Subject Re: [DISCUSS] RocketMQ Incubation Proposal
Date Thu, 03 Nov 2016 22:42:07 GMT
Bruce,

While Willem and Luke are both foundation members, neither is on the IPMC.
That's easy enough to rectify if you can get them to send appropriate
emails out requesting membership.

I'm assuming the mailing lists will all be in the new format of
list@rocketmq.i.a.o

The RocketMQ github site mentions "Alibaba's MQ, also aliyun ONS.
http://www.aliyun.com/product/ons" Can you explain the relationship to
Aliyun ONS? (the link is dead)

I notice that the revision history is pretty sparse.  I'm assuming that it
was mostly maintained internal and not fully open sourced until recently?

I notice in the proposal that its mentioned RocketMQ doesn't integration
with existing Apache projects - but it currently declares dependencies on
Commons IO, CLI, Derby to name a few.  The only license that sticks out is
JNA, which itself has a weird licensing scheme.  Not a blocker for
incubation, but may require some trickery at release time.
