Adaptive resource allocation method and apparatus

A non-transitory computer-readable storage medium coupled to one or more computers and configured with instructions executable by the one or more computers to:

• determining a request time, an execution time, and a response time corresponding to a service statement executed by a database system during a time period, wherein the request time is a time at which the service statement was executed by the database system, the execution time is an amount of time allocated for execution of the service statement by the database system, and the response time is an amount of time that elapsed between the request time and a time at which execution of the service statement ended;
• identifying a time segment of the time period based on the request time;
• determining a service type associated with the service statement;
• and
• updating a resource quota for the time segment based on the service type, the execution time, and the response time for the service statement.
