I think I kind of agree with this.

One of the simpler supported backends for our Modality product (https://auxon.io/products/modality), which results in a data model that’s a special case of a DAG for modeling big piles of casually correlated events from piles and piles of distributed components for “system of systems” use cases, is built using SQLite, and the scaling limiter is almost always how efficiently the traces & telemetry can be exfiltrated from the systems under test/observation before how fast the ingest path can actually record things becomes a problem.

That said, I do love me some RDMA action. 10 years ago I was fiddling with getting Erlang clustering working via RDMA on a little 5 node Infiniband cluster. To mixed results.
