Blob storage event for metadata changes

[SeanFeldman]

Usecase scenario

Azure Event Grid events for Blob storage has no event notifying about metadata changes. Microsoft.Storage.BlobCreated event doesn't carry those metadata changes either. In the scenarios when a blob's metadata is modified I'd like to receive an event.

Thanks @xyh1!

Is there a target date for this?

[m1dst]

I heard this might be available by Ignite 2020. Did the target get met?

[xyh1]

I don't recall communicating Ignite 2020 as the target date. But it is not available yet.

I believe it is still being worked on but cannot comment on dates as I no longer work on the Storage team.

However if you look at the related feature for Blob Change feed, you'll notice that additional events (SetBlobProperties/SetBlobMetadata/SetBlobTier) are all captured and logged. These events + more would make their way to event grid.

Any news on this topic?

We have a use case where we are appending to an append blob and marking it with a "Blob index tag" to specify when we are done appending to the blob. Additionally, we do seal the append blob and this would also be a great event to notify on.

Would like an update on this too, been 2 years and I believe its a common event to subscribe to when having storage systems.

@xyh1, any updates on this one?

Unfortunately I can't speak to this. I've not been a Microsoft employee for 3 years now 😉

Last I recall on this is that I asked for it to be included in change feed: https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-change-feed?tabs=azure-portal#event-record-schemas However it doesn't look like it was populated to event grid.

I would suggest opening up a support case request about it or reaching out to one of the Azure Storage PMs
