Thanks for asking. I’m from Apache Cloudberry community.

I think there is a plan on integration with iceberg, you can take this for reference: https://github.com/apache/cloudberry/discussions/369. We are also discussing the new roadmap, FYI.

For the comparison between Cloudberry and Greenplum, you can refer to the comparison on this page: https://cloudberry.apache.org/docs/cbdb-vs-gp-features

Thanks @anonzzzies !

Hi, thanks for your suggestions. I cannot edit the title anymore.

> I don't think that Greenplum's closed source means your product has a chance!

Maybe you're right. The Cloudberry Database is just one alternative and option for the existing Greenplum users if they want to continue using it.

Now Greenplum source code repo is achieved, not closed source. You can still download its source code but it will not upgrade and cannot get the latest code from its GitHub.

As I know, Pulsar community is doing the work of removing ZooKeeper, this is a helpful link: https://github.com/apache/pulsar/projects/10

Also there's one related article: <Benchmarking Pulsar and Kafka - A More Accurate Perspective on Pulsar’s Performance>: https://streamnative.io/blog/tech/2020-11-09-benchmark-pulsa...

Welcome to join us! You can edit the wiki page to resign your work pages in GitHub and start translating. Any Questions, you can issue it in GitHub.

Welcome.

In addition to the above mentioned, we developed this application also want to dig much more excellent tech articles, views and open source projects by Chinese developers with community.

In this application, we also use some popular frameworks, such as [Bootstrap](1), [CodeIgniter](2) and so on.

Although, CSDN Geek may have a long way to improve and proceed. Rencently, I have created an [GitHub organization](3) for CSDN Geek. APIs will be open for community in the next step.

that's great.

um, Learning is always full of challenge.

> I wish your country would open more to people.

I am not in charge of CPP or PRC, but my country is becoming much more open just given a little patience :)

Yes. I saw the news from @ruanyf's Weibo message. In my opinion, HN is not only for westerners, also for Chinese and other region users, maybe global in other words. But HN Chinese Clones have much focus on local IT news and articles share.

Last, I'm sorry to give none comment about sW/SaaS business.

Good. I saw this news from Weibo...

Also you could submit it to geek.csdn.net and other Chinese HN products.

His first Weibo MSG said that:

> Hello China! Happy to be back in Beijing, announcing innovative new environmental programs. 你好，中国！很高兴再次来到北京，并宣布创新的环境新项目。http://www.apple.com/cn/pr/library/2015/05/11Apple-Announces...

That's great. Bless.

Just in a few hours, his Weibo fans has increased to 259816...

Many Chinese IT stars on Weibo forwarded his first Weibo msg and sent their welcome.

benchmark recently also performed a comparison of the following three NoSQL systems:

* Apache Cassandra * MongoDB * SequoiaDB

The test specifically focused on the in-memory performance of the three systems. The detailed result can be found in [bankmark-20141213-WP-NoSQLBenchmark]: http://www.bankmark.de/wp-content/uploads/2014/12/bankmark-2...

yeah, just too short.

It's hard for general users to use Linux desktop.

"Free" also can has a big cost.
