Inter-partition secondary index sample - Store several copies of each and every entity employing different RowKey values in different partitions in separate tables to allow quickly and successful lookups and alternate kind orders by making use of unique RowKey values.
The only real keys you might have are PartitionKey and RowKey. As an example, use compound vital values to enable alternate keyed accessibility paths to entities.
