Use arrow wheels to include arrow as a dependency in Ray #3162
Description
At the moment we are compiling a fixed version of arrow as part of Ray (see
). To- improve build times,
- share more release infrastructure with arrow and
- make it easier for companies who package library dependencies separately to deploy Ray,
it makes sense to include arrow into Ray via pre-built packages. Because both Ray and arrow are fast moving, this will probably need nightly arrow releases (see also https://github.com/kszucs/arrow/blob/420886bea341af43743bf7c822aeec768abd9ae7/dev/tasks/nightlies.sample.yml).
