Hi HN,

I am the author of the open source spreadsheet Luckysheet. Luckysheet's github repository has won 6K+ star in 5 months. Thank you for your love.

This time we opened the java backend to support collaborative editing.

Demo - http://luckysheet.lashuju.com/demo/

1. After the user operates, the data is distributed quickly

2. Simple configuration, one-click Docker deployment

3. Support secondary development

4. Apache-2.0 License

Welcome to communicate if you have any questions :)

Great work!

How does the Java / Postgres application scale? How many concurrent users can it support?

It can be regarded as an ordinary docker application, and k8s is recommended. Postgres can split table by listid, but the database is not recommended to be installed with docker

Concurrency has not been tested yet

Very cool. congrats

Keep up the excellent work. Very cool! Congratulations!

Thank you for your attention. Luckysheet online DEMO is only for testing. Please be sure not to upload any uncomfortable content. Thanks again everyone

Ah,I saw a picture of Pornhub and it was uploaded to the spreadsheet!

What conflict resolving algorithm do you use? OT or CRDT? I didn't see it mentioned anywhere

In documentation it mentions it's using OT.

Congratulations on some incredible work, Alex. Are you considering going into the hosting business? Seems like a logical progression.

This is so very cool, why is it named lucky tho ? Just wondering.

It feels good, easy to say, good meaning

@alexliu518 do you have an example for a Vue.js + Node.js backend with simple saving and updating? Is this possible or do I need to run the Java backend + services?

There is no Node.js backend for the time being, we are considering plans for more backends in other languages

We have collected the backends of java, .NET and Golang versions provided by the community. Welcome to the community to provide another Node.js version.

Really impressive. Especially considering how small the developer team is.
