Driver全量Cassandra异常码文档获取途径
Hey there! I’ve been in your shoes before when working with the DataStax Node.js Driver—tracking down that full list of ResponseError codes can be tricky when the official docs only call out a few. Here are the best ways to get the complete set:
Dig into the driver’s source code
This is the most direct and reliable method. Head to the driver’s source files (look for modules likeerrors.jsorresponse-error.jsin the package’s directory). You’ll find all the error code constants explicitly defined here, mapped to their numeric values and descriptive messages. For example, you’ll spot entries likeUNAVAILABLE,READ_TIMEOUT, andINVALID_QUERYwith their corresponding codes laid out clearly.Align with Apache Cassandra’s protocol error codes
The DataStax Driver’s error codes are directly based on Apache Cassandra’s native protocol specifications. All standard response error codes used by the driver mirror those defined in Cassandra’s core protocol. You can reference Cassandra’s official protocol documentation (focused on the version matching your driver/Cassandra cluster) to get a comprehensive breakdown of every code.Trigger errors intentionally in test code
If you want to see codes in action, create test scenarios that force specific errors: query a non-existent table, use an invalid consistency level, or simulate a timeout. Catch theResponseErrorin your code and log thecodeproperty alongside the error message. This hands-on approach lets you map real-world failure scenarios to their respective codes.Check the driver’s changelog and release notes
New error codes sometimes get added in driver updates. If you’re using a newer version, flip through the changelog or release notes—they’ll often call out any newly introduced codes that might not be fully documented yet.
