Also, the ability to replicate a database to another location, always useful for backup and disaster recovery, is being enhanced in a number of ways, said Tomas Ulin, Oracle's MySQL vice president of engineering.

Such work is being applauded in the MySQL community.

"From an engineering standpoint, Oracle is doing the best work on MySQL that's ever been done," said Baron Schwartz, chief performance architect at Percona, which sells an optimized version of the database software.
