Hi all,
we're using pyflink for most of our flink work and are sometimes into a
java process function.
Our new java process function takes an argument in in the constructor which
is a Row containing default values. I've declared my Row in pyflink like
this:
default_row = Row(ep_uuid="",
unit_uuid=None,
unit_longitude=None,
unit_latitude=None,
unit_state=None,
unit_country=None,
pf_uuid=None,
pf_name=None)
row_type_information = RowTypeInfo([Types.STRING(), # ep_uuid
Types.STRING(), # unit_uuid
Types.DOUBLE(), # unit_longitude
Types.DOUBLE(), # unit_latitude
Types.STRING(), # unit_state
Types.STRING(), # unit_country
Types.STRING(), # pf_uuid
Types.STRING() # pf_name
])
I'm now trying to get a handle to a java row object in the jvm so I can
pass that into the process function's constructor.
endpoint_info_enriched_stream =
DataStream(ds._j_data_stream.connect(endpoint_info_stream._j_data_stream).process(
jvm.org.switchdin.operators.TableEnrich(j_obj)))
I've tried a few approaches, but I really can't figure out how to do this,
I'm not sure what I need on each side for this, a coder, serializer,
pickler?
