RowKey

Each row key is a unique identifier of a row within a partition (so you can have rows using the same RowKey column value as long they have a different PartitionKey). More importantly, each table is sorted in ascending using values of row keys. This requires a smart design when you need, for example, to read only a selection of the top rows and do not want to provide their row keys (we will cover that later in this chapter). Like PartitionKey, RowKey is also limited to 1 KB and has to be a string.
