Django ORM vs Raw SQL in 2025: When to Drop Down and Why

๐Ÿ›  Your Django app is slow. Do this before reaching for Raw SQL:
โœ… Add indexes to WHERE-heavy fields
โœ… Use select_related() / prefetch_related()
โœ… Cache expensive queries with Redis
โœ… Let the DB do the math: annotate(), aggregate()
โœ… Send thousands of rows at once with bulk_create()

๐Ÿ“‰ When ORM hits the wall, Raw SQL wins at:
โ€ข Complex joins, window functions, geo-batching
โ€ข Mass updates & deletes (millions of rows)
โ€ข Vendor tricks: PostGIS, UNNEST, JSON_TABLE
โ€ข Fine-tuned EXPLAIN-based optimization

๐Ÿง  Takeaway:
Use ORM for safety, clarity, and 90% of work.
Use Raw SQL for speed, control, or edge cases โ€” but wrap in tests and sanitize inputs.
