Extending Vertica with Python functions: Adding NumPy FFT as a UDx
Bryan Herger, Vertica Big Data Solution Architect at Micro Focus
October 14, 2019
User-Defined Transform Function (UDTF) support for Python UDx were added back in Vertica 9.1, allowing you to add a much greater range of existing libraries and functions to Vertica. In this example, I'll add Fast Fourier Transform (FFT) from the NumPy package. FFT is a way to transform time-domain data into frequency-domain data. My test...
