As per title I think Flow should have a connector for mySQL on-premise data via the Gateway like Power BI.
You can now read and write data in MySQL databases that are on-premises. You can read more here: https://flow.microsoft.com/blog/button-updates-seven-connectors/
MySQL is used for such a large number of business applications. A connector would really help with querying business data and generating alerts, workflow etc. To not have this connector will make this process much more complex.
It would be great if flow as well as powerapps would be able to connect to MySQL real time and event (e.g. new row in MySQL table could tricker a flow
MySQL should have at least a trigger for when a new row is created. It´s nonesense that thes ir not a trigger yet. Besides that, Flow is genious.
MySQL is such a common database, including this connector and some basic triggers should have already been part of Flow. I have a front-end built on the Joomla CMS which writes to MySQL. I need to be able to use it within Flow.
