Using the Big Pipe approach for listing pages that are driven by Solr Index We are working on a website where we might end up having thousands/lakhs of nodes. So we are planning on using Apache Solr for the listing pages as well. 

Having researched a little bit about Big Pipe I was curious if we can use the Big Pipe approach for listing pages that are driven by Solr Index and if Drupal 8 Search/Solr module already supports it.
What exactly do you want to achieve?

That you can scroll endlessly through your nodes and don't have to click on pager links?

That's not related to the big pipe stuff.

Instead, you'll need a views pager plugin for that, e.g. https://www.drupal.org/project/views_infinite_scroll. There is a Drupal 8 version but I haven't used it yet, so I don't know if it's stable.
