Summary: C library calls getaddrinfo unconditionally from zookeeper_interest Key: ZOOKEEPER-1998 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1998 Project: ZooKeeper Issue Type: Bug Components: c client Affects Versions: 3.5.0 Reporter: Raul Gutierrez Segales Assignee: Raul Gutierrez Segales Priority: Critical Fix For: 3.5.0 (commented this on ZOOKEEPER-338) I've just noticed that we call getaddrinfo from zookeeper_interest... on every call. So from zookeeper_interest we always call update_addrs: https://github.com/apache/zookeeper/blob/trunk/src/c/src/zookeeper.c#L2082 which in turns unconditionally calls resolve_hosts: https://github.com/apache/zookeeper/blob/trunk/src/c/src/zookeeper.c#L787 which does the unconditional calls to getaddrinfo: https://github.com/apache/zookeeper/blob/trunk/src/c/src/zookeeper.c#L648 We should fix this since it'll make 3.5.0 slower for people relying on DNS. I think this is happened as part of ZOOKEEPER-107 in which the list of servers can be updated. cc: [~shralex], [~phunt], [~fpj] -- This message was sent by Atlassian JIRA (v6.2#6252)
