The new vector data type REAL_VECTOR was introduced with HANA Cloud Database QRC 1/2024. Details about the new type are available at the SAP HANA Database Vector Engine Guide.

HANA's JDBC driver natively supports that type starting with version 2.21.5.

A new value handler should be introduced so that vectors are displayed like arrays. Furthermore, the column type modifiers should be adapted to display vector dimension constraints.

I'd like to implement the support of the new type myself.

Is this not present in on premise Hana?

@mahanteshimath
No, the Vector Engine is a HANA Cloud only feature. There are currently no plans to also add it to on-premise HANA.
