如何使用node.js关闭与cassandra的连接

Question

How to close connection with Cassandra in node.js? If I didn't close the connection, I will encounter an error. The error is Error:

All host(s) tried for query failed. First host tried, 10.XXXXX:OOO: Error: connect EMFILE

I have seen the solution in datastax. It suggest that it could be solved by the command: process.exit() . But it will kill the whole node.js process. That is not what I want. I just want to close the cassandra connection not the whole node.js process. Is there anyone has good solution to this?

Answer 1

You should call shutdown() before exiting:

client.shutdown();

You can provide an optional callback.

You should only call client.shutdown() once in your application's lifetime .
