You are designing a Windows Azure application that will use Windows Azure Table storage. You need to
recommend an approach for minimizing storage costs.What should you recommend?
A.
Use Entity Group Transactions.
B.
Use multiple partitions to store data.
C.
Use a transaction scope to group all storage operations.
D.
Use Microsoft Distributed Transaction Coordinator (MSDTC).
Batch transactions are known as Entity Group Transactions (ETG) in Azure Storage; all the operations within an ETG must be on a single partition in a single table. Where possible, use ETGs to perform inserts, updates, and deletes in batches. This reduces the number of round trips from your client application to the server, reduces the number of billable transactions (an ETG counts as a single transaction for billing purposes and can contain up to 100 storage operations), and enables atomic updates (all operations succeed or all fail within an ETG). Environments with high latencies such as mobile devices will benefit greatly from using ETGs.
