Database vs. Object Storage for Large Files: A Scalability Deep Dive

Storing large files like photos and videos directly within a database, such as PostgreSQL or MySQL, can lead to significant performance and scalability issues. While convenient for small projects due to single-location management and transactional integrity, this approach inflates backup times, strains database connections, and degrades cache performance. A more scalable solution involves using object storage services like Amazon S3, where the database only stores a reference (like an object key or URL) to the file. This separation allows databases to focus on indexing and querying structured data, while object storage handles the bulk storage, durability, and integration with content delivery networks (CDNs) for efficient file access.
