What is MongoDB indexing and why is it important?
MongoDB indexing is a data structure technique that improves the speed of data retrieval operations on a database. It's important because it allows for faster queries, which enhances application performance.
How do I create an index in MongoDB?
You can create an index in MongoDB using the createIndex() method. For example, db.collection.createIndex({ fieldName: 1 }) creates an ascending index on fieldName.
What are the different types of indexes available in MongoDB?
MongoDB supports several types of indexes, including single field, compound, multi-key, text, and geospatial indexes, each serving different use cases.
Can you explain the difference between a unique index and a regular index?
