[jira] [Created] (OAK-8580) Stack trace logging for all binary downloading of cloud blob stores

Alexander Klimetschek created OAK-8580:
------------------------------------------

             Summary: Stack trace logging for all binary downloading of cloud blob stores
                 Key: OAK-8580
                 URL: https://issues.apache.org/jira/browse/OAK-8580
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: blob-cloud, blob-cloud-azure
    Affects Versions: 1.8.16, 1.16.0
            Reporter: Alexander Klimetschek
            Assignee: Matt Ryan


We want to be able to trace application code that invokes Binary.getInputStream() when a cloud blob store is present.

The Azure blob store has one place where it supports trace logging [here|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-blob-cloud-azure/src/main/java/org/apache/jackrabbit/oak/blob/cloud/azure/blobstorage/AzureBlobStoreBackend.java#L1202-L1207], but this misses another place blobs are fetched in [read()|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-blob-cloud-azure/src/main/java/org/apache/jackrabbit/oak/blob/cloud/azure/blobstorage/AzureBlobStoreBackend.java#L218].

Furthermore, it would be nice to have a separate logger for that in order to create a log file that _only_ includes these stack traces, and no other debug logs of the AzureBackend class.

And same for the S3 BlobStore implementation.
