How to change stream track?

[JoanIzquierdo]

I would like to change the stream track dynamically without losing any message. What's the best method for changing the track of a stream?

You must stop and restart the stream. If you want to do this in a script, using stream.running = False then start another filter stream.

Twitter's API does not include a way to change tracks dynamically for the same standard stream:

One filter rule on one allowed connection, disconnection required to adjust rule

As of right now, you'll have to use the enterprise PowerTrack API if you want to use a non-Labs endpoint to do so.

Otherwise, you'll have to create a new stream with the new track, as explained.
I'd recommend using stream.disconnect rather than manually modifying stream.running though.
See also the Missing data from disconnections section of the documentation for consuming streaming data.
