VARCHAR(36) or CHAR(16) Binary: What's the Most Efficient Way to Store GUIDs in MySQL?

Efficient GUID Storage in MySQL Tables

When incorporating GUIDs into MySQL table structures, storage considerations arise. The question emerges: should GUIDs be stored as VARCHAR(36) or is there a more efficient approach?

While VARCHAR(36) accommodates GUIDs' lengthy string format, alternative methods offer space-saving benefits. Database administrators suggest exploring storage as a CHAR(16) binary to optimize storage space. This method packs the GUID into a compact 16-byte binary representation, significantly reducing storage requirements compared to the 36-character VARCHAR approach.
