Question:
You've been assigned a project where your task is to design an Azure function that activates automatically every 10 minutes. This function has to interact with a vast amount of unstructured data such as text or binary data from a source, perform necessary computations, and subsequently modify another source with the outcome. Now, in the context of this task, provide the appropriate triggers and bindings in the following code:
[FunctionName("ProcessData")]
public static void Run(
/* Triggers and Bindings here */
ILogger log)
{
// Read data from input
// Process the data
// Write the processed data to output
}
Answer:
To accomplish this, you could utilize a Timer Trigger for the Azure Function, enabling it to initiate every 10 minutes. This function could be configured with an input binding to retrieve data from the data source, in this case, Blob Storage, which is apt for handling unstructured data. Once the data processing is completed, an output binding to Blob Storage can be used to deposit the processed data.
[FunctionName("ProcessData")]
public static void Run(
[TimerTrigger("0 */10 * * * *")] TimerInfo myTimer,
[Blob("<container-name>/<blob-name>", FileAccess.Read, Connection = "BlobStorageConnectionString")]
Stream inputData,
[Blob("<container-name>/<blob-name>", FileAccess.Write, Connection = "BlobStorageConnectionString")]
Stream outputData,
ILogger log)
{
// Read data from input
// Process the data
// Write the processed data to output
}
