The image shows the view of a single publisher. It shows the users table on the left side and two shards named shard 1 and shard 3 from the Remote KVStore on the right side. A NoSQL Publisher with ID (2,0) connects the two shards on the right to the users table on the left. A method named OnNext() is shown on the NoSQL Publisher. Additionally, a dotted line runs from the NoSQL Publisher to the shards in the Remote KVStore representing a checkpoint action.
