Upload multiple mainframe files

Uploads multiple mainframe files to a specified directory path within the pipeline using batch upload API.

Process Overview:

1. Request Validation - Validates path and file list
2. Resolution Strategy - Applies specified conflict resolution (REPLACE_ALL, IGNORE_ALL, PARTIAL)
3. Batch Upload - Uploads all files in a single operation
4. Result Aggregation - Returns success/failure results for all files

Conflict Resolution Strategies:

• REPLACE_ALL - Replace all existing files with conflicting names
• IGNORE_ALL - Skip all files with conflicting names, keep originals
• PARTIAL - Replace only files specified in replaceFiles list, others are ignored

Archive Expansion:

• When uploading a single ZIP file with expandArchive=true, the archive will be extracted
• Individual files will be created from the archive contents
• For multiple files, expandArchive is ignored

Key Features:

• Batch upload support for multiple files
• ZIP archive expansion for single file uploads
• Automatic path handling (uses path as prefix for all files)
• Lists created, conflicted, updated, and ignored files

Path Handling:

• Files are uploaded to the specified directory path
• Directory path (e.g., '/path/to') is used as prefix for all uploaded files

Use Cases:

• Bulk import of configuration files
• Upload multiple scripts at once
• Initial pipeline setup with multiple files

Required Permissions: replication-pipeline::create when permission harmonization is enabled; otherwise, replication-pipeline::manage.
