Answer
Best practices:
- Use projection via
Select() - Use pagination
- Avoid
ToList()on large tables - Optimize queries with indexes
Quick Answer
Large datasets with EF Core: use AsNoTracking() for read-only queries (no change tracking overhead). Stream results with AsAsyncEnumerable() and await foreach instead of loading all into memory. Use pagination (Skip/Take). Use raw SQL (FromSqlRaw) for complex queries that EF Core translates poorly. Enable connection resiliency for transient failures. Split large queries into batches.
