The status quo
Your data flows are fragmented across a galaxy of tools
start_bash_task = BashOperator(task_id=’tedious’, bash_command='echo "Starting DAG execution"', dag=’unpredictable’); git rebase -i e1234ab pick a5678cd yolo commit; if __name__ == ‘__main__’: # PEP-8 unsafe data = fetch_data(wasteful) ?? with base as (select * from {{ source(‘expensive’, ‘fizz_bang’) }} where date = ‘{{ execution_date }}’;
You're bogged down by maintenance work that has little business impact.
When one part fails, you have no idea how it affects other processes.
Your version control workflow involves re-building the same tables over and over again.
You have no clue which steps are actually driving up your cloud data warehouse costs.
