[Maria-discuss] Are queries queued when locking a table?

Hello, Some backup tools make use of table locking to ensure data consistency during the operation. I'm wondering about what happens to the incoming queries for the table being locked. Obviously, the request will be pending until the table is unlocked but this way some timeout value may be reached. Another option could be to accept and queue all requests and replay them once the table is unlocked. So can you tell me how MariaDB is handling such situation. Is the second option (asynchronous request), can be activated within MariaDB? Best, Jimmy
