A school-bus depot is handed ridership files, delay logs, and weather extracts that use different date columns. Staff want to concatenate first and clean later. What is the right ingest order?
Select an answer to reveal the explanation.
Short Explanation
Ridership, delay logs, and weather extracts with different date columns. Ingest each source, align schemas, then combine. Blind concatenate is not prep, Triton is not a schema merge, and a kernel that ignores column names is not ingest.
Full Explanation
Preparing several datasets includes schema alignment before a union or join. A blind concatenate of ridership, delay, and weather files with mismatched date columns is not ingest. This remains Domain 4 data prep, not an experiment and not a serving merge. Align, then combine.
