What are the best practices for indexing in Django?

When indexing in Django, consider using the db_index option in your model fields, and create indexes on fields that are frequently queried.

How do I create a composite index in Django?

You can create a composite index by using the indexes option in your model's Meta class. For example:

class MyModel(models.Model):
    field1 = models.CharField(max_length=100)
    field2 = models.CharField(max_length=100)

    class Meta:
        indexes = [
            models.Index(fields=['field1', 'field2']),
        ]

Are there any performance considerations I should be aware of?

Yes, while indexes can speed up read operations, they can slow down write operations. It's important to balance the number of indexes.

Can I use PostgreSQL specific indexing features in Django?

Absolutely! Django supports PostgreSQL-specific features like GIN and GiST indexes. You can define them using the Index class.
