本文汇总了Cassandra的四种超时参数，包括服务端配置的超时参数（如read_request_timeout_in_ms, range_request_timeout_in_ms等），客户端读取数据的超时设定，特定请求的超时以及打通客户端与服务端的全链路超时设置，适用于优化Cassandra的性能和稳定性。" 128666095,8458078,MySQL索引原理与优化指南,"['数据库', 'MySQL', '索引']

1、服务端配置的超时参数（cassandra.yaml）：

*_request_timeout_in_ms族超时参数，在服务端配置，如read_request_timeout_in_ms、write_request_timeout_in_ms等

range_request_timeout_in_ms 
  (Default: 10000 milliseconds) The number of milliseconds that the coordinator waits for sequential or index scans to complete before timing it out.
read_request_timeout_in_ms 
  (Default: 5000 milliseconds) The number of milliseconds that the coordinator waits for read operations to complete before timing it out.
counter_write_request_timeout_in_ms 
  (Default: 5000 milliseconds) The number of milliseconds that the coordinator waits for counter writes to complete before timing it out.
cas_contention_timeout_in_ms 
  (Default: 1000 milliseconds) The number of milliseconds during which the coordinator continues to retry a CAS (compare and set) operation that contends with other proposals for the same row. If the coordinator cannot complete the operation within this timespan, it aborts the operation.
