Build index entities within a different partition or table. Alternative #1: Use blob storage For the very first option, you produce a blob for every special past name, As well as in Each individual blob retail store an index of the PartitionKey (department) and RowKey (staff id) values for workers which have that previous name. When you incorporate or delete an employee you ought to make certain that the content material of your relevant blob is ultimately consistent with the worker entities.

In this regard, your alternative of PartitionKey and RowKey for modifying entities should really abide by comparable standards for your choice to assist issue queries because you would like to detect entities as effectively as is possible. You do not desire to use an inefficient partition or table scan to locate an entity in order to find the PartitionKey and RowKey values you'll want to update or delete it.
