Pipelining is a method to stream the module code over the ssh connection straight into the interpreter without first writing it to disk. Connection persistence

Pipelining is a method to stream the module code over the ssh connection straight into the interpreter without first writing it to disk. Connection persistence is identical to openssh's controlpersist mechanisms to reduce the amount of setup/teardown on connections. The networking modules in ansible make use of paramiko for ssh, which could not take advantage of controlpersist. In ansible 2.3 we wrote a tool to emulate controlpersist for paramiko.
