Extensible and generic framework for managing resources for data warehousing loads

摘要

Methods, systems, and computer program products are provided for managing resources. A request is received for a plurality of resources from a requester. A ticket is generated for the request that indicates the resources. For each resource, a resource provider for the resource is queried to determine whether the resource can be acquired. The ticket is queued if any of the resources cannot be acquired. The ticket is granted if all of the resources can be acquired.

1. A method for managing resources implemented in at least one computing device, comprising:
receiving a request for a plurality of resources from a requester; generating a ticket for the request that indicates the plurality of resources; assigning a default priority for the ticket based on a determination that the request does not include a priority indication, the default priority being a priority that is greater than a low priority and less than a high priority; for at least one resource of the plurality of resources, querying a resource provider of a plurality of resource providers for the at least one resource to determine whether the at least one resource can be acquired; queuing the ticket in a queue if any of the resources cannot be acquired; instructing each resource provider to release any resources that were locked during said querying if a resource provider indicates that a resource cannot be acquired during said querying; and granting the ticket if all of the resources can be acquired.
