Chesnay Schepler commented on FLINK-16026:
------------------------------------------
{{It may be not a good idea to limit the versions of the transitive
dependencies to a different version declared by the direct dependency:}}
I disagree.
{{We should trust the direct dependency, e.g. if apache-beam declares that it
support avro-python3<2, we should trust that it does support all versions of
avro-python3 which are less than 2.}}
Not a single project can guarantee that it supports any future version of
another library, as they have no control over it.
For all we now, the next version of avro-python3 breaks the entire API.
This is just a broken concept, and we see the fallout of this repeatedly in
this project and in the JavaScript ecosystem.
{{We have to upgrade the versions of the transitive dependencies periodically
if new packages have been released}}
Correct, we have to ensure that when we bump a dependency everything still
works. I don't consider this a bad thing.
{{For released package of PyFlink, there is no way to upgrade the versions of
the transitive dependencies any more}}
This is not a problem imo, but a benefit. It means the release is stable and
will not magically stop working 2 years down the road.
