…By the way, when you say no one else has done that, uh, would you consider Neon, uh, to be on a similar path in terms of being sort of S3 first and, uh, separating the compute and storage? Yeah, I think what I meant with that is, uh, just build a completely new database. I don’t know if we were the first, like it was very much, it was, I mean, I, I hadn’t, I just looked at the napkin math and was like, this seems really obvious. So I’m sure like a hundred people came up with it at the same time. Like the light bulb and every invention ever. Right. It was just in the air. I think Neon Neon was, was first to it. And they’re trying, they’re retrofitted onto Postgres, right? And then they built this whole architecture where you have, you have it in memory and then you sort of. You know, m map back to S3. And I think that was very novel at the time to do it for, for all LTP, but I hadn’t seen a database that was truly all in, right. Not retrofitting it. The database felt built purely for this no consensus layer. Even using compare and swap on optic storage to do consensus. I hadn’t seen anyone go that all in. And I, I mean, there, there, I’m sure there was someone that did that before us. I don’t know. I was just looking at the napkin math and, and when you say consensus layer, uh, are you strongly relying on S3 Strong consistency? You are. Okay. So…
