Modified consistency hashing rings for object store controlled WAN cache infrastructure

A computer program product for optimizing a wide area network caching infrastructure in a file based object storage architecture, the computer program product comprising:

• one or more computer-readable tangible storage devices and program instructions stored on at least one of the one or more computer-readable tangible storage devices, the program instructions being executable by a computer, the program instructions comprising:
• program instructions to create, by a parent partition, a heat map, wherein program instructions to create the heat map comprise determining a relationship between each partition of the file based object storage architecture based on a pattern of object recall per site per partition, and wherein each partition is wide area network caching enabled, and wherein the determined relationships identify the parent partition and the multiple dependent partitions;
• program instructions to prioritize prefetching by multiple dependent partitions based on the heat map;
• in response to prioritized prefetching by the multiple dependent partitions, program instructions to allocate wide area network caching threads;
• and
• program instructions to provide, by the parent partition, objects for prefetching by the multiple dependent partitions utilizing the allocated wide area network caching threads.

A computer system for optimizing a wide area network caching infrastructure in a file based object storage architecture, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more computer-readable tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, the program instructions comprising:
