You are troubleshooting a slice in Microsoft Azure Data Factory for a dataset that has been in a waiting state for
the last three days. The dataset should have been ready two days ago.
The dataset is being produced outside the scope of Azure Data Factory. The dataset is defined by using the
following JSON code.

You need to modify the JSON code to ensure that the dataset is marked as ready whenever there is data in the
data store.
Solution: You add a structure property to the dataset.

You have a table named Table1 that contains 3 billion rows. Table1 contains data from the last 36 months.
At the end of every month, the oldest month of data is removed based on a column named DateTime.
You need to minimize how long it takes to remove the oldest month of data.
Solution: You implement round robin for table distribution.

You are monitoring user queries to a Microsoft Azure SQL data warehouse that has six compute nodes.
You discover that compute node utilization is uneven. The rows_processed column from sys.dm_pdw_workers
shows a significant variation in the number of rows being moved among the distributions for the same table for
the same query.
You need to ensure that the load is distributed evenly across the compute nodes.
Solution: You change the table to use a column that is not skewed for hash distribution.
