Under the hood of the Delta Sharing protocol

How a Delta Sharing server, dsserv, implements the open-source Delta Sharing protocol for zero-copy sharing: Delta tables ingested, governed and streamed live from local S3-compatible storage into cloud consumers such as DatabricksDatabricksoutside the atlasA unified data and AI platform. sap-bdc-mcp-server creates the Delta shares it registers with SAP Business Data Cloud in a Databricks workspace.. Neither the server nor the protocol is an atlas entry; the edges are to data federationData federationcapabilityReading data that lives in another system as if it were local — by federating the query, by copying the rows, or by caching what was read. Three different answers to one question, and the choice is about how stale you can afford to be.SAP and community, narrow by design, the concern zero-copy sharing answers, and to object storageObject storagecapabilityStoring application files as objects in a bucket or container backed by a cloud storage service. Connecting a file to a business record is the separate Attachments concern.SAP only, where the tables sit, and the abstract names no SAP product.
