= RocketMQ Proposal =

== Abstract ==

RocketMQ is a fast, low latency, reliable, scalable, distributed, easy to
use message-oriented middleware, especially for processing large amounts of
streaming data.

== Proposal ==

RocketMQ provides a message model including both pub/sub and P2P and it
supports both reliable FIFO and strict sequential message queues. It also
has the ability to accumulate a billion messages in a single queue,
provides mobile, internet-friendly protocols such as MQTT and HTTP.
RocketMQ also supports the ability to load data into Apache Hadoop for
offline storage or to handle stream processing for Apache Storm.

== Background ==

RocketMQ was developed at Alibaba in 2011 and has been used in production
there since that time. It can process the large amounts of events generated
by various systems and provides a common repository for many types of
consumers to access and process those events. RocketMQ also handles dozens
of types of events including trade order process, search, social network
activity stream and data pipeline. Every day at Alibaba, RocketMQ clusters
process more than 500 billion events. The Alibaba Group also uses RocketMQ
to provide message services for more than 3000 core applications.

RocketMQ was developed to meet Alibaba's particular use cases to provide
low latency message delivery and high throughput message sending. Alibaba
has also created its cornerstone product derived from RocketMQ, a Platform
as a Service (PaaS) product named the Alibaba Cloud Platform (
https://intl.aliyun.com/).  More than 100 companies use the RocketMQ open
source version today. We believe RocketMQ can benefit more people so, we
would like to share it via the ASF and begin developing a community of
developers and users via The Apache Way.


== Rationale ==

As background description, many organizations can benefit from a low
latency, reliable, high throughput, distributed platform. Its usage is
varied and we expect many new use cases to emerge. RocketMQ provides many
features to support many use cases from enterprise application integration,
to web applications to the flourishing of IoT applications.

== Current Status ==

=== Meritocracy ===

The intent of this proposal is to start building a diverse developer and
user community around RocketMQ following the ASF meritocracy model. Since
RocketMQ was open sourced, we have solicited contributions via the website
and presentations given to user groups and technical audiences and have
received positive feedback and contributions including clients for C++ and
.NET. We plan to continue this support for new contributors and work with
those who contribute significantly to the project to encourage them to
become committers.

=== Community ===

RocketMQ is currently being developed by engineers working for Alibaba
where it is highly used in a production environment. We also have active
users in or have received contributions from a diverse set of companies
including CMBC(China Minsheng Bank), Schneider Electric(
http://www.schneider-electric.com/), the China Railway Ministry official
ticketing website, China Union, Sina, Umei (http://sh.jumei.com), Chinese
Academy of Sciences and many more. We hope to grow the base of contributors
by inviting all those who offer significant contributions and excel through
the use of The Apache Way. Contributions from outside of Alibaba are now
being received by the RocketMQ project, including a dashboard, the
flume-rocketmq module, the storm-rocketmq and more.

To further this goal, the project currently makes use of GitHub project
features as well as a public mailing list via Google Groups.


=== Core Developers ===

RocketMQ is currently being developed by engineers from Alibaba and
Yeahmobi: Xiaorui Wang, Von Gosling, Jiangwei Jiang, Xinyu Zhou, Zhanhui
Li. Xiaorui Wang, one of Alibaba MOM project owners is also the originator
of the RocketMQ project. He has rich experience with open source software,
as well as being active within the RocketMQ community. Von Gosling, another
MOM project owner at Alibaba and co-creator of the RocketMQ project, is an
active open source software committer and has been an active contributor to
several projects in Alibaba, Apache community and Google Code. Von also has
deep experience with performance tuning, distributed system design and
coding. Xinyu Zhou, Wei Zhou and Jinjixiang, They have rich experience in
distributed system design and performance tuning, especially in message
queue, big data, etc. Zhanhui Li, is a developer at Yeahmobi who has a
great passion for software engineering, especially in fields of distributed
system design and development. Longda, has been involved with several open
source projects released by Alibaba,especially jstorm project, which has
donated to apache.

=== Aligment ===

The ASF is the natural choice to host the RocketMQ project as its goal of
encouraging community-driven open source projects fits with our vision for
RocketMQ. The ASF is also the home to many other projects with which we are
familiar with and hope to integrate with RocketMQ including Apache Storm,
Flume and Hadoop. We believe that there will be mutual benefit by close
proximity to these and other projects.

== Known Risks ==

=== Orphaned products ===

The core developers currently work full-time on the RocketMQ project for
Alibaba. RocketMQ provides a critical internal infrastructure and has been
in production use at Alibaba since 2011, so there is no concern that it
will become an orphaned project.

=== Inexperience with Open Source ===

The core developers are all active contributors, users and followers of
open source. They are all already committers and contributors to the
RocketMQ Github project and several of them also have experience actively
contributing to open source projects. Though the core set of developers do
not have experience at the ASF, there are plans to onboard individuals to
the project who have ASF open source experience.

=== Homogenous Developers ===

The current core developers are from Alibaba and Yeahmobi but the goal is
to establish a vibrant developer community and we will actively encourage
new contributors.

=== Reliance on Salaried Developers ===

Currently, the developers are paid to work on RocketMQ for both Alibaba and
Yeahmobi. We look forward to building a strong community around the project
in order to encourage more contributors to join the project.

=== Relationships with Other Apache Products ===
RocketMQ is not currently integrated with any other ASF projects except for
several Apache Commons products, such as commons-lang, commons-cli, etc. As
a messaging server, it is mainly used to traditional publish/subscribe
scenario and demandingly high volume realtime transaction system that
tolerates no message loss. It uses java primitive file api and some jni
technology to custom-build storage desgin. More details about its storage,
please see the [[
https://github.com/alibaba/RocketMQ/wiki/how-to-support-more-queues|RocketMQ
Storage Design]]) The table below providing some context for simple
comparison to some other Apache messaging projects at the ASF such as
ActiveMQ and Kafka (apologies for the terrible MoinMoin table formatting,
its syntax is limited. For a much better formatted table, please see the [[
https://github.com/alibaba/RocketMQ/wiki/motivation|RocketMQ Github page]]).

=== A Excessive Fascination with the Apache Brand ===

While we respect the reputation of the Apache brand and have no doubt that
it will attract new contributors and users, our interest is primarily to
give RocketMQ a solid home as an open source project following an
established development model. More reason are provided in the Rationale
and Alignment sections.

== Documentation ==

Information about RocketMQ can be found on the Github project wiki [
https://github.com/alibaba/RocketMQ]

== Initial Source ==

RocketMQ has been under development at Alibaba since 2011. The source code
was opened up in 2012. It is currently hosted on Github using the Apache
License ([https://github.com/alibaba/RocketMQ/blob/master/LICENSE]).

== External Dependencies ==

RocketMQ depends on some Apache projects:

 * Commons Lang
 * Commons CLI
 * Commons Codec
 * Maven

and other open source projects (organized by license):

 * ALv2:
  * JNA
  * Netty
  * FastJson
  * Jackson

 * MPL
  * Javassist

 * MIT
  * Mockito
  * SLF4J
  * Bridge-method-annotation

 * EPL 1.0
  * JUnit
  * Logback


As all dependencies are managed using Apache Maven, none of the
external libraries need to be packaged in a source distribution.

== Required Resources ==

=== Mailing lists ===

 * rocketmq-private (PMC discussion)
 * rocketmq-dev (developer discussion)
 * rocketmq-user (user discussion)
 * rocketmq-commits (SCM commits)
