Write a query to optimize cursor behavior in MongoDB

Question

Can you help me with code that is Write a query to optimize cursor behavior in MongoDB.

Answer 1

To optimize cursor behavior in MongoDB, you can use pagination, indexing, and projection to improve performance. Here’s an optimized query using pagination with .limit(), .skip(), and indexing:

Optimized Query for Efficient Cursor Handling

db.users.find(

  { age: { $gte: 25 } }, // Filter condition

  { name: 1, email: 1, _id: 0 } // Projection (return only necessary fields)

)

.sort({ age: 1 }) // Sorting by age in ascending order

.limit(10) // Limit results for pagination

.skip(20) // Skip first 20 records (for page 3)

.hint({ age: 1 }) // Force index usage if an index exists on `age`
