Which component of SAP HANA Indexserver facilitates client connections to the database?

The component of SAP HANA Indexserver that facilitates client connections to the database is the External Interfaces. This part serves as the point of interaction for external applications and clients accessing the database. It is responsible for managing incoming requests from various clients and orchestrating the communication between them and the database system.

The External Interfaces handle tasks such as interpreting SQL commands and ensuring that they are correctly routed to the appropriate internal components of SAP HANA for processing. By functioning in this capacity, the External Interfaces enable seamless connectivity and communication, allowing clients to perform operations on the database effectively.

The other components mentioned, while critical to the overall architecture and functionality of SAP HANA, do not specifically serve the purpose of establishing and managing client connections. The Data Provocation Layer focuses on data handling, while the SQL Execution Engine processes queries. The Communication Router is involved in directing messages within the system but does not directly handle client connections.
