 Agenda:

• Discuss about Netty 4
• Discuss: Write/AddEntry failures beyond Ack Quorum responses are ignored by the client. Replication scans to detect these are expensive and NOT bullet proof. It just scans once a week, and just checks first and last entry in the segment, which may not be enough. Especially the case if bookie is up but certain ledger dir on the bookie got deleted or some other scenario where a under replicated hole can go undetected.
• Testing: Existing Junit tests doesn't come close to give confidence for any distributed storage systems. What kind of destructive, consistency, and constraint guarantee tests are done at Twitter/Yahoo? As a community what else we can do? Jepsen? Runway? What does community think? how can we improve this area?
• Discuss next release plan.

• BOOKKEEPER-1040) Use separate log for compaction - Salesforce used different techniques to address this problem, we can discuss.

• Salesforce started looking into having multiple entrylogs.
