[teiid-issues] [JBoss JIRA] (TEIID-1328) API request: Programatically modify the VDB

[Mark Addleman (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-1328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675259#comment-12675259 ] 

Mark Addleman commented on TEIID-1328:
--------------------------------------

Here's want I want to do:
1) A delegate translator caches the results of the delegate's getMetadata call by serializing the metadata store to disk
2) On VDB reload, the delegate translator provides the cached results using setMetadataStore instead of delegating the getMetadata call

The question is, what is the key I should use to name the serialized metadata store so that the delegating translator can provide the proper data in step 2?

Now, having gone through the code a little deeper, it looks like MetadataStore is a singleton and not per translator as I originally assumed.  Is this correct?  If so, it seems like we could cache the entire store in one operation and, on VDB reload, call setMetadataStore with the deserialized singleton on each getMetadata call.  A little hacky, but effective.

Alternatively, I think we could be more individualistic by using the schema name as a key to identify each individual connection/translator pair.  If that's the case, it would be convenient if you provided a public getSchema() method in the MetadataFactory.

> I'd like an API to programatically modify the VDB.  It would be ideal to modify the VDB using DDL through Teiid.  Our primary use case is accessing a dynamic set of datasources through Teiid.  When a datasource is added, we would INSERT the appropriate entries into MODEL, PROPERTIES, DATASOURCES tables.  Teiid would reread the appropriate metadata from the associated translators.
