## Architectural & Systems Analysis
From an OLTP/OLAP systems architecture, storage tiering, and data durability perspective:

- **Zero-Vendor Lock-in Formats:** Leveraging open specifications (e.g. Parquet, Iceberg) ensures multi-engine interoperability without ingestion lock-in.
- **Vector & In-Memory Throughput:** Modern memory layouts and SIMD-accelerated execution pipelines minimize latency in real-time retrieval.
- **Distributed Resiliency:** Decoupled storage and compute layers enable elastic horizontal scaling with strict ACID guarantees.

## Impact on the Open Ecosystem
Empowers data engineers with open, self-hosted alternatives to monopolistic cloud database providers.
