-----------------------------------
Summary: Develope a JPA Translator
Key: TEIID-2011
URL: https://issues.jboss.org/browse/TEIID-2011
Project: Teiid
Issue Type: Feature Request
Components: Misc. Connectors
Reporter: Ramesh Reddy
Assignee: Ramesh Reddy
Fix For: 8.1
Provide a JPA based translator in Teiid. The main driving force for this is to support Hibernate OGM, which in turn uses big data stores like infinispan, EhCache as backing stores. Hibernate OGM also looking to expanding to other stores like Cassendra, MongoDB etc.
By providing JPA translator (think reverse hibernate), which provides
- Metadata
- Query API (JPQL)
which makes much easier for Teiid to identify data in big data stores and gives ways to integrate with other kinds of sources, both relational and non-relational. This usecase is limited to users who has defined their data using JPA and would like to use big data stores. Additional benefit of this is to provides full Relational access to a JPA store with JDBC/ODBC and SQL.
if the data in big data store is not in JPA objects, then see https://issues.jboss.org/browse/TEIID-1992

-------------------------------------
Summary: Projecting node issue
Key: TEIID-2094
URL: https://issues.jboss.org/browse/TEIID-2094
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 6.0.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Critical
Fix For: 8.1
If a non-pushed source node (inline view) is located over a projected node that needs to perform projection, a join node, or a select node, the resulting construction of the projection indexes will be incorrect or fail - as the input elements will not match the output elements that have been set to the views elements.

[JBoss JIRA] (TEIID-2105) VDB Status issue with redeploys
by Mark Drilling (JIRA)

------------------------------------
Summary: VDB Status issue with redeploys
Key: TEIID-2105
URL: https://issues.jboss.org/browse/TEIID-2105
Project: Teiid
Issue Type: Enhancement
Components: AdminApi
Affects Versions: 8.0
Reporter: Mark Drilling
Assignee: Steven Hawkins
I encountered this issue via Admin API. I found that when I deployed a VDB with View DDL definition I sometimes was not able to retrieve the VDB via the Admin API getVDBs method.
Steps to reproduce:
1) Deploy VDB with a valid JDBC source. works OK.
2) now, Add a View DDL defn to the VDB and redeploy it. For valid View DDL that references the JDBC source defined in 1), this works fine.
However, if I submit DDL that is a valid query - but references a non-existent source group - I get the following exceptions in the log
15:57:13,993 INFO [org.jboss.as.server.deployment] (MSC service thread 1-7) JBAS015876: Starting deployment of "MyVDB-vdb.xml"

After the above submittal of view DDL that references a non-existent source - the admin.getVDBs() call doesnt return anything. Normally I'd get the VDBMetaData, make changes and redeploy. But in this case, I do not get the previously deployed VDB.
