Hi, When migrating from mariadb 10.1 to 10.3 we noticed that the default value for lock_wait_timeout went from 1 year to 1 day. Although 1 day seems more reasonable than 1 year, it seems pretty high for a lock_wait. Does anyone know why this value is so high? Are there any rule of thumbs for a good timeout value that won't degrade the system and yet allow it to operate as intended? I know that part of the answer is "it depends on which operations your applications are doing". What I don't know is if beyond those applications, mariadb needs a specific timeout to function properly, for example, when doing a mariabackup or flushing tables. Is anyone else using a timeout value other than the default ones? My apologies for the naivete of this question. Thanks! --josé
