SAP® BDC Connect for Snowflake Zerocopy Connector — Security and Privileges¶

This topic describes the privileges required to create and manage a Zerocopy Connector and the catalog-linked databases created from it.

Access Control Requirements¶

A role used to execute this operation must have the following privileges at a minimum:

Privilege	Object	Notes
`CREATE ZEROCOPY CONNECTOR`	Schema	Required to create a Zerocopy Connector. By default, the schema owner has this privilege.
`OPERATE`	Zerocopy Connector	Required to connect or disconnect (`ALTER ... CONNECT` / `ALTER ... DISCONNECT`) and to publish a data product (`SYSTEM$SAP_PUBLISH_DATA_PRODUCT`).
`USAGE`	Zerocopy Connector	Required to create a catalog-linked database from the connector (also requires `CREATE DATABASE` on the account) and to add or remove a share from the connector (also requires `OWNERSHIP` on the share).
`MODIFY`	Zerocopy Connector	Required to set or unset properties (comment, share_back, etc.).
`MONITOR`	Zerocopy Connector	Any privilege on the connector (e.g. `MONITOR`) is sufficient to describe the connector, show connectors, or list shares.
`OWNERSHIP`	Zerocopy Connector	Required to rename or drop the connector.
`CREATE DATABASE`	Account	Required to create a catalog-linked database from a Zerocopy Connector (also requires `USAGE` on the connector).

For instructions on creating a custom role with a specified set of privileges, see Creating custom roles.

Connector States¶

A Zerocopy Connector transitions through the following states. Understanding the state is important because some operations are only permitted in specific states.

State	Description
`NEW`	Initial state after the connector is created. No connection has been attempted yet.
`CONNECTING`	A connection attempt is in progress. The connector enters this state immediately after `ALTER ... CONNECT` is issued.
`CONNECTED`	The connection is established. Catalog-linked databases can only be created when the connector is in this state. Sharing data between Snowflake and SAP® BDC is only allowed when the connector is in this state.
`CONNECT_ERROR`	The connection attempt failed. The error message is persisted on the connector. You can retry the connection from this state.
`DISCONNECTING`	A disconnection is in progress. The connector enters this state immediately after `ALTER ... DISCONNECT` is issued.
`DISCONNECTED`	The connection has been dropped. You can reconnect from this state.
`DISCONNECT_ERROR`	The disconnection attempt failed. The error message is persisted on the connector.
`DELETED`	The connector has been dropped. This state is permanent — Zerocopy Connectors do not support `UNDROP`.

State Transition Rules¶

ALTER ... CONNECT is permitted when the connector is in NEW, CONNECT_ERROR, or DISCONNECTED state.
ALTER ... DISCONNECT is permitted when the connector is in CONNECTED or DISCONNECT_ERROR state.
Share-back must be disabled before disconnecting.
All catalog-linked databases created from the connector must be dropped before disconnecting.
DROP ZEROCOPY CONNECTOR is permitted when the connector is in NEW, CONNECT_ERROR, DISCONNECT_ERROR, or DISCONNECTED state.
Catalog-linked databases do not support UNDROP.
