I've Event trigger in Azure Data Factory, it triggers when a new blob is created in Azure Blob storage. But my trigger is not firing on Blob creation.
Followed below link but stuck at below mentioned point:
Azure Data Factory: event not starting pipeline.
Environment details:
Event Grid is registered, ADF is v2 and passing parameters to pipeline.
My question is do I need to have Azure storage event subscription activated? If so what should be my event handler(which in my case is ADF pipeline)?
Please suggest:
Azure Storage Event subscription is mandatory to fire Blob creation triggers? if yes then Event Handler option.
If it is not mandatory(as per my research only Event Grid has to be registered) what is causing my Event trigger to not fire?
Must be using a V2 Storage Account
Trigger name must only contain letters, numbers and the '-' character (this restriction will soon be removed)
Trigger makes the following properties available #triggerBody().folderPath and #triggerBody().fileName. To use these in your pipeline your must map them to pipeline paramaters and use them as such: #pipeline().parameters.paramaetername.
Have you followed above guidelines? If yes, maybe you could consider create a support ticket.

I created an Azure logic app for running my actions from my application.
so my requirement is to upload the blob to the shared folder from Azure blob.
for that my team is created azure data factory pipeline,
so from the logic app designer I am running the trigger when the blob is added or modified, I need to run the pipeline from the azure data factory,
while running the trigger, the trigger is fired successfully but it is running at the blob only it is not going to the second action.
can you please give me the guidance how should I resolve the issue.
Azure data-factory provides the option of azure blob trigger which will work automatically. When new blob gets added your pipeline will run.
Data Factory Event Trigger
In this case you don't need separate logic app for the triggering event.
I created an event subscription for BlobCreated event. I'm using Azure Functions with an EventGridTrigger to receive the events. Right now, events are firing every time a new blob is created. Is it possible to create an advanced filter in the event subscription so that the events are delivered only when a blob contains metadata?
No, this feature is not supported in the AEG Advanced filtering, see the event schemas for Azure Blob Storage as an Event Grid source here.
As you can see in this document, there is no blob's metadata in the event data object.
Is it possible to use some ready made construct in azure cloud environment to ingest the events (in json format) that are currently stored in azure blob storage and have it submit those events directly to azure event hub without writing any (however small) custom code? In other words, I would like to use configuration driven approach only.
Sure. You can try to use Azure Logic Apps to realize your needs without any code or just with some function expressions, please refer to the offical documents of Azure Logic Apps to know more details.
The logic flow is as the figure below.
You can refer to my sample below to make it works.
Here is my sample to receive an event from my EventHub and transfer to Azure Blob Storage to create a new blob for storing the event data.
Create an Azure Logic App instance on Azure portal, it should be easy for you.
Move to the tab Logic app designer to configure the logic flow.
Click Save and Run buttons. Then, use ServiceBusExplorer (downloaded from https://github.com/paolosalvatori/ServiceBusExplorer/releases) to send event message and check whether new blob created using AzureStorageExplorer. It works fine after a few minutes.
I need to move data received in my Service Bus Topic to a Storage Account inside Azure.
I believe Azure Function is one of the good ways to achieve this.
Please share suitable example if you have one.

Fire up an Azure Functions project, create a function with a Service Bus trigger binding (if you're in the portal or Visual Studio then it'll offer you a template) and add a storage output binding for blob, queue or table as appropriate. Then in the function code just copy the relevant data from your trigger parameter to your output parameter.
I need a way to trigger the Azure functions when an entity is added to the Azure Table storage. Is there a way to do this ? When I tried to add a new Azure function, I did not see any Azure Table storage trigger. I see there is Queue and Blob triggers available.
If there is no support for the Azure table storage trigger, then should I need to have a Http trigger and have the Azure Table storage as input binding ?
Thanks
There is no trigger binding for Table Storage.
Here's a detailed view on what is supported by the different bindings available today:
https://learn.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings#overview
If there is no support for the Azure table storage trigger, then should I need to have a Http trigger and have the Azure Table storage as input binding ?
Yes, this approach would work and would allow you to pass the table data as an input while relying on a separate trigger. Depending on the type of clients you are working with, and your requirements, using a queue trigger is also another good option.
#venki What the Fabio Cavalcante said to you is really true. Azure Function doesn't have a trigger option for Storage Table. But, whether your business needs store the data into the Storage Table and you as a Developer decide to use Azure Function into your architecture, you're able to configure you Function to use data that will come from Storage Table as a Input to your Function! This works really well.
But, There is another way to configure your Function to have "automagically" trigger, using Storage Queue (for small business) or Service Bus (for a business that needs a mechanism more robust)
