The article by Andrew Berrien dives into the performance characteristics of different in-memory storage solutions for read-only scenarios in Elixir. The solutions examined include storing data in a module, utilizing :persistent_term, using public :ets tables, and managing state with GenServer. Each method's read speeds are benchmarked across different dataset sizes ranging from 10 to 10,000,000 rows. The results highlight that storing data in a module is the fastest but requires metaprogramming. :persistent_term is nearly as fast and simpler to use, while :ets tables provide good performance with additional query capabilities. GenServer is noted to be the slowest for read operations. The article concludes with advice for handling large datasets in-memory, emphasizing the suitability of :ets for large-scale data storage.
