PartitionKey

The PartitionKey is a sequential range of entities that have the same key value. The way that tables are partitioned is to support load balancing across storage nodes, where tables entities are organized by partition. It is considered the first part of an entity's primary key.

It may be a string value with a size of up to 1 KB, and every insert, update, or delete operation must be included in the partition key property.
