As RAG systems scale, the memory requirements for high-dimensional embeddings often result in a rapidly growing infrastructure bill. I recently conducted an empirical study to compare two primary paths for cost reduction: Quantization and Matryoshka Representation Learning (MRL).
The goal was to identify the "sweet spot" where we can slash the storage footprint while maintaining production-ready retrieval quality.
Key Results (384d Baseline):
* Scalar (int8): 63.7% reduction in storage footprint with 98.1% Recall@10 retention.
* MRL + Scalar: Truncating from 384d to 256d MRL with Scalar Quanti
