Why primary keys are VAR_CHAR type in OFBiz
- The performance overhead is minimal on modern database systems.
- Character strings give significant flexibility, especially when it is common to migrate data from other systems that have characters in their IDs.
- Being able to prefix IDs is used in a number of places in OFBiz, including prefixes for entire systems when data transfers between them are done to separate ID spaces.
