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, a copy of the object in a local cache of the owner node, (3) releasing, in response to the indication, the grant of the shared lock, (4) receiving, after the releasing of the grant, a request from the requesting node to update the object in the cache, (5) transmitting, in response to the request to update the object, a request for a shared lock for the object, (6) receiving an indication of a grant of the shared lock, and (7) updating, in response to the grant of the shared lock, the object in the cache. Various other methods, systems, and computer-readable media are also disclosed.
