Optimizing Distributed Database Sorting: In-Memory Merge to Disk Buffering

This article examines the challenges of sorting queries in distributed databases, outlines the limitations of in‑memory proxy sorting, and presents a step‑by‑step optimized approach that leverages per‑shard sorting, disk‑based buffering, and priority‑queue merging to reduce memory pressure and I/O overhead.

Optimizing Distributed Database Sorting: From In‑Memory Merge to Disk‑Based Priority Queues

This article examines the challenges of ordering results in distributed databases and presents a step‑by‑step optimization that moves sorting from proxy memory to disk‑based priority‑queue processing, reducing memory pressure, disk I/O, and network waste.
