Thanks,
William

Thanks David for the introduction.  Ariam, I am located in Fairfax so a
meeting in DC is more than possible.

Can I give you a call to coordinate?  If so, what's a good number to reach
you?

Re: UNICEF Open Source project- Apache Foundation

[Kevin A. McGrail]

Thanks Ariam,

I have a child with Autism so this is very interesting to me and I also
helped found the largest support group in the Washington DC area.  I
have done grants for curriculum to teach children with autism to swim
with Autism Speaks and I can talk intelligently about AT/PECS.  We also
just had our keynote from Cliff Schmidt at Amplio which has some
crossover.  Anyway, enough about me, I'd like to setup a call, nothing
long and talk about our incubator and how we work/what we do.

Regards,
KAM

Re: How to review so-called "binary releases"?

[Julian Hyde]

Sorry to be stupid, since apparently the answer has been repeated “several 
times already”. But in the real world podlings (and top-level projects) will 
put directories up for a vote that contain a mixture of source and binary 
artifacts.

A case in point. Suppose you were asked to vote on 
https://dist.apache.org/repos/dist/dev/incubator/crail/1.1-rc2/ 
 

I hear Justin say that he would open the -bin.tar.gz and check its L & N files. 
And he would check -bin.tar.gz.asc and -bin.tar.gz.sha512.

And Greg seems to be saying that he would ignore those files altogether, and 
vote solely based on the -src.tar.gz, -src.tar.gz.asc and -src.tar.gz.sha512.

Are both of these approaches consistent with policy?

Sharding-Sphere already has a very active community,  it's good to see
it will be part of Apache incubator.

Re: Mentors wanted for Apache Hivemall (Incubating)

[Koji Sekiguchi]

Hi Makoto,

I'd like to be a volunteer to help your project as a mentor.

I'm a committer/PMC member of Apache Lucene/Solr and OpenNLP and an ASF member.

Thanks,

Koji Sekiguchi

The Apache Hivemall project has only two active mentors and looking
for new mentors.

We are very appreciated if anyone would like to be a volunteer to help us.

Here below is the brief information about our project:

Apache Hivemall (incubating) is a scalable machine learning library
for Apache Hive, Spark, and Pig.

• Website: http://hivemall.incubator.apache.org/
• Github: https://github.com/apache/incubator-hivemall
• Teams: http://hivemall.incubator.apache.org/team-list.html
• Last podling report: https://wiki.apache.org/incubator/September2018

Recent talks by our PMC members:
• 
https://speakerdeck.com/takuti/apache-hivemall-query-based-handy-scalable-machine-learning-on-hive
(OSDC europe)
• https://www.slideshare.net/myui/introduction-to-apache-hivemall-v050-116293454
(ApacheCon North America)

We plan to have two more Apache releases in Incubator and willing
graduate Incubator in 2019.

Last but not least, I'm attending ApacheCon North America and give a
talk on Thursday 16:40 at Ballroom. So, it's welcome to join the
session to discuss about mentoring after the talk.
https://apachecon.dukecon.org/acna/2018/#/scheduledEvent/0cbf85b79b554dee6

Thanks,
Makoto

Hi,

Nice proposal, good to se that there’s already a community around the project 
and that it already have a diverse (company wise) group of committers, and that 
it already have the recommended number of mentors. Good luck in incubation.

Subject:  [DISCUSS] Sharding-Sphere incubation proposal



Dear Apache Incubator Community,

I would like to start a discussion about the incubation of Sharding-Sphere
at Apache.

Please accept the Sharding-Sphere podling into the Incubator.

We have 4 mentors, also we are welcome other volunteers to mentor us.

The proposal can be found at
https://wiki.apache.org/incubator/ShardingSphereProposal . Here is the text
of it:


= Abstract =
Sharding-Sphere is an ecosystem of transparent distributed database
middleware, focusing on data sharding, distributed transaction and database
orchestration. It provides maximum compatibility for applications through
Sharding-JDBC (a driver to implement JDBC) or Sharding-Proxy (a proxy to
implement database protocol).

= Proposal =
With a large number of end users, Sharding-Sphere has a fairly huge
community in China. It is also widely adopted by many [[
http://shardingsphere.io/community/en/company/|companies and
organizations]] as a solution to process their massive amounts of data.

We believe that bringing Sharding-Sphere into Apache Software Foundation
could advance development of a stronger and more diverse open source
community.

Dangdang submits this proposal to donate Sharding-Sphere's source codes and
all related documentations to Apache Software Foundation. The codes are
already under Apache License Version 2.0.

  * Code base: https://github.com/sharding-sphere/sharding-sphere

  * Web site: http://shardingsphere.io/

  * Documentations: http://shardingsphere.io/document/current/

  * Community: http://shardingsphere.io/community/

= Background =

Relational database hardly supports such huge amounts of data any more
which has increased rapidly in recent years, but for reason of technique
maturity, developers and DBAs still want to use it to persist core data.

Sharding-Sphere was open sourced on Github in 2016. At the very beginning,
Sharding-Sphere is just a JDBC driver for data sharding (name as
Sharding-JDBC) at Dangdang internal framework; now it offers data sharding,
distributed transaction and database orchestration. Besides JDBC, proxy to
implement MySQL database protocol is also supported at present.
Furthermore, our roadmap includes Proxy for PostgreSQL protocol, Sidecar
model, data repica and elastic data scalability function as well.

Due to the extension of project, we provide proxy model and sidecar model
in addition to JDBC model. Therefore, we rename it to Sharding-Sphere by [[
https://github.com/sharding-sphere/sharding-sphere/issues/788|a public
vote]], which refers to a sharding ecosphere with Sharding-JDBC,
Sharding-Proxy and Sharding Sidecar as its three sub-projects.

Sharding-JDBC has won the [[http://www.oschina.net/project/top_cn_2016|TOP
20 most popular open source projects in China 2016]].

= Rationale =

Relational database still plays a very important role on current
application system. The maturity of products and surrounding ecosystem, the
friendliness of its data query and developers' and DBAs' mastery of it,
cannot be completely replaced with other types of database in the near
future. However, current relational database cannot support cloud native
very well and it is not friendly to distributed system.

It is the ultimate goal of Sharding-Sphere, which manages the databases
scattering around the system, to make user use distributed databases as
simply as using a single one.

Without extra cost, Sharding-JDBC directly connects database with Java
application to get the best performance.

Sharding-Proxy is deployed as a stateless server and supports MySQL
protocol at present. In the paper [[
https://db.cs.cmu.edu/papers/2016/pavlo-newsql-sigmodrec2016.pdf|What??s
Really New with NewSQL?]], three types of NewSQL are introduced, among
which Sharding-Proxy is a Transparent Sharding Middleware.

Sharding-Sidecar can be understood as a data panel in Service Mesh. The
interaction between the application and the database provides a mesh layer.
The concept of Database Mesh is similar to Service Mesh, and it focuses on
how to connect data access applications to the database. Database Mesh will
set up a huge grid system between applications and databases. Applications
and databases need be placed in the grid system. They are all objects
managed by the meshing layer.

= Current Status =
== Meritocracy ==
