Abstract:
A technique for managing a read cache in an eventually-consistent data store includes, in response to a read request for a specified data element, receiving the specified data element from the read cache as well as a remaining TTL (time to live) of the data element, as indicated by a timer for that data element in the read cache. If the remaining TTL falls below a predetermined value, the technique triggers an early refresh of the specified data element, prior to its expiration. Consequently, later-arriving read requests to the same data element that arrive before the data element has been refreshed experience cache hits, thus avoiding the need to perform their own time-consuming refresh operations.

Claim (Index 1):
A method of managing a read cache for an eventually-consistent data store, the method comprising:\n directing the read cache to store multiple data elements backed by persistent storage, the read cache configured to invalidate each of the data elements upon expiration of a respective timer provided for the data element; issuing, by a software application running on a server computer, a read request to the read cache to read a specified data element, the read request returning (i) the specified data element and (ii) a remaining TTL (time to live) of the specified data element in the read cache as indicated by the timer for the specified data element; performing, by the software application, a testing operation configured to (i) produce a first result in response to the remaining TTL of the specified data element being less than a predetermined value and (ii) produce a second result in response to the remaining TTL for the specified data element being greater than the predetermined value; and in response to the testing operation producing the first result, issuing an early-refresh instruction to the read cache, the early-refresh instruction configured to refresh the specified data element with fresh contents from the persistent storage prior to expiration of the timer for the specified data element.
