The CAP Java feature that wires a Maven application to PostgreSQL as its datasource beside SAP HANA, with limitations capire lists: schema evolution first, and no multitenancy or extensibility yet.

For CAP it is the production database when the answer is not HANA, reached through an adapter that translates CDS queries into its SQL. as a datasource for a CAP Java application built on com.sap.cds:cds-services-bomcom.sap.cds:cds-services-bomThe Maven bill of materials for CAP Java, pinning every com.sap.cds module in a release, from the API and core runtime to the Spring Boot starters and the CQN engine, to the same version.sap official, cap. Added as a runtime-scoped Maven dependency, it auto-configures the default Persistence Service from a bound PostgreSQL instance and lets cds deploy --to postgres --dry generate the schema.sql Spring runs on startup. PostgreSQL is supported in addition to SAP HANASAP HANASAP’s relational database platform, which stores application data and executes SQL and SQLScript in the database, available on-premise and as the managed service SAP HANA Cloud.sap official, btp; capire lists limitations in comparison, schema evolution first among them, and multitenancy and extensibility are not yet supported on it. On SAP BTP, Cloud Foundry only the community java_buildpack can consume a PostgreSQL service from a CAP Java application, and the buildpack's own datasource initialization has to be disabled so CAP Java creates the datasource instead. The Node.js counterpart is @cap-js/postgres@cap-js/postgresThe PostgreSQL database service — the production option for running CAP off HANA, sharing the base service with the other three.sap official, cap.

- § 1 License. Productive customer applications are limited to SAP BTP or another SAP-licensed platform, and mass extraction to a non-SAP product is restricted except where solely required for SAP interoperability.
The connector itself does not decide the licence boundary. Section 1 makes the destination and purpose of extraction relevant, including the scoped exception for interoperability with an SAP product.
