Demo Data Post

Capabilities

• Loads any named pack from the DataHub registry (bootstrap, showcase-ecommerce, covid-bigquery)
• Loads custom packs from arbitrary HTTP(S) URLs via pack_url
• Time-shifts timestamps so ingested metadata appears current (set no_time_shift: false)
• SHA256 integrity verification for registry packs
• Local caching to avoid repeated downloads

Limitations

• Data packs are read-only collections of MCPs; they cannot be modified before loading.
• Time-shifting adjusts all temporal fields by a fixed offset — relative ordering is preserved but absolute times may not match real-world events.
• Custom URL packs (pack_url) bypass SHA256 verification unless the pack includes a checksum.

Troubleshooting

• "Pack not found": Verify the pack name with datahub datapack list. Pack names are case-sensitive.
• Trust errors: Community and custom packs require explicit opt-in via trust_community: true or trust_custom: true.
• Download failures: Check network connectivity to the pack URL. Use no_cache: true to force a fresh download if a cached file is corrupted.
