Does RDS for MySQL Support Multiple Accounts?

Yes, RDS for MySQL supports multiple accounts. You can assign different rights to these accounts through authorization commands to control access to different tables. Each table can be controlled independently.

Multi-user access to tables does not directly affect performance, but concurrent access by multiple sessions increases system resource overhead. For maximum connections supported by each specification, see RDS for MySQL Performance White Paper.

For more details about MySQL permissions, see MySQL community documentation.
