 MySQL BLOB Field Type: Store Files in the Database or on Filesystem?

Deciding on MySQL BLOB Field Type: Storage Options for File Uploads

In the context of database design, choosing the appropriate field type for storing files can be a crucial decision. This article addresses the question of whether to use the MySQL BLOB (Binary Large OBject) field type for managing file uploads.

Benefits of MySQL BLOB Field Type:

  • Security: Storing files within the database ensures protection against malicious file types, preventing viruses or executable code from infiltrating the system.
  • Centralized Data: Maintaining data within a single database simplifies access control and ensures close association between records and their associated files.

Alternatives to BLOB:

Filesystem Storage: Alternatively, storing files in a specific folder structure outside the webroot offers advantages such as deployment simplicity and write access control. However, it necessitates a naming convention for referencing files in the database.

Performance Considerations:

While BLOB fields do not inherently affect performance, having large BLOBs can result in slower processing due to data caching requirements.

Filesystem vs. BLOB:

The choice between filesystem storage and BLOB depends on specific requirements. Filesystem storage may be suitable for deployments where server configuration is not a concern. It also provides easier access to files through the web server. However, BLOB storage simplifies permission management and enables straightforward handling of headers for caching and content types.
