[jira] [Commented] (AIRFLOW-607) Cannot initdb on Oracle because of String(5000) fields in model

["Siddharth Anand (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AIRFLOW-607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15622849#comment-15622849 ] 

Siddharth Anand commented on AIRFLOW-607:
-----------------------------------------

Please submit a PR for this. I don't suspect we have a lot of Oracle users in the community so haven't seen this reported before now.

We use SQLAlchemy to generate the columns.

>                 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
>            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!
