Hi All, Ursabot works pretty well so far, and the CI feedback times have become even better* after enabling the docker volume caches, the development and maintenance of it is still not available for the whole Arrow community.
While it wasn't straightforward I've managed to separate to source code required to configure the Arrow builders into a separate directory, which eventually can be donated to Arrow. The README is under construction, but the code is available here [1]. Until this codebase is not governed by the Arrow community, decommissioning slow travis builds is not possible, so the overall CI times required to merge a PR will remain high. Regards, Krisztian * C++ builder times have dropped from ~6-7 minutes to ~3-4 minutes * Python builder times have dropped from ~7-8 minutes to ~3-5 minutes * ARM C++ builder time have dropped from ~19-20 minutes to ~9-12 minutes [1]: https://github.com/ursa-labs/ursabot/tree/a46c6aa7b714346b3e4bb7921decb4d4d2f5ed70/projects/arrow
