Which logs all the info about LogIn, LogOut and LogIn Failure events.
Additional info that is logged:
- User name
- event type (LogIn, LogOut, LoginFailure)
- Event date\time\time with microseconds
- authentication type (same as for IDENTIFIED BY of CREATE USER statement)
- array of active settings profiles upon login
- array of active roles upon login
- array of changed settings with corresponding values
- client address and port
- interface (TCP\HTTP\MySQL\PostgreSQL, etc.)
- client info (name, version info)
- optional LoginFailure reason text message.
Added some tests to verify that events are properly saved with all necessary info via following interfaces:
- TCP
- HTTP
- MySQL
Known limitations
- Not tested against named HTTP sessions, PostgreSQL and gRPC, hence those are not guaranteed to work 100% properly.
* Add a codec Encrypted() for encrypting columns on disk
While this is implemented as a compression codec, it does not actually compress data. It instead encrypts data on disk. The key is obtained by executing a user-specified command at the server startup, or if it's not specified the codec refuses to process any data. For now the only supported cipher is 'AES-128-GCM-SIV'.

If you push data via Buffer engine then all your queries will be done
from one user, however this is not always desired behavior, since this
will not allow to limit queries with max_concurrent_queries_for_user and
similar.
