BigQuery is Google Cloud's fully managed, serverless data warehouse, popular for its scalability and tight integration with the rest of the Google Cloud ecosystem. Like other managed warehouses, it's closed source and billing is tied to the data you scan and store, which can make costs harder to predict at scale.
If your analytics needs are actually centered on AI-native, multimodal data rather than classic structured querying, Activeloop is an open-source option worth evaluating.
