The SELECT privilege allows users to retrieve or read data from tables. Users can run queries that fetch data, but they cannot modify, insert, or delete data unless they have the appropriate privileges.

The CREATE USER privilege grants the ability to create new users. Once a user is created, their privileges can be revoked, but the user cannot be revoked in the same way.

The default binary log format in MySQL is ROW. This format logs changes at the row level, meaning that individual changes to each row of a table are recorded. This approach provides more consistency and accuracy during replication, especially with complex queries.

The KILL privilege allows users to terminate queries or sessions initiated by other users. This is typically used by administrators to stop runaway queries or long-running processes.

The SHOW PROCESSLIST; command displays a list of active threads and queries currently running on the MySQL server. It is useful for identifying slow or problematic queries.
