Firstly, what a way to extrapolate an entire article from the fact that a your engineering team is incapable of doing runtime validation.
Also brushing over the data validation side of things when this is the most important part about all of this and making out this is some clever engineering feat because you managed to have the equivalent of a write ahead log for your tables/cluster.
"when we're working with external systems, it's easy to find yourself in a situation where the types are lying to you"
No..this is your system...you show know the types of your own data..just wow.
