- Sharing uncooked tables can expose delicate data unintended for the recipient.
- Sharing mixture knowledge requires additional processing, thereby slowing knowledge supply.
Finally, balancing freshness, efficiency, safety, and ease is tough, and older architectures hardly ever get it proper.
Utilizing the open‑supply Delta Sharing protocol, MVs and STs might be shared throughout clouds, areas, and platforms to a variety of recipients.
Materialized Views (MVs) ship precomputed, aggregated question outcomes, permitting groups to share solely the required insights as an alternative of full uncooked datasets—enhancing safety and relevance. That is particularly invaluable when shoppers want filtered or summarized outcomes however not detailed supply knowledge, akin to sharing every day business‑stage efficiency summaries from monetary transactions with a hedge fund buyer.
