ListenTCP 2.0.0

Description
Listens for incoming TCP connections and reads data from each connection using a line separator as the message demarcator. The default behavior is for each message to produce a single FlowFile, however this can be controlled by increasing the Batch Size to a larger value for higher throughput. The Receive Buffer Size must be set as large as the largest messages expected to be received, meaning if every 100kb there is a line separator, then the Receive Buffer Size must be greater than 100kb. The processor can be configured to use an SSL Context Service to only allow secure connections. When connected clients present certificates for mutual TLS authentication, the Distinguished Names of the client certificate's issuer and subject are added to the outgoing FlowFiles as attributes. The processor does not perform authorization based on Distinguished Name values, but since these values are attached to the outgoing FlowFiles, authorization can be implemented based on these attributes.
