How to create a new Ecto Adapter?

Hi,

I was thinking about creating a new Ecto Adapter for Apache Geode, as a way to learn something new about both Geode and Ecto and because I would like to use Geode in a Elixir project of mine.
The question is that I have been looking for some kind of documentation, tutorial o whatever documentations that could help me to figure out how to build a new Ecto Adapter… but with no success at all.

It would be great if someone could point me to any kind of help regarding this topic.

Thanks in advance…

This will give you some overview of the Ecto side of things, but not help with Geode.

If Apache Geode runs SQL, then you’re a lucky guy, and the resource given above will suffice I think.
Otherwise, you’re not so lucky because you’ll have to work with the entrails of Ecto.Query to translate them into the language you want to use.
When I wrote my own adapter, I look the adapter for Mnesia (ecto_mnesia) to have an idea of how to do things because, as you noticed docs is not so abundant.

Good luck!

Apache geode does not run SQL… in fact it is a kind of key/value store with a Rest interface. It has some drivers for java ( the language used to write Geode) and some others.

My intention was to write an adapter using the Rest interface.

Thanks for the resources … I have not seen the video yet, but I have read the article and does not get anything from there … Maybe the last one is the only one with some information regarding Ecto.

I was looking for some info regarding how Ecto adapters works and the interface to fulfill to write a new one for a new database.

I will review the articles after watching the video

Thanks for all the information :slight_smile:
