Working on it...

@DanielFran I'm having a solution for Elasticsearch, but that's really complicated

[jdubois]

I started implementing is in jdubois@25f1acb

My main blocker at the moment is that this returns a Stream of objects, so this won't work with pagination. Maybe we need to remove pagination for Elasticsearch, as it's a stream?

@DanielFran you also did a big part of the work here! It's such a huge PR, it should have been $500 anyway, let me update it. -> how about you get $200 and I get $300?

[DanielFran]

Ok for me, many thanks! 👌

[jdubois]

That's normal! And I might not claim the money, but expense some stuff I need for streaming - I feel bad taking money here

[jdubois]

$300 is about 250 Euros, I'll expense the latest computer stuff I bought for that amount (cc @pascalgrimaud @deepu105 ) as at least I'll use them for JHipster
