What is the maximum payload for a message from the edge device to Octave?

20 data points = 1 message. A data point may consist of content of various datatypes. The message may contain data of type integer, numeric, string, boolean and JSON. The edge device may send much more payload over several messages. The end user does not configure the message payload, the edge device and Octave work in sync to reliably deliver all telemetry in an efficient manner.
