Ebay has built a GraphDB cloud service called NuGraph, which is based on JanusGraph. FoundationDB is chosen as the JanusGraph’s storage plugin, because of its high-performance and distributed transaction support. Jun Li and Hieu Nguyen from eBay present the GraphDB architecture, and focus on how they deploy and manage FoundationDB in Kubernetes, how they improve JansGraph query performance in a cross-data center environment, how they bulk load the graph into FoundationDB with its transactional support, and how they secure the 3-tier cloud service with limited security support from FoundationDB.
In this talk Anoop Koloth and Hanzhang Wang from eBay present how they managed to build a monitoring system and leveraged data generated from envoy clusters:
(1) Processing billions of hits served from different platforms from worldwide in real-time.
(2) Key Performance Indicators from Envoy ecosystem.
(3) Effective ML solution for proactive monitoring diversified eBay systems.
(4) Graph-based modeling and algorithms to deal with system complexity.
(5) Symbiosis and enhancement with existing SRE solution.
This discussion presents the evolution “People You May Know” (PYMK) to its current architecture. The focus is on various systems built along the way, with an emphasis on systems built for LinkedIn most recent architecture, namely Gaia, a real-time graph computing capability, and Venice an online feature store with scoring capability, and how LinkedIn integrates these individual systems to generate recommendations in a timely and agile manner, while still being cost-efficient.
Devon Energy has developed a solution that analyzes subsurface attributes and readings in order to predict the drill’s position. This solution which is built on Azure Databricks, scales to over a thousand cores in order to process a full well in one to two hours and uses graph and statistics libraries to help maximize oil and gas production.
