I can’t answer that, but I have two other things to say:

(1) libmysqlclient supports automatic reconnection; you should check whether the Lua lib you are using exposes that functionality
(2) you should be extremely aware that talking to a database in a blocking way from within a Recursor script is unsupported, as the whole Recursor thread is paused while your script is querying the database and making a decision

Kind regards,
