You can add users and databases from the DigitalOcean Control Panel. You must use a third-party client to manage access control lists (ACLs). Known Issues Managed Database Cluster Known Issues For example, you cannot migrate a managed database cluster from one DigitalOcean account to another. We do not currently support migrating managed database clusters on DigitalOcean to other managed database clusters on DigitalOcean. For example, max_connections for a 4 GB node is 401. Max_connections for a given node is one higher than the available backend connections for its plan, to accommodate an extra system process that does not count against the node’s connection limit. Usable memory is the total memory on the node minus approximately 350 MB of overhead for the operating system and management. MySQL nodes can have up to 75 (for plans under 4 GB) or 100 (for plans greater than or equal to 4 GB) simultaneous connections per gigabyte of usable memory, rounded down to the nearest gigabyte. You can’t edit them, but you can see what they are with SHOW VARIABLES. The MySQL system variables are set depending upon the size of the cluster’s Droplets. To maintain cluster stability, users cannot use the root user. You cannot change the storage engine for MySQL from InnoDB to MyISAM. See How to Restore from Backups for details.Ĭonnection pooling is not supported for MySQL.
