I was reading through your documents and found it very interesting and good. Currently I am building a spring boot application which acts like an infrastructure component. This can connect to multiple databases and execute the pre defined queries with dynamic parameters. Was planning to use ORM too in the same but as I can see the configuration is only through the xml file. I wanted to check if it is possible to configure multiple databases in runtime.
For SQL DB’s i am using c3 pool with mchange and I am able to connect multiple databases in runtime .
