Entity group transactions in Azure Table Storage enable batch processing of multiple operations within a single partition. They improve performance and ensure atomicity, as all operations either succeed or fail together.
A use case for entity group transactions is an e-commerce application where customers place orders with multiple items. When an order is placed, the system needs to update inventory levels, create order records, and adjust customer account balances. These updates must be consistent; if one operation fails, all should be rolled back to maintain data integrity.
Example:
// Create a new batch operation
TableBatchOperation batchOperation = new TableBatchOperation();
// Add entities to the batch operation
batchOperation.Insert(new OrderEntity("PartitionKey", "Order1"));
batchOperation.Insert(new OrderItemEntity("PartitionKey", "Item1"));
batchOperation.Insert(new InventoryUpdateEntity("PartitionKey", "Inventory1"));
// Execute the batch operation on the table
table.ExecuteBatch(batchOperation);
