[teiid-issues] [JBoss JIRA] (TEIID-1971) Provide delegating Metadata Repository implementation class
[
https://issues.jboss.org/browse/TEIID-1971?page=com.atlassian.jira.plugin...
]
Ramesh Reddy resolved TEIID-1971.
---------------------------------
Resolution: Done
Instead of delegation model, I have created a stack/list model where multiple
MetadataRepositories can be concatenated to share responsiblity to load the metadata of
the given model.
This can be acived by providing a comma separated list of import types for ex:
{code:XML|title=Sample vdb.xml file}
<vdb name="{vdb-name}" version="1">
<model name="{model-name}" type="PHYSICAL">
<source name="AccountsDB" translator-name="oracle"
connection-jndi-name="java:/oracleDS"/>
<metadata type="NATIVE,DDL">
**DDL Here**
</metadata>
</model>
</vdb>
{code}
For the above model, _NATIVE_ importer is first used, then DDL importer used to add
additional metadata to _NATIVE_ imported metadata. It can also take custom module name as
the metadata repo names
See the User Defined Functions in Developer's guide for possible use cases.

Key: TEIID-1971
URL: https://issues.jboss.org/browse/TEIID-1971
Project: Teiid
Issue Type: Task
Components: Connector API
Affects Versions: 8.0
Reporter: Ramesh Reddy
Assignee: Ramesh Reddy
Fix For: 8.0
The Metadata Repository is interface defined to import metadata from variety of sources.
It is useful to provide a base implementation of of delegating metadata repository such
that it can be overridden by users to provide their own implementations, on top of already
already available methods.
