title: How do I keep a running count in DynamoDB without a hot table row?
body: <p>We have a completely server-less architecture and have been using DynamoDB almost since it was released, but I am struggling to see how to deal with tabulating global numbers on a large scale. Say we have users who choose to do either A or B. We want to keep track of how many users do each and they could happen at a high scale. According to DyanamoDB best practices, you are not supposed to write continually to a single row. What is the best way to handle this outside using another service like CouchDB or ElastiCache?</p>
