Optimizing MongoDB Queries for Performance

Learn how to optimize your MongoDB queries for better performance, including indexing strategies, aggregation pipelines, and best practices.

Indexing Strategies

Single Field Index

db.collection.createIndex({ field: 1 });

Compound Index

db.collection.createIndex({ field1: 1, field2: -1 });

Query Optimization

1. Use proper indexes
2. Avoid large documents
3. Use proper projection
4. Implement proper caching
5. Use proper batch processing

Best Practices

• Monitor query performance
• Use proper error handling
• Implement proper logging
• Use proper connection pooling
• Optimize network latency

Conclusion

Proper optimization is crucial for MongoDB performance. Start with proper indexing and gradually implement other optimization techniques as needed.
