Is the Solr endpoint still needed?

The metadata assessment Solr endpoint has not been available outside of the NCEAS domain for about 2 years now (via ufw rules to exclude outside access).

We had made the decision to discontinue efforts to have MetacatUI query this endpoint to aggregate assessment info to create D3 based graphics inside MetacatUI, due to data volume and resulting lag time between initiating a query and displaying a graphic.

Will we need to use Solr in the future to retrieve and aggregate assessment scores?

For reference, here is an example Solr document:

Possibly. We still need an API to download run-level scores and check-level scores, rather than individual reports. Let's talk about how the service will deliver both data for various collections and the graphics that go along with that.
