You are running a Dataflow pipeline in production. The input data for this pipeline is occasionally inconsistent. Separately from processing the valid data, you want to efficiently capture the erroneous input data for analysis.
A
Re-read the input data and create separate outputs for valid and erroneous data.
B
Read the data once, and split it into two pipelines, one to output valid data and another to output erroneous data.
C
Check for the erroneous data in the logs.
D
Create a side output for the erroneous data.
