gocql: no response received from cassandra within timeout perio

I also have three Cassandra servers as a cluster. Sometimes, there may be timeout errors during write operations (writing simple string data), but the write has already been successful. At this time, reading again will also report a timeout, which is difficult to reproduce. The only thing I can know is that the read and write timeout is 2 seconds, which is very long for my program

No source file, test, or entry point is identified. Start by reproducing the behavior with a three-server Cassandra cluster, simple string writes and reads, and two-second timeouts; inspect driver and Cassandra logs to determine whether the timeout follows a successful write. Done means the cause is identified and the behavior is covered by a reliable regression test.
