  • Manage object metadata: Configures HTTP request behaviors such as caching and forced download by setting standard HTTP properties, and employs custom metadata for additional file identification and attributes.

Search Queries

  • Query objects: Executes SQL queries directly within OSS to analyze CSV or JSON files, eliminating the need to download them for analysis.

  • Search objects: Rapidly locates files using the file name prefix, particularly effective in buckets containing many files.
