---------------------------
Summary: LogSegmentMetadataStore should only notify when the list
of log segments is updated
Key: DL-93
URL: https://issues.apache.org/jira/browse/DL-93
Project: DistributedLog
Issue Type: Improvement
Components: distributedlog-core
Reporter: Sijie Guo
Assignee: Sijie Guo
Fix For: 0.4.0
Currently it notifies the listeners not only when there is a change but also
when session expires. it would break the reada
head loop and cause readers have to wait until it is able to connect to
zookeeper again.
With this change, it would only notify when the list of log segments is
updated. If it disconnects to zookeeper, the listen
er won't be notified and it would keep reading from the log segments it knows.
