Hi all, Just following up on this thread to see if anyone might have time to review the Azure Blob Storage Backup Repository PR: https://github.com/apache/solr/pull/3750 <https://github.com/apache/solr/pull/3750?utm_source=chatgpt.com>
I realize it’s a large diff (~70 files), but the actual implementation is focused on about 10 files (5 main code files and 5 test files); the rest are license header updates. Since this module mirrors the existing s3-repository design, I’d love feedback on structure, config parity, and test coverage to ensure it aligns with existing cloud repository modules. Happy to break it into smaller PRs or add more docs if that helps review. Thanks again for your time and guidance!
