Answer
Large deletes cause heavy logging, lock escalation, and blocking. Solutions:
- Batch deletes
- Partition switching
- Mark-and-archive patterns
Quick Answer
Delete large data in batches — DELETE TOP (10000) WHERE ... in a loop — instead of one massive DELETE. A single large delete holds locks for a long time, blocks other sessions, and generates a huge transaction log entry. Batching keeps transactions short, log growth manageable, and blocking minimal.
