Joe Wang created ZOOKEEPER-2605:
-----------------------------------
Summary: Snapshot generation fills up disk space due to high
volume of requests.
Key: ZOOKEEPER-2605
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2605
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.4.5
Reporter: Joe Wang
Priority: Minor
Not sure if it's a bug, or just a consequence of a design decision.
Recently we had an issue where faulty clients were issuing create requests at
an abnormally high rate, which caused zookeeper to generate more snapshots than
our cron job could clean up. This filled up the disk on our zookeeper hosts and
brought the cluster down.
Is there a reason why Zookeeper uses a write-ahead log instead only flushing
successful transactions to disk?
