How to make a generic Protobuf Parser DoFn in python beam?

QUESTION

How to make a generic Protobuf Parser DoFn in python beam?

Asked 2019-Apr-27 at 03:36

Context
I'm working with a streaming pipeline which has a protobuf data source in pubsub. I wish to parse this protobuf into a python dict because the data sink requires the input to be a collection of dicts. I had developed a Protobuf Parser successfully by initializing the protobuf message in process function of DoFn.

Why a Generic Protobuf Parser is Needed

However, I wanted to know, is it possible to make a generic ProtobufParser DoFn on Beam? A generic DoFn is useful from the engineering perspective to avoid re-implementing existing functions and enabling code reuse. In Java, I know that we're able to use generics hence implementing this generic ProtobufParser in Java is relatively easy. Since Python functions are first-class objects, I was thinking whether it's possible to pass a Protobuf schema class (not the message instance object) into a DoFn. I tried to do this, however I kept failing.

Successful Parser with Caveat: not Generalizable

Below is my current successful protobuf parser. The protobuf message is initialized inside process function.

I'm currently new to using Apache Beam in Python with Dataflow runner. I'm interested in creating a batch pipeline that publishes to Google Cloud PubSub, I had tinkered with Beam Python APIs and found a solution. However, during my explorations, I encountered some interesting problems which made me curious.

Currently, my successful beam pipeline for publishing data in batch manner from GCS looks like this:

PublisherClient can not be pickled correctly. More on pickling here. Initializing the PublisherClient in the process method avoids the pickling of PublisherClient.

If the intent is to reuse the PublisherClient, I would recommend initializing PublisherClient in the process method and storing it in self using following code.

Scaling Geometry Path based on actual height and width with of a usercontrol is very slow

Asked 2017-Nov-18 at 06:35

I have an application where I need to perform a fairly expensive calculation based on the actual width and height of a control. I have bound ActualWidth and ActualHeight of this control to properties in my code. I find that Actualheight is being changed in small steps. I assume this is because of the Layout Engine.
