Thanks for opening a pull request!

If this is not a minor PR. Could you open an issue for this pull request on JIRA? https://issues.apache.org/jira/browse/ARROW

Opening JIRAs ahead of time contributes to the Openness of the Apache Arrow project.

Then could you also rename pull request title in the following format?

or

I rewrote master to remove the history of the other languages (and 50MB of history). This means this PR will need to be "rebased" against the current master.

The best way I found to do this was to find the relevant commits (via git log) and then cherry-pick them one at a time. For example (change COMMIT-SHA to whatever the commit actually is):

git reset --hard apache/master
git cherry-pick COMMIT-SHA
git push -f your_rep
