How to Compute Mutual Friends for 100M Users in Seconds with Redis

This article breaks down the massive‑scale challenge of calculating mutual friends for hundreds of millions of users, analyzes data‑size, latency, and memory constraints, and presents three Redis‑based solutions—basic Set, bitmap, and a sharded architecture—complete with code snippets, performance numbers, and practical trade‑offs.

Large-Scale Distributed Reinforcement Learning Solution Based on TKE

The project replaces cumbersome manual management of thousands of heterogeneous CPU and GPU nodes for large‑scale reinforcement learning with a TKE‑based, containerized actor‑learner architecture that automates batch start/stop, provides elastic autoscaling, fault‑tolerant processes, shared model storage, and CI‑driven image deployment, cutting costs by up to two‑thirds while dramatically speeding experiment cycles.
