How to find out what actual location of data by its future?

[YarShev]

Is it possible to get data location (node IP) by its future?

from distributed.client import Client
client = Client()
future = client.scatter(1, hash=False) # How to detect node IP of the data (1) by its future?

Client.who_has will list the workers which are storing a Future

In [1]: from distributed.client import Client
   ...: client = Client()
   ...: future = client.scatter(1, hash=False) # How to detect node IP of the data (1) by its future?

In [2]: client.who_has(future)
Out[2]: {'int-2f2391b7c0024ea7bd8385aa140bfaea': ('tcp://127.0.0.1:53702',)}
