Guided Lab: Batch Ingestion and Transformation in Data Engineering Fundamentals
Data Engineering Fundamentals — Batch Ingestion and Transformation lab: Build a small batch pipeline that reads a source file, validates schema, transforms rows, writes output, and can be rerun without duplication.
Outcome summary
Know what success looks like before you begin
Save verification evidence: the relevant output, test, log, query result, or rendered state for Batch Ingestion and Transformation.
- I completed the module-specific practice task.

Lab brief
Know the problem and the evidence you need
Build a small batch pipeline that reads a source file, validates schema, transforms rows, writes output, and can be rerun without duplication.
a working batch ingestion and transformation example with an explicit success and failure check
Complete the task, verify the relevant output, test, log, query result, or rendered state for Batch Ingestion and Transformation, then diagnose one failure that is specific to Batch Ingestion and Transformation.
Move data through a pipeline with explicit schemas, idempotent processing, quality checks, lineage/observability, and recoverable orchestration.
Safety and setup
Prepare before changing anything
Have this ready
- Open a small local project or disposable lab environment.
- Confirm the runtime, toolchain, or service needed for the module.
- Prepare one valid input and one invalid or boundary input.
Field checks
0 of 5 checks completeRun the lab
Complete one check at a time. Record the evidence before moving on.
Interpret results
Match the evidence to the next action
If you seeNext action
The expected result appears and the boundary case behaves correctly
Save the result and continue to the module checkpoint.
The normal case works but the failure or boundary case does not
Return to the diagnostic step and inspect the module-specific state or output before changing more code.
The result changes between runs
Compare the relevant input, dependency, configuration, data, state, or runtime version for this module.
Choose the next action
Complete the lab when you can reproduce the working result, explain the important module decision, and recover from the tested failure.
