Distributed in-memory key-value (KV) stores are embracing the disaggregatedmemory (DM) architecture for higher resource utilization. However, existing KVstores on DM employ a semi-disaggregated design that stores KV pairs on DM butmanages metadata with monolithic metadata servers, hence still suffering fromlow resource efficiency on metadata servers. To address this issue, this paperproposes FUSEE, a FUlly memory-diSaggrEgated KV StorE that bringsdisaggregation to metadata management. FUSEE replicates metadata, i.e., theindex and memory management information, on memory nodes, manages them directlyon the client side, and handles complex failures under the DM architecture. Toscalably replicate the index on clients, FUSEE proposes a client-centricreplication protocol that allows clients to concurrently access and modify thereplicated index. To efficiently manage disaggregated memory, FUSEE adopts atwo-level memory management scheme that splits the memory management duty amongclients and memory nodes. Finally, to handle the metadata corruption underclient failures, FUSEE leverages an embedded operation log scheme to repairmetadata with low log maintenance overhead. We evaluate FUSEE with both microand YCSB hybrid benchmarks. The experimental results show that FUSEEoutperforms the state-of-the-art KV stores on DM by up to 4.5 times with lessresource consumption.
