These changes are not in the upstream spec:

I've requested that encoding is added and AFAIK prediction_config types were already requested.

awesome 😊

+      );

+    // Workaround: Endpoint requires a filename that ends with .parquet


[q] Does it make sense to ask the service owners to ignore the filename and just look at the format?

I already asked.

+   * @param parquetData - Parquet file data as Blob. Can also be a File to forward the filename.


[nth] Maybe add a few words an what is in the file. I think prediction data and data schema.

Support Parquet input in RPT client

New Features

✨ Added support for Parquet file format in the RPT (Relational Prediction Transformation) client, enabling efficient binary tabular data predictions with typed columns.

Changes

RPT Client API Enhancements

packages/rpt/src/client.ts: Implemented predictParquet() method to handle Parquet file data (Blob or File) with configurable prediction options
packages/rpt/src/types.ts: Added PredictionOptionsParquet interface for Parquet-specific configuration options
packages/rpt/src/client/rpt/schema/body-predict-parquet.ts: Updated schema to properly type Parquet file input and prediction config
packages/rpt/src/client/rpt/rpt-api.ts: Enhanced API to handle multipart/form-data encoding for Parquet uploads
packages/rpt/src/spec/rpt.json: Updated OpenAPI specification to properly define Parquet content type and encoding

Core HTTP Client Improvements

packages/core/src/http-client.ts: Enhanced to preserve FormData objects without stringification, enabling proper multipart uploads
packages/core/src/http-client.test.ts: Added comprehensive tests for FormData handling and JSON stringification

AI API Client Updates

Generated clients were updated with improved parameter ordering and content-type headers:

packages/ai-api/src/client/AI_CORE_API/: Multiple API files updated with proper header and query parameter handling
packages/document-grounding/src/client/api/: Document grounding APIs updated
packages/prompt-registry/src/client/prompt-registry/: Prompt registry APIs updated
packages/foundation-models/src/azure-openai/client/: Audio transcription/translation schemas updated to use Blob type

Sample Code & Documentation

sample-code/src/rpt.ts: Added predictParquetFile() and predictParquetBlob() examples
sample-code/src/product_data.parquet: Added sample Parquet data file for testing
sample-code/resources/generate_parquet.py: Python script to generate sample Parquet data
sample-code/src/server.ts: Added /rpt/predict-parquet endpoint

Testing

tests/e2e-tests/src/rpt.test.ts: Comprehensive e2e tests for Parquet predictions
All tests verify prediction results with proper data type handling

Build Configuration

package.json: Updated to use canary SAP Cloud SDK versions for multipart support
sample-code/package.json: Updated compile script to copy Parquet file to dist
pnpm-lock.yaml: Updated dependencies to use canary versions

File API Changes

packages/ai-api/src/client/AI_CORE_API/file-api.ts: Updated fileDownload() return type to Blob for proper binary handling
