Answer
Use partitioning when:
- Tables contain hundreds of millions of rows
- Fast archiving is required
- Hot/cold data separation is needed
- Maintenance takes too long
Quick Answer
Use partitioning when: tables exceed 50-100GB and queries naturally filter on a date or range column, you need to archive/purge old data efficiently (partition switching is instant), or you want to separate hot and cold data across different storage tiers. Smaller tables rarely benefit enough to justify the complexity.
