I'm trying to start with the DataStream API, but have a missing module.
Any idea what's wrong ?
Version
Python 3.7.9
python -m pip install apache-flink
Code
from pyflink.common.serialization import SimpleStringEncoder
Error
ModuleNotFoundError: No module named pyflink.common.serialization
The DataStream API is not supported yet in PyFlink. This is planned for Flink 1.12, with the initial work described in FLIP-130.
Sorry if you were misled by the master version of the documentation. If you still want to try the Python DataStream API, you can build PyFlink from source.
