This option provides a versatile, high performance C++ Application Programming Interface (API) that allows users to extend the analytical capabilities of SAP Sybase IQ by plugging in externally built C++ functions. These external C++ functions operate in proximity to the data stored in SAP Sybase IQ and are often executed in a highly parallelized fashion, thereby providing high efficiencies in performance, usability, and total cost of ownership.
Users may deploy a wide array of SAP Sybase certified external function libraries from ISV partners inside SAP Sybase IQ, in any configuration. In addition, users may also deploy custom built external functions inside SAP Sybase IQ, but these can be deployed only in the reader nodes in a multiplex configuration.
