Inspiring. You release aspects really explained in texts and documentation. ----thanks.
Am looking for examples of how to load my csv data into mnesia. Theyare basically static data my application needs. any help will be appreciated

Hey, thank you very much!
Sorry for answering so late. What I would do would be something like this:

• Find a good CSV deserializing library; I didn't use one in Elixir, but there's a package called csv in Hex, I would investigate this first.
• Since you said this was static data, I would add an OTP Agent to my app supervision tree, that would load the data, and try to do a batch insert, depending on the size of the CSV.

For large files, it would be interesting to look at the Stream module of Elixir's standard library.

It's been a while since I used Mnesia, so I may miss something related to data unicity/persistency between app startups.
