What are the best practices for indexing in Mongoose?

When indexing in Mongoose, consider the following best practices: 1. Index only what you need to improve performance. 2. Use compound indexes for queries that filter on multiple fields. 3. Monitor index usage and performance with tools like MongoDB Atlas. 4. Regularly review and optimize your indexes.

How do I create a compound index in Mongoose?

To create a compound index in Mongoose, you can use the index method in your schema definition. For example: schema.index({ field1: 1, field2: -1 }); This creates an index on field1 in ascending order and field2 in descending order.

What impact do indexes have on write performance?

Indexes can slow down write performance because every time a document is inserted, updated, or deleted, the indexes must also be updated. It's important to balance read and write performance based on your application's needs.

Can I remove an index after creating it?

Yes, you can remove an index in Mongoose using the drop method. For example: YourModel.collection.dropIndex('indexName'); Just make sure that the index is not being used by any queries before dropping it.
