Improve C client connection reliability by making it sleep between reconnect
attempts as in Java Client
-------------------------------------------------------------------------------------------------------
Key: ZOOKEEPER-906
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-906
Project: Zookeeper
Issue Type: Improvement
Components: c client
Affects Versions: 3.3.1
Reporter: Radu Marin
Currently, when a C client get disconnected, it retries a couple of hosts (not
all) with no delay between attempts and then if it doesn't succeed it sleeps
for 1/3 session expiration timeout period before trying again.
In the worst case the disconnect event can occur after 2/3 of session
expiration timeout has past, and sleeping for even more 1/3 session timeout
will cause a session loss in most of the times.
A better approach is to check all hosts but with random delay between reconnect
attempts. Also the delay must be independent of session timeout so if we
increase the session timeout we also increase the number of available attempts.
This improvement covers the case when the C client experiences network problems
for a short period of time and is not able to reach any zookeeper hosts.
Java client already uses this logic and works very good.
