 The name of an underlying file that will be used to back the database.

 The database's configuration
- txn
- Type: BerkeleyDB..::.Transaction
 If the operation is part of an application-specified transaction, txn is a Transaction object returned from BeginTransaction()()(); if the operation is part of a Berkeley DB Concurrent Data Store group, txn is a handle returned from BeginCDSGroup()()(); otherwise null.
