Why Rebuild a Distributed Scheduler? Inside a Custom Java Job Framework

This article explains the motivations behind creating a new distributed scheduling framework, compares existing solutions, and details the design choices—including gRPC communication, protobuf serialization, a custom NameServer for load balancing, and a built‑in message queue with persistence and retry mechanisms—to handle frequent task creation and dynamic parameter changes in a high‑concurrency environment.

Analysis and Solutions for Load‑Balancing Issues in QLB‑4 Based TFServing Service Calls

The investigation of QLB‑4‑based TFServing calls revealed uneven traffic, stale routing after scaling, and idle servers due to layer‑4 hash routing, leading the team to replace QLB‑4 with a Consul‑driven client‑side load‑balancer that dynamically pools servers, eliminates restarts, and cuts GPU waste.

Memory Leak Diagnosis and Fixes for TensorFlow Serving in iQIYI’s Deep Learning Platform

The iQIYI deep‑learning platform identified two TensorFlow Serving memory‑leak problems—a string‑accumulating executor map caused by unordered input maps and an uncontrolled gRPC thread surge under heavy load—submitted upstream patches that sort inputs and cap thread counts, eliminating OOM crashes and stabilizing production.

Investigation of Goroutine Leak in Go

The article details how a sudden surge in goroutine and heap usage was traced to repeatedly creating gRPC clients instead of reusing a singleton, leading to blocked goroutines and TCP connections, and explains using pprof, stack traces, and tools like goleak to detect and prevent such leaks.
