The 2-Minute Rule for clearance

An optimum query returns an individual entity depending on a PartitionKey value and also a RowKey benefit.

You must usually totally examination the effectiveness of your software in these scenarios. A query from the table support may perhaps return a utmost of one,000 entities at a person time and could execute to get a highest of 5 seconds.
