The .hdiconfig file is a container-level configuration file for the SAP HANA Deployment Infrastructure (HDI). Its purpose is to specify which HDI plug-ins are active for a given HDI container. This file contains a JSON-formatted list that maps specific file extensions (e.g., .hdbtable, .hdbprocedure) to the corresponding plug-in responsible for processing and deploying those artifact types. By editing this file, developers can enable or disable the processing of certain database object types within their project.

A. Deployment space is a runtime target specified during the deployment command (e.g., using the Cloud Foundry CLI), not within the .hdiconfig file.

B. Access to external schemas is configured using user-provided services (UPS) and grant files (e.g., .hdbgrants), not the .hdiconfig file.

D. Namespace rules, which allow for object name prefixing and aliasing, are defined in a separate configuration file named .hdinamespace.

1. SAP HANA Developer Guide for SAP HANA XS Advanced Model: In the section "The SAP HDI Container Configuration File (.hdiconfig)"

it states

"The plug-ins to use for the deployment to an HDI container are defined in a configuration file (.hdiconfig)... The .hdiconfig file contains a JSON-formatted list of plug-ins that map a file extension to the plug-in that is responsible for handling files with the specified extension." (SAP Help Portal

SAP HANA Platform 2.0 SPS 07).

2. SAP HANA Deployment Infrastructure (HDI) Reference: The section "Container-Level Configuration (.hdiconfig)" explains

"The .hdiconfig file is a JSON file that lists the file suffixes and corresponding HDI plug-ins that are recognized by the HDI deployer... By default

an HDI container is configured to use all available HDI plug-ins. However

you can use the .hdiconfig file to specify a list of plug-ins to use for deployment." (SAP Help Portal
