             Summary: Add data retention to Airflow
                 Key: AIRFLOW-108
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-108
             Project: Apache Airflow
          Issue Type: New Feature
          Components: db, scheduler
            Reporter: Chris Riccomini


Airflow's DB currently holds the entire history of all executions for all time. This is problematic as the DB grows. The UI starts to get slower, and the DB's disk usage grows. There is no bound to how large the DB will grow.

It would be useful to add a feature in Airflow to do two things:

# Delete old data from the DB
# Mark some lower watermark, past which DAG executions are ignored

For example, (2) would allow you to tell the scheduler "ignore all data prior to a year ago". And (1) would allow Airflow to delete all data prior to January 1, 2015.
