A data processing system for processing requests for features at a file collaboration platform implements receiving, at the file collaboration platform, a request from a client device to invoke a requested service on one or more files, wherein the requested service is associated with a feature provided by the file collaboration platform; determining a current operating status of the file collaboration platform; obtaining a feature-specific policy associated with the feature associated with the request; determining whether the requested service is allowed by the file collaboration platform based on the current operating status of the file collaboration platform and the feature-specific policy associated with the feature; allocating capacity to the request at the file collaboration platform for performing the request responsive to determining that the requested service is allowed; and sending a first message to the client device indicating that the client device may invoke the requested service.

Framework for allowing complementary workloads/processes to bring in heavy load on a file collaboration platform

The handling of external calls from one or more services to one or more subservices is described. Upon detecting that a service has made an external call to a subservice and prior to allowing the external call to be sent to the subservice, a system evaluates the external call against one or more pre-call thresholds to determine whether or not the one or more pre-call thresholds are met. If the determination is that a pre-call threshold of the one or more pre-call thresholds is not met, the external call is failed without sending the external call to the subservice. This failing might include communicating to the service that placed the external call that the external call has failed. Otherwise, the system sends the external call to the subservice. By applying these thresholds, the service is kept from using too many resources.
