Explain PartitionKey and RowKey in Windows Azure table

Answer:

PartitionKey : This property stores string values which identifies the partition that an entity belongs to. Partitions are integral to the scalability of the table. Entities with the same PartitionKey values are stored in the same partition.

RowKey : It's the primary key within the partition. This property stores string values which uniquely identifies Entities within a partition. A combination of PartitionKey and RowKey form the composite unique key identifier for an entity.
