File Content Settings Manager

Build a utility that manages HTTP headers and content settings for files stored in Azure Data Lake Storage Gen2.

Requirements

Create a Python module that provides functionality to configure and retrieve HTTP headers for files in Azure Data Lake Storage. The module should handle:

1. Setting Content Properties: Configure HTTP headers including content type, content encoding, content language, content disposition, and cache control for files
2. Retrieving Content Properties: Fetch and display the current content settings for a file
3. Bulk Updates: Update content settings for multiple files based on file extension patterns

Implementation Details

Your implementation should include:

• A function set_file_content_settings(file_client, content_type, content_encoding, content_language, content_disposition, cache_control) that configures all HTTP headers for a file
• A function get_file_content_settings(file_client) that retrieves and returns the current content settings
• A function update_files_by_extension(file_system_client, extension, content_type, cache_control) that updates content type and cache control for all files with a given extension

Test Cases

• Setting content type to "application/json", encoding to "gzip", language to "en-US", disposition to "attachment; filename=data.json", and cache control to "max-age=3600" on a file successfully updates all properties @test
• Retrieving content settings returns the configured values for content type, encoding, language, disposition, and cache control @test
• Updating all .csv files to have content type "text/csv" and cache control "no-cache" correctly updates only files with .csv extension @test
