Abstract

See full text

The subject matter of this specification can be implemented in, among other things, a method that includes pre-registering, at a client device, one or more input/output (IO) buffers for a remote direct memory access (RDMA) interface at the client device. In response to pre-registering the one or more IO buffers at the client device, an application executed by the client device is provided with access to a distributed file system through the RDMA interface. In response to determining that data of a requested file in the distributed file system has been designated for caching, a first IO buffer among the IO buffers is designated as a cache for the data of the file. The data for the file is received via the RDMA interface and from the distributed file system, for the first IO buffer.
