> [C++] Use bcp to make a slim boost for bundled build
> ----------------------------------------------------

> Key: ARROW-8222
> URL: https://issues.apache.org/jira/browse/ARROW-8222
> Project: Apache Arrow
> Issue Type: Improvement

> We don't use much of Boost (just system, filesystem, and regex), but when we
> do a bundled build, we still download and extract all of boost. The tarball
> itself is 113mb, expanded is over 700mb. This can be slow, and it requires a
> lot of free disk space that we don't really need.
> [bcp|https://www.boost.org/doc/libs/1_72_0/tools/bcp/doc/html/index.html] is
> a boost tool that lets you extract a subset of boost, resolving any of its
> necessary dependencies across boost. The savings for us could be huge:
> {code}
> mkdir test
> ./bcp system.hpp filesystem.hpp regex.hpp test
> tar -czf test.tar.gz test/
> {code}
> The resulting tarball is 885K (kilobytes!).
> {{bcp}} also lets you re-namespace, so this would (IIUC) solve ARROW-4286 as
> well.
> We would need a place to host this tarball, and we would have to updated it
> whenever we (1) bump the boost version or (2) add a new boost library
> dependency. This patch would of course include a script that would generate
> the tarball. Given the small size, we could also consider just vendoring it.
