ApsaraDB for Redis allows you to modify specific instance parameters. The instance parameters that can be modified vary based on engine versions and architectures. This topic describes how to modify instance parameters.


Some parameters are not supported in earlier instance minor versions. If your instance is in an earlier minor version, the following error message may appear when you set the parameters. You must update your instance to the latest minor version. For more information, see Update the minor version.
