Скачать или смотреть MongoDB Wildcard Index: My Approach to Indexing Unpredictable Data

In this video, I explore the power of Wildcard Indexes in MongoDB, a flexible indexing strategy that allows you to index fields without knowing their exact names in advance. This is especially useful for dynamic or semi-structured data models.

📌 What you’ll learn:

What a wildcard index is and how it works
How to create and use wildcard indexes ($**)
Use cases for indexing dynamic fields in documents
Performance considerations and best practices
💼 Why it matters:
In modern applications where document structures can vary, wildcard indexes provide a scalable solution for query optimization without rigid schema constraints. This video demonstrates how I use them to build flexible, high-performance systems.
