The user must ensure that the FlowFile content being fed to this processor is not larger than the maximum size for the underlying UDP transport. The maximum transport size will vary based on the platform setup but is generally just under 64KB. FlowFiles will be marked as failed if their content is larger than the maximum transport size.</p><h3>Tags: </h3><p>remote, egress, put, udp</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.
