sshd setPermanentTransferThreads functionality in Apache SSHD ( Transfer thread pool size)

Hello MINA team,

Enterprise Legacy SFTP server has the below api:

public void setPermanentTransferThreads(int permanentTransferThreads)

 
Set the number of permanent transfer threads. Once a socket has either been accepted or connected, the socket is registered with a transfer thread. This thread asynchronously performs all the IO for the socket. If all the permanent threads become fully loaded then additional threads will be created to handle additional connections and shutdown once they have no sockets to service.
 
Is there any API simliar to the same functionality in APACHE Mina sshd library? If not then how to achieve the same functionality in sshd
