-- Migration 10: Add indexes for source_insight and source_embedding source field
-- These indexes significantly improve performance of source listing queries
-- that count insights and check embedding existence per source

DEFINE INDEX IF NOT EXISTS idx_source_insight_source ON source_insight FIELDS source CONCURRENTLY;
DEFINE INDEX IF NOT EXISTS idx_source_embedding_source ON source_embedding FIELDS source CONCURRENTLY;

DEFINE FIELD OVERWRITE embedding ON TABLE source_insight TYPE option<array<float>>;
DEFINE FIELD OVERWRITE embedding ON TABLE note TYPE option<array<float>>;

-- delete orphan records
DELETE from source_embedding WHERE source.id=NONE;
DELETE from source_insight WHERE source.id=NONE;
