Thank you for proposing this simple setup. How do you "keep track of the last sync"? Do you somehow keep track of that inside Solr, or is it manual record keeping?

When one of the Solr servers goes offline for maintenance, how do you make it "catch up" with the other server when it comes online again? In other words, how do you keep the two servers in sync?
