I don't think we have the maintainer bandwidth to do anything else right now -- it's enough work to get just the single main repo release out. If the Rust community grows and there are PMC members working on Rust who want to manage independent releases, they are free to do that. > Besides critical bug/security fixes, at some point we may want to claim > that some module has reached a stable version and hence 1.X.X while others > should still stay at 0.X.X. I would guess we are quite a ways away from this goal, we're talking sometime 2020 at earliest. I'm concerned that adding a bunch of maintainer overhead right now will make things move more slowly without clear benefit. > > On the Rust side, we should strive to keep the arrow crate version the same > as the main release version, but perhaps we can allow differences in other > "supporting" crates? Unless the supporting crates have decoupled Apache releases I think using different versions is only going to be confusing. Having separate Apache releases is only really practical if there are willing release managers on the PMC. > > On Sun, Jan 6, 2019 at 3:48 AM Uwe L.
