Also /cc dev@bookkeeper.apache.org One of the goals in this PIP is about resource isolation or read priorities at bookies to support different classes of read requests. That's aligned with some general discussion about IO prioritization (between writes, reads and scan/catchup reads) in bookkeeper community. It would be good to get thoughts and inputs from people from bookkeeper community.
Resource Isolation - Read priorities at BookKeeper level - Bookies should be able to support different classes of read requests and prioritize regular consumers vs read requests coming from SQL queries - Queries from users or groups should not overly impact other queries from other users or groups - Sijie On Thu, Jul 19, 2018 at 2:09 PM Sijie Guo <guosi...@gmail.com> wrote: > Great writeup, Jerry and Matteo!
