In an AWS RDS MySQL cluster, if you grant a login `CREATE TEMPORARY TABLE` permissions and they log into a **read-only node**, they will **not** be able to create temporary tables. The read-only node enforces the read-only status, which prevents any kind of write operations, including the creation of temporary tables, even though `CREATE TEMPORARY TABLE` is typically allowed in other circumstances on read-write nodes. 

Temporary table creation requires write access, and since the read-only replica is set up to deny any changes to the database, it won't allow this operation. You'd need to ensure the user connects to a read-write node to create temporary tables.
