Subject Re: Solr support for multi-tenant applications

Indeed, it is all about the numbers. So, Danesh, what are your numbers -
number of tenants and number of documents per tenant. What is the expected
distribution curve of documents per tenant?

The only "limit" I would suggest is that you not have more than "low
hundreds" of cores/tenants.

Will tenants be directly accessing Solr, or will you provide them with a
REST API for an application layer that intermediates access to Solr?
