NYC Systems

February 20th, 2025 Talks

We are excited to announce the first night of talks in the NYC Systems series! Talks are agnostic of language, framework, operating system, etc. And they are focused on engineering challenges, not product pitches.

We are pleased to have Arun Parthiban and Justin Moore speak, and glad to have Trail of Bits as a partner for the venue.

Optimizing Query Performance with Materialized Views at Datadog

Arun Parthiban is a Software Engineer at Datadog, working on the Cross-Product Queries team, where he builds query systems for Datadog's storage infrastructure. Previously, he was part of Datadog's Task Platform team, developing queues and schedulers.

Delivering a great customer experience requires fast, responsive user interfaces, which depend on low-latency query responses from data systems. As a result, optimizing query performance is a key priority for engineering teams. Various techniques can help achieve this, including query optimization, precomputing results, and caching data in memory or storage. One powerful approach is Materialized Views. In this talk, we’ll explore Datadog’s Materialized Views infrastructure and how it enhances query performance while keeping costs low.

Experiences with Semi-Formal Proofs

Justin Moore is the Head of Infrastructure at Antithesis, and is responsible for designing, deploying, and maintaining the cloud environments and core infrastructure services for the Antithesis platform. Over the last 25 years his career has spanned datacenter efficiency, civics and elections, and sports analytics.

Ensuring the correctness and security of infrastructure placed on the open internet is challenging to get right and easy to get wrong. Traditional code reviews can be insufficient to fully address this problem, while formal proofs of correctness can be complicated, time-consuming, and overkill. In this talk I will discuss our approach and experience of using semi-formal proof methods paired with modern programming language features to mitigate risks in the services which comprise our "virtual Trusted Computing Base".
