Hi, Do you have other clients than gitlab that run meltano at high scale?

To be clear, GitLab is not actually currently running Meltano in production. A number of people in this community are (e.g. https://meltano.slack.com/archives/CFG3C3C66/p1594123971493200), but I don't think I would describe anyone's usage as "high scale" just yet. We're explicitly in the phase where we know there are still many rough edges and limitations, that we can only resolve and move past through feedback from early adopters like yourself 🙂 See also https://meltano.com/blog/2020/05/13/why-we-are-building-an-open-source-platform-for-elt-pipelines/#where-meltano-fits-in

ok, nice.

We definitely want to support that, so your feedback would be (and already is) invaluable. Meltano might not quite be up to the task today, but we intend to get it there sooner rather than later, and you'll find that I (and the rest of the community) are very responsive to feedback and usually resolve issues quickly, especially if they're obvious 🙂
