Abstract
The present disclosure relates to systems, methods, and computer program products for keeping multiple caches updated, or coherent, on multiple servers when the multiple caches contain independent copies of cached data. Example methods may include receiving a request to write data to a block of a first cache associated with a first server in a clustered server environment. The methods may also include identifying a second cache storing a copy of the block, where the second cache is associated with a second server in the clustered environment. The methods may further include transmitting a request to update the second cache with the received write data, and upon receiving a subsequent request to write subsequent data, identifying a third cache for invalidating based on access patterns of the blocks, where the third cache is associated with a third server in the clustered environment.
