Abstract
Technologies for enabling remote direct memory access (RDMA) transport of serialized objects in streaming pipelines are described. One method of a first computing device that stores a serialized object in a first memory can generate a remote descriptor associated with the serialized object. The remote descriptor uniquely identifies the location of the serialized object and a reference count token. The first computing device sends the remote descriptor to a second computing device in the data center over a network fabric. The second computing device uses the remote descriptor to obtain the contiguous block from the first memory for storage at a second memory associated with the second computing device. The value of the reference count token can be updated by receiving a message from the second computing device, and the remote descriptor can be released responsive to the value of the reference count token satisfying a threshold value.
