Why Is CPU Usage of a DCS Redis Instance 100%?

  • Possible cause 1:

    The service QPS is so high that the CPU usage spikes to 100%.

  • Possible cause 2:

    You have run commands that consume a lot of resources, such as KEYS. This will make CPU usage spike and can easily trigger a master/standby switchover.

  • Possible cause 3:

    Redis rewrite was triggered, increasing CPU usage.
