Zhijun Fu created ARROW-2551: -------------------------------- Summary: [Plasma] Improve notification related code Key: ARROW-2551 URL: https://issues.apache.org/jira/browse/ARROW-2551 Project: Apache Arrow Issue Type: Improvement Components: Plasma (C++) Reporter: Zhijun Fu
This change addresses two issues in plasma notification code: # Currently plasma store uses recv_fd to receive the notification fd from client. As mentioned in comments from the code, this could cause plasma store to hang if client doesn't call send_fd. This particular change puts the notification fd in SubscriptionRequest to solve the problem. # When a client subscribes to plasma store, the store pushes notifications of existing objects to ALL subscribers - while in this case it just needs to push to the new subscriber. This change adds a new interface to push to a particular client. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
