Minutes:

  • Yahoo merge: very close to the end (Ivan)
  • Salesorce merge: very close to Apache version (JV, Sam is working on this)
  • Enrico 4.7: documentation ? but which features are interesting ? Maybe support for Java 9 and DBLedgerStorage
  • Enrico: code coverage status, very close to have a good starting point, 
  • JV: BK is not very CPU friendly, buffer copy is very bad, CompletableFuture waits and Netty waits during reads. Do we need locks around the Netty Channel ? Even just Scheduling Speculative Reads is expensive on the client. BookKeeper client is as expensive as application CPU
