Partition key and row key
The primary key of Azure Table storage tables has two parts as follows:
- Partition key: Azure Table storage records are classified and organized into partitions. Each record located in a partition will have the same partition key (p1 in our example).
- Row key: A unique value should be assigned for each of the rows.
A clustered index will be created with the values of the partition key and row key to improve the query performance.
