Abstract
The disclosed computer-implemented method for maintaining cache coherency may include (1) receiving an indication of a revocation of a grant to an owner node of a shared lock for a data object owned by the owner node; (2) invalidating, in response to the indication of the revocation, a copy of the object in a local cache of the owner node; (3) receiving, while the requesting node holds a grant of an exclusive lock, a request from the requesting node to update the object in the local cache; (4) transmitting, in response to the request to update the object, a request for a shared lock for the object; (5) receiving an indication of a grant of the shared lock; and (6) updating, in response to the grant of the shared lock, the object in the local cache. Various other methods, systems, and computer-readable media are also disclosed.
