Minutes:

  • Yahoo merge: very close to the end, Pulsar will be soon able to run on ASF version (Ivan)
  • Salesorce SalesForce merge: very close to Apache version (JV, Sam is working on this)
  • Enrico: documentation for 4.7: documentation .0 ? but which features are interesting ? Maybe support for Java 9 and DBLedgerStorage. Ivan reports that DBLedgerStorage may not work well on current version (no one ever used it in this form)
  • Enrico: code coverage Code Coverage status, very close to have a good starting point,  will commit JaCoCo configuration upgrade soon, most of the work will be in 4.8 release
  • JV: BK is not very CPU friendly, buffer copy 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 CPUUsing Flame Graphs may help to see the hotspots.
