It’s an interesting question why we focus so much on algorithms that are mostly not used on a day to day basis, but the topic of persistence that’s everywhere and which is often only partially understood is far from being this prominent. I remember a stint in research, about data analytic non the less, where rarely anyone had a good grasp of SQL or any other way to persist data for that matter. It really puzzles me to this day. Might be me finding most ORMs to be harmful if used without understanding of the underlying technologies.

Be careful, 'persistent' is used with different meanings in different contexts. See eg https://en.wikipedia.org/wiki/Persistent_data_structure https://en.wikipedia.org/wiki/Persistent_data_structure and immediately notice the warning 'Not to be confused with persistent storage.'

  Thanks, I usually refer to them as immutable, haven't actually come across the term persistent for these, but seems sensible.

    Persistent data structures don't have to be immutable. (The Wikipedia article explains.) But immutable data structures are always trivially persistent.
