Unifying public and private data: Scale knowledge graphs with Data Commons on Spanner
Google announced the general availability of Data Commons on Spanner Graph and a preview of the new Data Commons Platform, which unifies public and private data into scalable knowledge graphs. The new architecture uses a native graph model with Spanner Graph and GQL to replace legacy cache-based systems.
Why it matters
This allows businesses to easily combine their internal data with vast public datasets, such as those from the World Bank or US Census Bureau, to gain deeper insights without complex data integration. This enables use cases like a retail company analyzing public economic trends against its own sales data to find new market opportunities.
The details
- Data Commons includes over 400 billion statistical observations from 100+ authoritative sources.
- The new system supports SDMX 3.0 for integration with third-party tools.
- Private instances let users control access while querying public and private data together.
