| title: "(datapipe) Build ETL: connect source, create transform, set up sink, schedule" |
| difficulty: hard |
| category: custom_cli |
| description: | |
| Using the datapipe CLI, build an ETL pipeline that extracts user activity |
| data from a PostgreSQL source, transforms it to compute daily active user |
| metrics, and loads the results into an Elasticsearch sink. Create a source |
| connection to the PostgreSQL database "analytics_db" on host |
| "db.internal:5432". Create a transform step that aggregates user events |
| by day and computes unique user counts. Create a sink connection to |
| Elasticsearch cluster "es.internal:9200" targeting the index |
| "user_metrics". Wire these into a pipeline called "daily-dau-pipeline" |
| and schedule it to run daily at 02:00 UTC. |
