📝 Walkthrough

Walkthrough

The PostgreSQL data writer now builds squirrel insert statements in chunks of 500 for relationships and attributes. Empty inputs return early. Existing conflict handling, subject normalization, and attribute JSON marshaling remain unchanged.

Changes

PostgreSQL batch inserts

Layer / File(s)	Summary
Chunked relationship and attribute writes internal/storage/postgres/data_writer.go	batchInsertRelationships and batchInsertAttributes return early for empty inputs and queue one squirrel insert per 500 records. Relationship conflict handling, subject normalization, and attribute protojson marshaling remain in place.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to b57ee
