"First quick doesn’t mean dirty, as long as we make the right choices." I love this, especially to make the right decision under lots of pressure.

Emm, sounds not good... this kind of incidents can impact not just developers but also business insight applications being heavily analyzing github activities and projects in real-time, like this one ( https://ossinsight.io/

I kind of agree, it may not be an apple-to-apple comparison if historical data are overlooked. Maybe another dimension to look at is to count the applications, but that can be very very hard...

Snowflake also announced their HTAP solution recently. Wondering how is Snowflake solution comparing to AlloyDB or TiDB.

Wow, didn't realize cool things like this once existed decades ago. So many information have been buried and lost in the history. Probably need a HUGE database to store all these kind of information before they lost...

I'm thinking about a website that exploit insights from the github data might be more useful, like this one: https://ossinsight.io/ , which can allow project owners, developers, or even investors to find out the projec

This is a fun project, however, what values can it provide besides fancy "social coding"? There are tons of information with github, and how to dig out the values behind sounds more meaningful to me.

emm... moving and rebuilding whole systems onto another cloud is another wallet-ache thing, but yes, things may change if everyone votes with their wallet. The reality is that the big players like Snowflake or Databricks can have more barga

What can everyone do before that "new cloud" happens? The approaches like the above post mentioned how their cloud database tries different things from technology side seems the right and practical way to pursue though.

This is great, and can definitely improve sort performance in database and big data projects. I can immediately imagine this is a perfect match to my project of columnar processing engine TiFlash ( https://github.com/pingcap&

Star can only show part of the truth, and a more comprehensive analysis may be needed to show popularity in multiple dimensions, like this website does: https://ossinsight.io/

Good points on performance side, but IMHO one of the pain points is still the memory management. Go GC can do some of the work, however it can be hard to do real-time tracking and management while this is exactly what db kernel needs.

Interestingly I have been thinking about related questions too ( https://news.ycombinator.com/item?id=31541200#31542407 ) Language wise, Rust might be a good choice as some projects like tikv already use it in a pretty larger

Thanks for sharing your great journey with these seemingly popular open source projects. You mentioned you chose Rust over Go when you started your storage project. Does that mean you would have chosen Rust if you start over a new database

Some examples: MySQL and PostgreSQL in C++: learning curve is long, hard to write good quality code for newbies; Presto in Java: GC of java is a "nightmare", hard to have subtle memory management; TiDB in Go: similar challenges to

Spanner usually handles transactional workload, but AlloyDB as HTAP may process the analytical workload at the same time, I think.

This is a good HTAP system for PostgreSQL ecosystem. Emm, what about a MySQL compatible HTAP system? An open source project ( https://www.vldb.org/pvldb/vol13/p3072-huang.pdf ) seems a good fit in this area that pro
