Kenneth Knowles updated BEAM-2600:
----------------------------------
Description:
In order to build a pipeline that invokes a Python UDF, we need to be able to
construct something like this:
{code}
SdkFunctionSpec {
environment = <python SDK harness>,
spec = {
urn = <python SDK pickled DoFn>,
data = <pickled DoFn>
}
}
{code}
I could be out of date, but based on a couple of conversations I do not know
that there exists anything we can put for "<python SDK harness>" today. For
prototyping, it could be just a symbol that runners have to know. But
eventually it should be something that runners can instantiate without knowing
anything about the SDK that put it there. I imagine it may encompass "custom
containers" eventually, though that doesn't block anything immediately.
