README

Output mapping library for Keboola Runner and Workspaces. Processes component outputs and uploads them to Keboola Storage API.

Tables:

• Local staging: Uploads tables as gzipped CSV files to Storage API
  • Slicing: Large CSV files are automatically split into multiple compressed chunks for parallel upload (via external slicer binary)
    • Requires: output-mapping-slice feature flag, default CSV format (, delimiter, " enclosure), no custom columns mapping
    • Sliced files must have columns or schema specified in configuration
• Workspace staging (Snowflake/BigQuery): Loads tables directly from workspace database objects (no file upload, no slicing)

Files:

• Uploads files as-is to Storage API File Storage (works with all staging types)
