    disagree with the general message here on MySQL.

    MySQL is a very capable database. We have a system with around 300 tenants in a Saas environment on AWS that runs most tables on mariadb (MySQL...
  11. Re: Do I need a service, or would something simpler suffice - Part 2

    if you do use a system that simply queries the db constantly make sure to wait between queries.

    another issue may be if you have multiple managers that are running this applet.
