Harald Ng

I am a Ph.D. student at the Data Systems Lab, advised by Paris Carbone and Seif Haridi. My research focuses on optimizing how distributed systems perform replication and transactions by leveraging practical aspects such as workloads and network settings.

Outreach and Development

Creator and maintainer of OmniPaxos, a distributed replication library written in Rust. OmniPaxos hides all the complexities related to consensus replication and instead provides a simple log API. This lets users build highly available services in a way that is as simple as working with a local log.

OmniPaxos is actively taught in the courses CS 651 Distributed Systems at Boston University and ID2203 Distributed Systems, Advanced Course at KTH Royal Institute of Technology.
