Abstract
Described herein is a system and method for performing a clustered coherent cloud read cache without coherency messaging. At a cloud reader agent having a read cache, a request for a particular portion of data is received from a client. The request includes an identifier of the node making the request, a current time on the node making the request, a last stubbed time of the particular portion of data, and/or an identifier of the particular portion of data. When the particular portion of data is stored in the read cache of the cloud reader agent, the cloud reader agent can determine whether the cached particular portion of data is valid based, at least in part, upon the received identifier of the node making the request, the received last stubbed time of the particular portion of data, and/or, a stored time associated with the cached particular portion of data.
