David Smiley commented on SOLR-6399:
------------------------------------

I _think_ this could be closed once SOLR-5750 (SolrCloud Collection Backup/Restore) is committed.  At least it addresses the use-case in the description.

> 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.
