(Only available if Keep Connection Active is enabled)
This is the maximum number of connections that Flow will create and keep cached. When Flow first uses the connection it will create Min Connection number of connections. As Actions need the DB Connection they will use them from the cache, potentially creating up to Max Connections. Once the Action has finished using the connection, it will remain connected and be returned to the cache available for the next Action that needs it.
This option allows you to control the maximum number of connections Flow will have to the database at any one time. Flow will never use more than Max Connections and multiple Actions are processing that require more connections, these Actions will be paused until a connection becomes free.
If Max Connections are created and stored in the cache they will eventually be freed and the cache return to storing only Min Connections. The cache is checked for unused connections every 10 minutes. Any connection that has not been used in that period will be closed.
