Hi, Sorry, but -1 Ideally, a discussion thread should be raised before the formal vote to see if there are any concerns about this.
1. `PMC` shall not be used in a podling for formal vote, use PPMC instead. 2. `According to the Apache voting process, we need at least 3 +1 votes from PMC members/Committers and more +1 than -1 votes in total.` This isn't true, only PPMC member vote casts. 3. Based on the relationship between bolt and velox, I think we need a clarification about the legal issues. 4. If we do reach a consensus later, for such a huge contribution, I insist that Intellectual property clearance - Apache Incubator <https://incubator.apache.org/ip-clearance/> also need to be done, before any code get merged in. 4. I'm wondering that this just increase long-term maintenance cost 5. Also, is bolt vendor-natural?
