How Uber Tuned GC to Boost Presto Cluster Stability

Uber runs over 20 Presto clusters serving more than 500,000 daily queries, but frequent full GCs and OOMs threatened stability; by analyzing G1GC behavior and adjusting IHOP, heap waste, free space, and young‑gen size on JDK 8 and JDK 11, they cut full GC occurrences by up to 80% and markedly improved overall reliability.

Using Tencent Cloud EKS Virtual Nodes to Solve CronJob Isolation and Scheduling Challenges

By offloading thousands of short‑lived CronJob pods to Tencent Cloud EKS serverless virtual nodes, Zuoyebang isolated them from online services, eliminated IP waste, achieved millisecond‑level parallel scheduling and sub‑3‑second startup, freed 10 % of cluster resources and cut scheduling costs by roughly 70 % while markedly improving cluster stability.
