Pre-caching data for use upon execution of program code

Abstract:

Systems and methods for processing requests to execute a program code of a user use a message queue service to store requests when there are not enough resources to process the requests. The message queue service determines whether a request to be queued is associated with data that the program code needs in order to process the request. If so, the message queue service locates and retrieves the data and stores the data in a cache storage that provides faster access by the program code to the pre-fetched data. This provides faster execution of asynchronous instances of the program code.
