Key Features

Automatic TEE Detection

The library automatically detects whether it's running in a secure TEE environment:

• Development/Local: Returns sample data for testing
• Secure TEE: Returns real sensitive data after attestation

No configuration needed - it just works with automatic environment awareness!

Column Filtering

Request only the columns you need:

from delong_datasets import download_dataset, DownloadOptions

opts = DownloadOptions(columns=["patient_id", "diagnosis"])
data = download_dataset("<dataset_id>", token, opts)

Streaming Large Datasets

Process datasets that don't fit in memory:

opts = DownloadOptions(stream=True)
dataset = download_dataset("<dataset_id>", token, opts)

for batch in dataset.iter(batch_size=1000):
    process(batch)

Multiple Export Formats

from delong_datasets import export_data

# Export to CSV, JSON, or Parquet
export_data(data, format="csv", path="/tmp/output.csv")
export_data(data, format="parquet", path="/tmp/output.parquet")
