title: Are multiple Google BigTable nodes required for high availability?
body: <p>We are trialing the use of BigTable and are doing a capacity planning exercise. We think one node will satisfy our needs in the early stages of our implementation and we add more as necessary later.
  My only question is, do we require more than one node in order to provide high availability? (My lack of understanding of what constitutes a &quot;node&quot; is obvious here, the answer to this question will help me to understand)</p>
