Optimizing Distributed Database Sorting with Proxy Buffers and Priority Queues

This article examines the architecture of distributed databases, identifies the challenges of global sorting across shards, and presents both in‑memory and disk‑based proxy sorting solutions, detailing buffer configuration, merge‑sort and priority‑queue techniques, performance trade‑offs, and practical constraints for large‑scale queries.

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.
