Hi Praveen, We will add a "Getting Started" section in the README soon, but basically comet-spark-shell in the repo should provide a basic tool to build Comet and launch a Spark shell with it. Note that we haven't

This is very cool! Congrats on the amazing work Chao and the team! It's exciting to see this native engine trend within the community. Other than gluten, I ran into https://github.com/blaze-init/blaze as well (but haven't evaluated it in detail) On Wed, Feb 14, 2024 at 09:20 Chao Sun wrote: > >

This looks really cool :) Out of interest what are the differences in the approach between this and Glutten? On Tue, Feb 13, 2024 at 12:42 PM Chao Sun wrote: > Hi all, > > We are very happy to announce that Project Comet, a plugin to > accelerate Spark query execution via leveraging DataFusion

Introducing Comet, a plugin to accelerate Spark execution via DataFusion and Arrow

Hi all, We are very happy to announce that Project Comet, a plugin to accelerate Spark query execution via leveraging DataFusion and Arrow, has now been open sourced under the Apache Arrow umbrella. Please check the project repo https://github.com/apache/arrow-datafusion-comet for more details if
