Deploying DAG to Managed Airflow(AWS), with GitHub Action

Usually, data pipeline requires complex workflow. Generated data should be sent to various endpoints, and needs to be manufactured by status while moving on. For example, if there’s a log file stored in S3, the pipeline may need to Send this to ELK, for monitoring purpose every 10 minute Format to filter useless columns, and send to BigQuery for researching insights, every hour.

It is usually being used by data scientists, or business developer who needs to get insights from big data(probably stored inside S3, or else).

Making authentication logic for Flutter + Nestjs
