Streaming Model Cascades optimize semantic SQL queries by routing rows through a fast proxy model and delegating uncertain cases to an expensive oracle

advanced Published 2 Apr 2026
Action Steps
  1. Identify the semantic SQL queries that can be optimized using model cascades
  2. Implement a fast proxy model to route most rows
  3. Delegate uncertain cases to an expensive oracle model
  4. Monitor and adjust the model cascade to optimize quality metrics
Who Needs to Know This

Data scientists and database engineers on a team can benefit from this approach as it reduces the per-row inference cost of large language models, allowing for more efficient querying of data warehouses

Title: Streaming Model Cascades for Semantic SQL

Abstract:
arXiv:2604.00660v1 Announce Type: cross Abstract: Modern data warehouses extend SQL with semantic operators that invoke large language models on each qualifying row, but the per-row inference cost is prohibitive at scale. Model cascades reduce this cost by routing most rows through a fast proxy model and delegating uncertain cases to an expensive oracle. Existing frameworks, however, require global dataset access and optimize a single quality metric, limiting their applicability in distributed s
