Jeremiah Lowin created AIRFLOW-1005: ---------------------------------------
Summary: Speed up Airflow startup time Key: AIRFLOW-1005 URL: https://issues.apache.org/jira/browse/AIRFLOW-1005 Project: Apache Airflow Issue Type: Improvement Affects Versions: 1.8.0 Reporter: Jeremiah Lowin Assignee: Jeremiah Lowin Priority: Minor Airflow takes approximately 1 second to import. It turns out that more than half the time is spend doing two things: importing Cryptography to create Fernet keys and importing Alembic. The first Cryptography import is in configuration.py and is only necessary if Airflow is generating a new airflow.cfg file (but currently gets run every time). Therefore it can be easily deferred. The second is in models.py to check if encryption is turned on. This can also be deferred until encryption checks are actually needed. Alembic is always imported even though it is only needed for running initdb() and upgradedb(). It can be lazily imported inside those functions. These simple changes reduce Airflow's startup time by half on my machine. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
