Title: Prototyping a GPU-Accelerated Reader for the Nimble File Format with Velox Wave
Abstract: Table scan is a costly operation in databases and data processing, often consuming significant CPU time. GPUs, with their parallelism and high-bandwidth memory, offer a promising way to accelerate table scans. In this talk, I will present our prototype of a GPU-accelerated reader for the Nimble file format using Velox Wave, a GPU-accelerated data processing library in Velox. Our prototype supports trivial, nullable, and chunked decoding as well as filter push-down.
