Parallel Processing Using Partitions With Vertica UDx

You can add functionality to Vertica using UDx, but what if you need to process more data than can be efficiently processed in a single thread or a single node? Vertica can divide data into partitions defined with the OVER() clause and distribute computing across nodes. This partition processing is "shared-nothing" similar to the Map...

Extending Vertica with Python functions: Adding NumPy FFT as a UDx

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...

Using Java UDX in Vertica

Michael Flower authored this post. Introduction Vertica has a highly extensible UDx framework, which allows external user-defined functions, parsers and data loaders to be installed onto the Vertica server. This means that a routine written in C++, R, Java or Python can be run in-database as a Vertica SQL function. This blog is based on...

Introducing the Vertica ML-Python Library

This blog post was authored by Soniya Shah. One of the coolest things about working at Vertica is our amazing intern program, which often leads to full-time hires. Last year, the Vertica-ML-Python library, also known as vpython, was started as an internship project by Badr Ouali. A year later, he works for Vertica full time...

How to Code Vertica UDx

This blog post was authored by Ding-Qiang Liu. In analytic businesses supported by Vertica, complex processing logic is sometimes unavoidable. Using ANSI SQL might cause query strings to be much longer, and will slow the query with a huge volume data to query. If using Vertica SDKs, you can encapsulate that general computing logic in...
