Any update on this issue?
We're running with some issues when we have multiple unused collections (we
indicated 'active' one with an alias and keep 2-3 old ones - per type and we
have 8 of those - as a emergency rollback possibility). In our case we'd like
to unload all in-active ones - that would give us tremendous memory saving...
EDIT 23/Mar/2020:
[~erickerickson] any chance for an update here?
This would help us big time really.

> Key: SOLR-6399
> URL: https://issues.apache.org/jira/browse/SOLR-6399
> Project: Solr
> Issue Type: New Feature
> Reporter: dfdeshom
> Assignee: Shalin Shekhar Mangar
> Priority: Major
> Fix For: 6.0
>
>
> There is currently no way to unload a collection without deleting its
> contents. There should be a way in the collections API to unload a collection
> and reload it later, as needed.
> A use case for this is the following: you store logs by day, with each day
> having its own collection. You are required to store up to 2 years of data,
> which adds up to 730 collections. Most of the time, you'll want to have 3
> days of data loaded for search. Having just 3 collections loaded into memory,
> instead of 730 will make managing Solr easier.
