Why Is Memory Usage of a DCS Instance 100%?

  • Possible cause 1: The expiration time is not set for the instance. As a result, a large amount of data is stored.

    In this case, log in to the DCS console to perform big key analysis on the Cache Analysis page and query slow logs on the Slow Log page. If the expiration time is not set for the instance, data stored in the instance will use up the memory.

  • Possible cause 2: Due to the lazy free feature of Redis, expired keys may stay in the memory.
