------------------------------------------
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.
