RNTuple: Where are we now and what’s next?

Hello, this is Florine from the ROOT team! Over the past year, I’ve been working as a technical student funded by ATLAS to evaluate and help further develop RNTuple. As you may already be aware, RNTuple [1] is currently being developed as the successor to TTree, and is projected to be used in Run 4. I imagine you might be wondering why there is a need for a completely new (TTree-incompatible) system, and what this looks like. That’s why in this blog post, I will try to answer this question, as well as give you an overview of the current status of RNTuple, what we’re still working on before its first production release (and what we will work on beyond this), and finally how you can already try it out!
