Thanks to Drupal 8 new field storage architecture, we can read everywhere that we can use other database than Sql, for example MongoDb, to store fields data.
I have a custom entity with some custom fields which will have to store a lot of (small) rows in database. I want to use the Drupal Entity, as recommended, (fieldable, etc) to store my data, instead of using a custom table like I did before with Drupal 7.
I ask myself if it's possible to use another database storage than Sql ; like MongoDb for my specific entity. I read some example for Drupal 7 but I'm not sure how to do with Drupal 8. There is Mongodb module, about more or less ported to Drupal 8 but it's not very clear.
Thanks for your comments and your help.
