本文记录了作者在使用Cassandra集群过程中遇到的三次ReadTimeout错误及一次成功查询的经历，并表达了对于集群优化的需求。

前后四次查询，前三次查询错误分别如下，只有第四次查询出来数据

ReadTimeout: Error from server: code=1200 [Coordinator node timed out waiting for replica nodes' responses] message="Operation timed out - received only 0 responses." info={'received_responses': 0, 'required_responses': 1, 'consistency': 'ONE'}

ReadTimeout: Error from server: code=1200 [Coordinator node timed out waiting for replica nodes' responses] message="Operation timed out - received only 0 responses." info={'received_responses': 0, 'required_responses': 1, 'consistency': 'ONE'}

OperationTimedOut: errors={'172.20.5.2': 'Client request timeout. See Session.execute[_async](timeout)'}, last_host=172.20.5.2

怎么优化集群，蛋疼，英文看着真费劲
