Summary: Support WebSockets ping/pong keep-alive in Gremlin server
Key: TINKERPOP-1726
URL: https://issues.apache.org/jira/browse/TINKERPOP-1726
Project: TinkerPop
Issue Type: Improvement
Components: server
Affects Versions: 3.2.5
Reporter: Andy Davidoff
The ping/pong keep-alive system that is part of the WebSockets spec provides
for successful identification of a dropped connection from either end of the
connection.
Currently, the Java client successfully issues keep-alive pings and receives
pong replies from the server. Unfortunately, the server does not actively ping
clients, nor does it discover and react to dead clients when keep-alive fails.
This can cause pending client writes to lock up the server indefinitely when a
client spontaneously disconnects.
