What are some effective indexing strategies in Sequelize?

In Sequelize, effective indexing strategies include using composite indexes, unique indexes, and full-text indexes. Composite indexes can improve query performance for multiple columns, while unique indexes ensure data integrity. Full-text indexes are useful for searching large text fields.

Can you explain how to create a composite index in Sequelize?

Sure! To create a composite index in Sequelize, you can define it in your model like this: indexes: [{ fields: ['column1', 'column2'] }]. This will create an index on both columns, improving query performance.

What are the benefits of using unique indexes?

Unique indexes prevent duplicate values in a column, ensuring data integrity. They also improve query performance by allowing the database to quickly locate records.

Are there any downsides to using too many indexes?

Yes, having too many indexes can slow down write operations, as the database needs to update the indexes whenever data is modified. It's important to balance read and write performance.
