transaction logs asynchronously

 what is the purpose of the change feed ?

The purpose of the change feed is to provide transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account.

The change feed provides ordered, guaranteed, durable, immutable, read-only log of these changes. Client  applications can read these logs at any time, either in streaming or in batch mode.

The change feed enables you to build efficient and scalable solutions that process change events that occur in your Blob Storage account at a low cost.
