What are the best practices for indexing in Sequelize?

When indexing in Sequelize, consider the following best practices: use composite indexes for multiple columns, avoid over-indexing, and analyze query performance.

Can you explain why over-indexing is a problem?

Over-indexing can lead to increased storage costs and slower write operations, as each index must be updated on data changes.

What tools can I use to analyze query performance?

You can use tools like Sequelize's built-in logging, database-specific tools like EXPLAIN in PostgreSQL, or performance monitoring tools.

How do I create a composite index in Sequelize?

To create a composite index in Sequelize, you can define it in your model like this: indexes: [{ fields: ['column1', 'column2'] }].
