Hi,

For Liminal, I discussed with the team yesterday and actually I missed the 
"[RESULT]" vote email.
As I will take care of bootstrapping step (creating the resources), we don’t 
have anything to report much.

So, I kindly ask to report next month.

Thanks,
Regards
JB

Re: [RESULT][VOTE] Project proposal - Apache AgensGraph Extension

[Justin Mclean]

Hi,

I’m not seeing any bootstrapping going on for this new podling. Don't forget 
your first report is also due today.

Thanks,
Justin

[Proposal] Pegasus - proposal for Apache Incubation

[吴涛]

Dear Apache Incubator Community,

I'd like to open up a discussion about incubating Pegasus at Apache. Our 
proposal can be found at https://pegasus-kv.github.io/community/proposal and is 
also included below.

We are looking for possible Champion if anyone would like to volunteer. Thanks 
a lot!

Best regards
  Tao Wu

Pegasus Proposal

== Abstract ==

Pegasus is a distributed key-value storage system that is designed to be 
horizontally scalable, strongly consistent and high-performance.

- Pegasus codebase: https://github.com/XiaoMi/pegasus
- Website: https://pegasus-kv.github.io

== Proposal ==

Pegasus is a key-value database that delivers low-latency data access together 
with horizontal scalability, using hash-based partitioning. Pegasus uses 
PacificA protocol for strong consistency and RocksDB as the underlying storage 
engine.

We propose to contribute the Pegasus codebase and associated artifacts (e.g., 
documentation, website content, etc.) to the Apache Software Foundation, and 
aim to build an open community around Pegasus’s continued development in the 
‘Apache Way’.

== Background ==

Apache HBase was recognized as mostly the only large-scale KV store solution in 
XiaoMi Corp until Pegasus came out in 2015. The original purpose of Pegasus was 
to solve the problems caused by HBase’s two-level architecture and 
implementation, including high latency because of Java GC and RPC overhead of 
the underlying distributed filesystem, and long failover time because of single 
point of RegionServer and recovery overhead of splitting and replaying the HLog 
files.

Pegasus aims to fill the gap between Redis and HBase. As the former is 
in-memory, low latency, but does not provide a strong-consistency guarantee. 
And unlike the latter, Pegasus server is entirely written in C++ and its 
read-write path relies merely on the local filesystem.

Apart from performance requirements, we also need a storage system to ensure 
multiple-level data safety and support fast data migration among data centers, 
automatic load balancing, and online partition splitting.

After investigating lots of existing storage systems in the open source world, 
we could hardly find a suitable solution to satisfy all the requirements. So 
the journey of Pegasus begins.

=== Rationale ===

Pegasus is a mature and active project which has been widely adopted in XiaoMi. 
After the initial release of open source project in 2017, we have seen a great 
amount of interest across a diverse set of users and companies.

Our experiences at committers and PMC members on other Apache projects have 
convinced us that having a long-term home at Apache foundation would be a great 
fit for the project, to ensure that processes and procedures are in place to 
keep project and community ‘healthy’ and free of any commercial, political or 
legal faults.

=== Initial Goal ===

Move the existing codebase, website, documentation, and mailing lists to 
Apache-hosted infrastructure.
Work with the infrastructure team to implement and approve our code review, 
build, and testing workflows in the context of the ASF.
Incremental development and releases along with Apache guidelines.

== Current Status ==

Pegasus has been an open-source project on GitHub 
https://github.com/XiaoMi/pegasus since October 2017.

=== Meritocracy ===

The intent of this proposal is to start building a diverse developer and user 
community around Pegasus following the ASF meritocracy model. We plan to invite 
more people as committers if they contribute to this project.

=== Releases ===

Pegasus has undergone multiple public releases, listed here: 
https://github.com/XiaoMi/pegasus/releases.

These old releases were not performed in the typical ASF fashion. We will adopt 
the ASF source release process upon joining the incubator.

=== Code Reviews ===

Pegasus’s code reviews are currently public on Github 
https://github.com/XiaoMi/pegasus/pulls.

=== Community ===

Pegasus seeks to develop developer and user communities during incubation.

=== Core Developers ===

Currently most of the core developers of Pegasus are working in the KV-Storage 
Team of Xiaomi. Yingchun Lai is one of the Apache Kudu PMC members. Zuoyan Qin 
is an experienced open-source developer who created sofa-pbrpc in his last job 
in Baidu. Wei Huang is also an active contributor of Apache Doris (Incubating).

- Yuchen He (https://github.com/hycdong)
- Tao Wu (https://github.com/neverchanje)
- Yingchun Lai (https://github.com/acelyc111)
- Wei Huang (https://github.com/vagetablechicken)
- Shuo Jia (https://github.com/Shuo-Jia)
- Liwei Zhao (https://github.com/levy5307)

=== Alignment ===

Pegasus is aligned with several other ASF projects.

We are working on a new feature to load data from the HDFS filesystem. Pegasus 
can also generate and store checkpoints to HDFS, for both backup and analysis 
purpose. We currently support offline analysis on checkpoints powered by

[zhangguochen]

Hi Justin,

I am sorry for the delay feedback and thank you for your interest.
We have spent the time preparing more and working on HBlock. We would like
to enter the incubator but still need 2-more mentors to step forward.
Any volunteers to mentor HBlock and then we'd like a vote on our proposal to
start the journey to become Apache HBlock.

Best wishes.
Guochen.
