Hello everyone,

Can anyone explain me about the structure and implementation of DoFn Lifecycle.
The application and implementation in the pipeline, for example, the ParDo, etc.

Thanks
Siddharth

Subject: Request for Guidance

Hello everyone,


  1.
I’ am Siddharth Salian an undergraduate student currently pursuing BTech, last 
year I had tried for GSoC 2025 for Apache Beam. Since it was too early, I 
couldn’t proceed ahead.
  2.
So I’ am a beginner, currently going through the documentation of Apache beam, 
have gone through pipeline structuring, etc.
  3.
I shall be going with Java SDK, but Iam comfortable in Python language too.
  4.
I went through the good first issues in GitHub, post-that went through the 
general recent issues, but Iam not able to understand the codebase and the 
flow. So I don’t know where to start exactly.
  5.
Therefore, if anyone could give me guidance that would be grateful.

Thanks
Siddharth
