As you will see, your decision of PartitionKey and RowKey is fundamental to excellent table design. Each individual entity saved inside a table should have a singular mixture of PartitionKey and RowKey. Just like keys inside of a relational databases table, the PartitionKey and RowKey values are indexed to create a his explanation clustered index that enables fast appear-ups; nonetheless, the Table provider would not build any secondary indexes so these are typically the only real two indexed Qualities (a number of the designs described afterwards present home how you can perform all around this obvious limitation).
If In addition, you right here want in order to uncover an personnel entity based upon the worth of A further residence, including e-mail deal with, you need to use a less efficient partition scan to find a match. It is because the table support will not supply secondary indexes.
