[DISCUSS] Deprecate previous Python APIs
Hi all!
I would suggest to deprecating the existing python APIs for DataSet and
DataStream API with the 1.9 release.
Background is that there is a new Python API under development.
The new Python API is initially against the Table API. Flink 1.9 will
support Table API programs without UDFs, 1.10 is planned to support UDFs.
Future versions would support also the DataStream API.
In the long term, Flink should have one Python API for DataStream and Table
APIs. We should not maintain multiple different implementations and confuse
users that way.
Given that the existing Python APIs are a bit limited and not under active
development, I would suggest to deprecate them in favor of the new API.
Best,
Stephan

Okay, so we seem to have consensus for at least deprecating them, with a
suggestion to even directly remove them.
A previous survey also brought no users of that python API to light [1]
I am inclined to go with removing.
Typically, deprecation is the way to go, but we could make an exception and
expedite things here.

features they support, and haven't been under active development for
several releases.
Existing users (if there even are any) could continue to use older
version against newer releases. It's is slightly more involved than for
say, flink-ml, as you also have to copy the start-scripts (or figure out
how to use the jars yourself), but it is still feasible and can be

Re: [DISCUSS] Deprecate previous Python APIs
Posted by jincheng sun <su...@gmail.com>.
big +1 for the proposal.
We will soon complete all the Python API functional development of the 1.9
release, the development of UDFs will be carried out. After the support of
UDFs is completed, it will be very natural to support Datastream API.
If all of us agree with this proposal, I believe that for the 1.10 release,
it is possible to complete support both UDFs and DataStream API. And we
will do our best to make the 1.10 release that contains the Python
DataStream API support.
So, great thanks to @Stephan for this proposal!
Best,
Jincheng

We will soon complete all the Python API functional development of the 1.9
release, the development of UDFs will be carried out. After the support of
UDFs is completed, it will be very natural to support Datastream API.
If all of us agree with this proposal, I believe that for the 1.10 release,

will do our best to make the 1.10 release that contains the Python
