Phil Price commented on ARROW-8394:
-----------------------------------
This also happens with `0.17.0` from what I can tell there are two things which
I would consider adoption blockers:
# `apache-arrow` compiles with [email protected], but [email protected]+ has
stricter type-checks, and cannot consume the output. A couple of cases I've
found that are invalid:
## Extension of static `new()` methods with different typed parameter order
(column<T> derived from chunked<T> but changes the signature of `new` to takes
`string | Field` as the first param over `Data`
## Not passing template types to fields (e.g. `foo: Schema` to `foo:
Schema<T>`)
# Attempting to upgrade `apache-arrow` to [email protected] (or 3.9-beta) falls
afoul of a typescript compiler bug
([https://github.com/microsoft/TypeScript/issues/35186]); from my
understanding, the compiler is on an error path anyway but bails when trying to
print error detail. This makes the upgrade difficult as it's a case of
whack-a-mole.
