MySQL, here and here. So, since I have been working with MySQL for a while, here is my list:
- File per table backup mode for mysqldump that would work with --single-transaction flag
- Clustering without the NDB in memory storage
- Ability to turn logs (query, binary, slow queries) on and off without restarting
- Ability to setup log filters (such as log queries using particular table into a separate file or log queries scanning more then 10K rows)
- Ability to use bound variables in prepared statements properly (such as use variables in LIMIT or pass table names in the variables)
- Proper implementation of views (proper, as in not involving running a select every time a view is queried)
