Microsoft Azure Data Fundamentals DP-900 Practice Question

Azure Table storage uses a composite primary key made up of the PartitionKey and RowKey values. The PartitionKey groups related entities so the service can route requests to the correct storage node, while the RowKey uniquely identifies the entity within that partition. Together, these two values allow an efficient point lookup. Other properties such as ETag or Timestamp are metadata fields and are not used as part of the primary key, and neither the PartitionKey alone nor the RowKey alone is sufficient to uniquely identify an entity across the table.
