Multiple DataSource instances

Question

Is it less-than-ideal to have multiple DataSource instances when using JDBC?

If I have a base class that has various subclasses that all use a single static instance of DataSource (if it matters, I'm using the Postgres driver), I imagine that is ideal because there is a single source for them to get their connections and I'll see a bigger benefit from pooling connections.

The other option is to have each subclass have its own DataSource instance, which I imagine is not ideal.

Just my guess though. Any more info would help!

No, there's no good reason to have multiple DataSource instances if you only target a single database.
