Data caching based on requestor identity

A data cache system, comprising:

• a data storage configured to implement a data cache and an item index for the data cache;
• a network interface configured to receive a content request for at least a data item;
• and
• a processor configured to:
• responsive to the content request, update a karma score corresponding to an originator entity of the data item in the item index, wherein the originator entity is a social network user account that uploaded the data item;
• compute a cache priority of the data item based at least on the karma score;
• in response to a cache wipe command, determine whether to discard the data item from the data cache based on the cache priority of the data item;
• in an event the data item is to be discarded, perform at least one of deleting the data item from the data cache or marking the data item for replacement in the data cache;
• and
• in an event the data item is not to be discarded, refrain from discarding the data item.

A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to:

• implement a data cache storing previously requested data items for a data cache system;
• responsive to a content request for at least a data item, update a karma score corresponding to an originator entity of the data item, wherein the originator entity is a social network user account that uploaded the data item;
• compute a cache priority of the data item based at least on the karma score;
• in response to a cache wipe command, determine whether to discard the data item from the data cache based on the cache priority of the data item;
• in an event the data item is to be discarded, perform at least one of deleting the data item from the data cache or marking the data item for replacement in the data cache;
• and
• in an event the data item is not to be discarded, refrain from discarding the data item.
