Joran from TigerBeetle!

Happy to answer any questions. And thanks to Dominik Tornow of Resonate for writing this up as a guest post! It was a little rule we had coined, to help people remember how to preserve consistency across different DBMS's, and I think Dominik gave (beautiful) voice to it.

This post clearly shows how separating the system of record from the reference, with strict ordering, helps ensure consistency without transactions. The focus on idempotent operations and correct sequencing is practical and vital for reliable distributed systems. Using checkpointing to guarantee eventual correctness even during failures is a smart approach.
