Hi Everyone, 
 

 Today I wanted to add a column to a large MariaDb table and  the server died 
after 2 hours with a corrupt database file, which I could not repair. I was 
lucky(precautionary) so I the replication saved me.
 

 I learned that Mariadb&MySql creates a new table with the new column and 
copies the original table to it when adding a column, in most cases. I think 
this is awful for huge tables.
 

 How does Firebird do it internally?
 

 Sincerely
