• python2.7 - trollius (unsupported)
• python3.4 - ignoring
• python3.6+ async/await, may use trio

• allow configuration of the floating point threshhold for "changed" locally and globally
• add support for serialization
• allow for distributed calculation
• Reuse expression in additional derived classes (https://stackoverflow.com/questions/41678621/how-to-rewrite-an-expression-in-terms-of-an-other-expression-in-sympy)

Basically instead of calling your subgraph when the parent is called, when the child is updates, it calls its parents

• websocket
• http
• socketio

A wrapper that, when asked, provides the next value if it exists, else provides the last value (so that multiple inputs need not tick at the same rate

• streamz
• mpipe
• pypeln
• aiostream (might be useful for async)

I see in #15 that you are already aware of us. https://streamz.readthedocs.io

We should compare notes and hopefully come up with something beneficial for all. I should note that streamz also has inputs from sockets/http/kafka and outputs to real-time graphics.

• tornado
• flask

• add ws output
• add socketio output
• Add last-value and/or rate-match generators (A wrapper that, when asked, provides the next value if it exists, else provides the last value (so that multiple inputs need not tick at the same rate)) added backpressure
• generate from sympy expressions
• support distribution
• redis

E.g in the option example, reuse the time value calculation in additional fields

• reuse node
• reuse expression
