Interesting feature, I think we can learn from this in our product. IMO, it is still not safe even we know there are no queries running for this table. You may still meet a scenario that when you type `drop table`, another guy begins to run

I am very agree with some options of this blog. As the maintainer of the open source distributed database TiDB https://github.com/pingcap/tidb , we also face the same problem of choice. We have a community version, an

Gitea is very easy to use, but I find the Activity feature is a little slow. I experienced the "Try Gitea" service and migrated our TiDB repo https://github.com/pingcap/tidb to it. When I clicked the Activity

I have to say, this problem has not been well solved. But we've still been doing something: - We used gRPC with no compression before, and we tune an acceptable compression level to achieve a balance of performance and data volume. - I

Thanks so much for sharing this article, it reminded me of a fallacy before when we built TiDB cloud (a distributed database service) at first, the fallacy is Transport cost is zero . We deploy TiDB in three available zone(AZ) in one regio

we are building a similar tool https://ossinsight.io/ which saves nearly 45B events from GitHub and can let you get more powerful insights from the project, e.g here is the history insights for K8s https://api.

A similar tool may be https://github.com/cloudflare/ebpf_exporter but seems Rezolus uses less resource. The most interesting thing is that Rezolus is written in Rust, we may embed it in our project TiKV and let TiKV ca

Cool, I did this several years ago. You can check LedisDB or RebornDB. But now I switch to TiKV, hope you can support it later :-)
