When you say 2B docs on a single Solr instance, are you talking only one shard? Because if you are, you're very close to the absolute upper limit of a shard, internally the doc id is an int or 2^31. 2^31 + 1 will cause all sorts of problems.
But yeah, your 100B documents are going to use up a lot of servers...
