Fragola: low-latency transactions in distributed data stores

Abstract

As transaction processing services begin to be used in new application domains, low transaction latency becomes an important consideration. Motivated by such use cases we developed Fragola, a highly scalable low-latency and high-throughput transaction processing engine for Apache HBase. Similarly to other modern transaction managers, Fragola provides a variant of generalized snapshot isolation (SI), which scales better than traditional serializability implementations.
