Re: [any version] Removal of 1 minute crons
timestamped actions can be an option, yet it will increase the load more than crons, unless you close open connections, even though the load is higher than crons. One other option... are the mysql events :P
While this is true - not all servers have MySQL 6.* yet. The developers of MySQL strongly recommend that you do not use MySQL 6.* until there is a stable release.
