---------------------------------
Summary: Avoid using fuzzy snapshots.
Key: ZOOKEEPER-4874
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4874
Project: ZooKeeper
Issue Type: Improvement
Reporter: luoxin
Currently, ZooKeeper uses a fuzzy snapshot method that allows write requests to
continue processing while taking a snapshot. However, this approach does not
retain an instantaneous data view during the serialization snapshot, leading to
some issues( ZOOKEEPER-4846, ZOOKEEPER-3145). There is a need to optimize this
process in order to maintain a consistent and accurate data view.,
We can optimize the snapshot process by caching the change and applying it
after the snapshot is finished to avoid a fuzzy snapshot.
