This article demonstrates how to construct a knowledge graph from a 58,099‑character document using GraphRAG, measures the indexing time on an M2 PRO machine, and compares Global, Local, and Drift query modes, highlighting three scenarios where Local mode is unsuitable.
This article walks through GraphRAG’s retrieval phase, showing how knowledge‑graph entities, relationships, and community reports are assembled into a query context, comparing local and global modes with traditional RAG, and illustrating the process with a concrete “Age of Big Data” example.
This article explains how to optimize Hive query performance by configuring fetch task conversion, enabling local mode, using map‑side aggregation, handling COUNT(DISTINCT) efficiently, avoiding Cartesian joins, applying partition and column pruning, and setting dynamic partition parameters, with practical command‑line examples.
This article explains why a typical Deployment + LoadBalancer setup can experience downtime during updates, analyzes the pod lifecycle, endpoint synchronization, iptables/ipvs and SLB interactions, and provides concrete configuration steps—including readiness probes, preStop hooks, and Service traffic policies—to achieve zero‑downtime deployments.
