Zhijun Fu updated ARROW-2551:
-
Description:
There are a few issues in current Plasma notification code:
* When a client subscribes to Plasma, the store pushes notifications about
existing objects to ALL subscribers, while it should only push to the new
subscriber.
* And in the above scenario, it should only push "sealed" objects to the new
subscriber, while currently it pushes all objects regardless of the state.
* When a client disconnects, it will no longer be able to receive
notifications, thus the NotificationQueue for the client should be removed from
global map.
