Share PerspectiveManager between multiple threads in Python?

[Y3NK]

Hello,

I am wondering if there's a way to communicate through an Perspective Table and maybe the PerspectiveManager between different python programs ?

• on program working as "server", with a PerspectiveManager and a table
• a second (or more) python program, from which it could read / write to the same table as from the first one (I guess it should pass through the get_table of the PerspectiveManager, but how retrieve the manager of the first program in the second ?)

The 2 programs would run on the same machine.

Have you an idea about how to get that working ?

Many thanks!

perspective-python comes with both a server (PerspectiveManager via tornado or other async server), as well as a client which you can use to connect via websocket to a local or remote Python server.

For extreme performance, there are more options for async cooperative GIL-less threading, a PR for true GIL-less multi-reader support, and I imagine it is quite easy to get Perspective to work via python's shared memory support in multiprocessing. However, none of this is necessary for multiprocessing with perspective - a simple Python client/server will perform quite well without any tweaks.
