Subject [jira] [Commented] (ATLAS-2298) OCF JDBC Connector for GaianDB
Date Fri, 05 Jan 2018 09:57:00 GMT


Yao Li commented on ATLAS-2298:

1) I would find it useful to understand the use cases for this connector.I assume the 2 main
use cases are to query and to define new Logical tables (the new views), is adding GaianDB
data sources in scope? 

This JDBC Connector is only used by now for querying data from GaianDB. It is a sub class
of OCF connector. I will add a use case diagram to the document.

2) It would be useful to see how the DB_ parameters map to the actual JDBC url that will be

I will later upload the patch for review. [~davidrad]

3) I am wondering how the security works
       - are you using impersonation - if so how does this work?
       - if we are using certificates - does this connector need to know anything about them.

Nigel used the impersonation solution. The detailed information can be found in Ranger-1850

4) It would be useful to understand and document what is assumed to be running and setup for
the connector to work. 
     - I assume we need a running GaianDB instance.  
     - I assume the OCF needs to have the GaianDB connector defined. 
When we use the GaianDB JDBC Connector, we need the running GaianDB instance and the GaianDBJDBCConnector(the
name will be discussed) is a sub class of OCF. It has all the functions of OCF but for data

Thank you very much for your comments. [#Dav]
