4 months ago This plugin is not suitable as-is for streaming. While you could create multiple terrains, they will not line up without seams at the borders. You will have to modify shaders or the way normals are calculated, maybe pad heightmaps in some way so that they take into account neighbor terrains, or use a generation method that produces normals directly instead of running a second pass over a fixed chunk (because otherwise normals just repeat height values 1 pixel beyond the bounds, while it should take the neighbor's border pixel instead).
when should I use terrain_data.notify_region_change method
That method should be called after you're done editing terrain in a specific area during the current frame.
It would be better if there is a simple demo completing this feature
There is one, though quite old: https://github.com/Zylann/godot_heightmap_plugin/blob/master/addons/zylann.hterrain/doc/docs/index.md#procedural-generation
Also, it seems the title of your new issue doesn't actually match what you're asking. Because otherwise, there are many existing posts about generating terrain:

I think I can math the terrain node position to player position, meanwhile streaming the terrain heightmap according to the position. But is this method possible and will this method cause visual artifacts? And if it can be done in this way, when should I use terrain_data.notify_region_change method in real time?
