The paper Feral Concurrency Control: An Empirical Investigation of Modern Application Integrity uses the term "feral" in a way I have never seen before.
Rails has developed a range of concurrency control strategies, two of which operate external to the database, at the application level, which we term feral concurrency control mechanisms.
The paper shows that various application-level data validations are less reliable than database-level checks.
The only usage of "feral" I'd seen previously applied to untamed animals - eg, "feral cats".
Are the authors using the term disparagingly, or does "feral" mean something different in this context?
