Abstract
According to one exemplary embodiment, a method for remote direct memory access failover is provided. The method may include determining an RDMA operation will be performed. The method may include determining an available node. The method may include sending a data element to the available node based on the RDMA operation being an insert. The method may include receiving a pointer in response to sending the insert, whereby the pointer corresponds to a memory range. The method may include storing the pointer. The method may include retrieving the pointer based on the RDMA operation being an update, a read, or a delete. The method may include sending the pointer, the data element to the available node based on the RDMA operation being an update. The method may include sending the pointer and the RDMA operation to the available node based on the RDMA operation being a read or a delete.
