Hi @wyxxxcat ,

You could enable your fork repo's Github Action and it will trigger ci pipeline inside your own repo without the upstream repo's permission.

It may accelerate your development and review process. 😁

Best Regards,
Edward

Hi @wyxxxcat ,

Thanks very much for your effort! 😊

I left comment for error message compalibility with redis. I think it's not mandatory for tdigest command and current messages are reasonable, but will be better to keep compalibility.

Other parts are LGTM.

Best Regards,
Edward

Let's merge it first. Improvement can happen in further PRs.
