Distributed deterministic database systems support OLTP workloads over geo-replicated data. Providing these transactions with ACID guarantees requires a delay of multiple wide-area network (WAN) round trips of messaging to totally order transactions globally.

This thesis presents Sloth, a geo-replicated database system that can serializably commit transactions after a delay of only a single WAN round trip of messaging. Sloth reduces the cost of determining the total global order for all transactions by leveraging deterministic merging of partial sequences of transactions per geographic region. Using popular workload benchmarks over geo-replicated Azure, it is shown that Sloth outperforms state-of-the-art comparison systems to deliver low-latency transaction execution.
