RethinkDB 1.7: hot backup, atomic set/get, 10x insert performance improvement
10x insert performance improvement seems very small considering this simple benchmark someone did:<p><a href="http://stackoverflow.com/questions/15151554/comparing-mongodb-and-rethinkdb-bulk-insert-performance" rel="nofollow">http://stackoverflow.com/questions/15151554/comparing-mongod...</a><p><pre><code>  MongoDB: 0m0.618s
  RethinkDB: 2m2.502s
</code></pre>
Although as stated in that post, this is likely because of the different fsync() policies between the two databases.
