String(5000) fields in model
[ https://issues.apache.org/jira/browse/AIRFLOW-607?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bolke de Bruin resolved AIRFLOW-607.
------------------------------------
Resolution: Won't Fix
Oracle is not a supported backend DB. We will accept a PR for this, but it is not a blocker/bug to us.
> Cannot initdb on Oracle because of String(5000) fields in model
> ---------------------------------------------------------------
>
> Key: AIRFLOW-607
> URL: https://issues.apache.org/jira/browse/AIRFLOW-607
> Project: Apache Airflow
> Issue Type: Bug
> Affects Versions: Airflow 1.7.1.3
> Reporter: Paul Luong
> Assignee: Paul Luong
> Priority: Blocker
>
> Unfortunately Oracle cannot be used to host the Airflow application DB due to the fact that Oracle limits varchar data types to 4000 bytes.
> If you try to run the airflow initdb command to install the DB onto Oracle you will end up with the following error:
> sqlalchemy.exc.DatabaseError: (cx_Oracle.DatabaseError) ORA-00910: specified length too long for its datatype
> [SQL: '\nCREATE TABLE connection (\n\tid INTEGER NOT NULL, \n\tconn_id VARCHAR2(250 CHAR), \n\tconn_type VARCHAR2(500 CHAR), \n\thost VARCHAR2(500 CHAR), \n\tschema VARCHAR2(500 CHAR), \n\tlogin VARCHAR2(500 CHAR), \n\tpassword VARCHAR2(500 CHAR), \n\tport INTEGER, \n\textra VARCHAR2(5000 CHAR), \n\tPRIMARY KEY (id)\n)\n\n']
> Request that we change String(5000) types in the Chart and Connection models to 4000.
> Thanks!
