There seems to be some consensus growing around the Acero name. There is not much code right now that refers to "the engine" as a standalone concept but we do have documentation that describes a "streaming execution engine". I've created a PR[1] to update the documentation we do have to use the name Acero.
For those that wish to fine-tune the messaging of Acero it would probably be best to direct improvements to the PR (or open additional PRs). This ML thread can then be left for discussion of alternative names or concerns around the naming itself. I, for one, am more eager to get this naming dilemma behind us and worry about functionality :) [1] https://github.com/apache/arrow/pull/13207 On Fri, May 20, 2022 at 7:06 AM Andy Grove <andygrov...@gmail.com> wrote: > > Arrow Compute/C++ Engine for Relational Operations? > > On Fri, May 20, 2022 at 9:31 AM Aldrin <akmon...@ucsc.edu.invalid> wrote: > > > Perhaps: > > "Acero (aˈsɛɾo): *A* *c*ompute *e*ngine for Ar*ro*w" - Most similar to > > Will's 3rd option, but enforces that it purposefully sounds like "ACE > > Arrow" or something to that effect.
