Presto on ARM – Chunxu Tang & Jiaming Mai, Alluxio

Presto on ARM – Chunxu Tang & Jiaming Mai, Alluxio

Traditionally, the deployment of Presto has been limited to Intel processors with the x86 architecture. However, with the growing popularity of ARM architecture, Chunxu and Jiaming have extended the Presto ecosystem to ARM and conducted a series of benchmark experiments. Their objective is to evaluate the performance of Presto on ARM architecture and identify key insights from the experiments. In this presentation, Chunxu and Jiaming will share the results of their performance evaluation and discuss some of the most significant findings from their research.

Building Large-scale Query Operators and Window Functions for Prestissimo using Velox – Aditi Pandit

In this talk, Aditi Pandit, Principal Software Engineer at Ahana and Presto/Velox contributor, will throw the covers back on some of the most interesting portions of working in Prestissimo and Velox. The talk will be based on the experience of implementing the windowing functions in Velox. It will cover the nitty gritty on the vectorized operator, memory management and spilling. This talk is perfect for anyone who is using Presto in production and wants to understand more about the internals, or someone who is new to Presto and is looking for a deep technical understanding of the architecture.
