Abstract
An apparatus, system, and method are disclosed for dynamically allocating buffers during the execution of a job. A plan module sets a buffer allocation plan for the job using data access history that contains information about the number and nature of data access events in past executions of the same job. A buffer module allocates buffers during the execution of the job, and alters the buffer allocation to improve performance for direct access events for those portions of the job that the buffer allocation plan indicates have historically included predominantly direct access events. The buffer module alters the buffer allocation to improve performance for sequential access events for those portions of the job that the buffer allocation plan indicates have historically included predominantly sequential access events. A history module then collects data access information about the current execution and adds that information to the data access history.
