Parquet vs ORC Compression and Encoding Analysis

Sarah Lin • Published Oct 26, 2026

Overview & Executive Summary

Modern enterprise architectures and high-concurrency production clusters demand rigorous validation when deploying advanced systems. This research paper examines Parquet vs ORC Compression and Encoding Analysis within distributed production environments. As organizations scale their infrastructure to handle massive throughput, identifying bottlenecks in memory allocation becomes critical for sustaining predictable service-level objectives.

1. Architectural Topography & Control Plane

The underlying architectural topology relies on a decentralized control plane communicating via asynchronous message brokers and gRPC framing. By isolating the data plane from telemetry loops, we eliminate synchronization lock contention across worker threads.
