Enabling stateless status checks using collector redirection

Abstract:

Systems and methods are disclosed for enabling stateless status checks using collector redirection. A pool of collector devices can enable asynchronous submission to a data collection system, whereby on receipt of data to a collector device, the collector device generates and acknowledgement value for the data. A submitting device can later use the acknowledgement value to obtain the status of processing the data on the collection system. If collector devices are load balanced, operation of a load balancer can cause a request for status to be routed to a different collector device than the device to which data was initially submitted. To address this, collector devices can be configured to use the acknowledgement value to identify another collector device to which data was originally submitted, and to forward status requests to that other device. Status requests can thus be correctly routed without modification to load balancer operation.
