Database-Outbound Connection Management

I have a translation thread that chooses routes based on trxids.  Each route detail specifies an outbound destination implemented with the database-outbound protocol.  We’ve defined several of these database-outbound protocol threads, one for each table, but all sharing the same connection properties.  I still have the following questions after browsing the Database-Outbound documentation page.

1. If all outbound-database protocol threads share the same process, will they also share the same connection?   Or does each thread maintain its own connection via a connection life cycle specified by the connection options on the protocol property panel?

2. Is connection pooling performed?  If so, where can we configure this?
