K.}, title = {Eris: Coordination-Free Consistent Transactions using Network Multi-Sequencing (Extended Version)}, year = {2017}, month = {October}, abstract = {Distributed storage systems aim to provide strong consistency and isolation guarantees on an architecture that is partitioned across multiple shards for scalability and replicated for fault-tolerance. Traditionally, achieving all of these goals has required an expensive combination of atomic commitment and replication protocols -- introducing extensive coordination overhead. Our system, Eris, takes a very different approach. It moves a core piece of concurrency control functionality, which we term multi-sequencing, into the datacenter network itself. This network primitive takes on the responsibility for consistently ordering transactions, and a new lightweight transaction protocol ensures atomicity. The end result is that Eris avoids both replication and transaction coordination overhead: we show that it can process a large class of distributed transactions in a single round-trip from the client to the storage system without any explicit coordination between shards or replicas. It provides atomicity, consistency, and fault-tolerance with less than 10% overhead -- achieving throughput 4.5--35x higher and latency 72--80% lower than a conventional design on standard benchmarks.}, publisher = {University of Washington}, url = {http://approjects.co.za/?big=en-us/research/publication/eris-coordination-free-consistent-transactions-using-network-multi-sequencing-extended-version/}, edition = {Technical Report UW-CSE-TR-17-10-01}, number = {UW-CSE-TR-17-10-01}, note = {XMLSEC '02 Proceedings of the 2002 ACM workshop on XML security}, }
