Abstract: Methods and arrangements for providing cooperative caching in a distributed system. A cache and a communicator are provided at a node in a distributed system. The communicator is used to communicate with at least one other node with respect to related data stored at the node and the at least one other node, via: communicating a status of the cache at the node and receiving notification of a status of at least one cache of at least one other node. There is updated, upon communicating with the at least one other node, at least one of: a cache replacement policy at the node and a cache pre-fetching policy at the node. Other variants and embodiments are broadly contemplated herein.
