Hello!
I'm thinking about two things:
1. what index is faster to scan (for select ... where statements) unique
or not unique ?
2. can the unique index to slow inserts commands (in comparison with not
unique index) ?
Best regards
Adam
Sorry for question. I've tested it by myself. There is no significant
differences.
