The number of connections used per node depends on how many concurrent threads issue database commands plus sub-threads used for parallel multi-node commands (batch, scan, and query). One connection will be used for each thread.
This field is ignored by asynchronous transactions since these transactions are already bound by asyncMaxCommands by default. Each async command has a one-to-one relationship with connections.
