Semantic Sharding and Distributed Query Planning
Can semantic metadata improve routing, pruning, and distributed plan selection?
Question and scope
partitioning rules for workspaces, tenants, types, sources, provenance, region, and time.
Research artifacts
partition model, routing metadata, distributed join choices, index locality, and materialization placement.
Evidence and evaluation
physical-only baseline, semantic-aware treatment, ablations, and cross-shard measurements.
Claim boundary
semantic knowledge eliminates cross-shard communication.
