Hello there!

Today we'll explore the usage of WebAssembly to streamline User Defined Functions. We're going to do that with the help of our guest ⁠Andrea Fonti⁠ and our dear host ⁠Antonio Murgia⁠. User-defined functions (UDFs) have long been a powerful tool for extending database and query engine capabilities. From traditional relational databases to modern big data platforms like Hive and Spark, UDFs enable developers to introduce custom logic tailored to their specific needs. However, the existing methods of implementing UDFs often come with significant constraints: rigid language requirements, security concerns, and performance bottlenecks. WebAssembly (Wasm) is a technology that promises a more flexible, secure, and efficient approach to UDF development.
