@laochou OceanBase appears to be a commercial and, based on the version string, customized database service it's not appropriate to place specific code in to WordPress for this purpose.

The delete_expired_transients() function runs on an action of the same name. If users of this service need to modify how this function runs then a plugin can be created for the purpose. For more complex needs a custom database drop-in can be created.

If there are general benefits to this change then they can be considered for all WordPress installs.
