Connecting to multiple databases

Question
Does this library support connecting to multiple databases? If so, how?
Background
We've been embracing event sourcing with journal systems for years. Our database now have accumulated ~8 million records in the journal table (we take a snapshot every 1000 records). Now, I'm exploring a way to perform database migration from MySQL to Oracle. To do so, I need to have connections to both databases. Is there a way to configure to connect to multiple databases?
You can copy the jdbc-journal
section from https://github.com/dnvriend/akka-persistence-jdbc/blob/master/src/main/resources/reference.conf
and you could rename this to e.g. mysql-jdbc-journal
. You can then load the plugin based on the mysql-jdbc-journal
.
This probably means that you must configure which actor uses what journal so I am not sure if that is really what you want.
If you want to write to two journals at the same time, then no, that is not supported.
