| Using UUIDs as primary keys is usually not recommended for performance reasons: | ||
| indexes are slower and take more space (because UUIDs in binary format take 128 bits | ||
| instead of 32/64 bits for auto-incremental integers) and the non-sequential nature of | ||
| UUIDs fragments indexes. UUID v7 is the only variant that solves the fragmentation |
