Teiid 8.11 Beta1 and 8.10.1 Released

Teiid 8.11 Beta1 is now available from the downloads and maven.  Feature highlights since Alpha2 include:
  • TEIID-3434 More caching control over ttls in the result set cache down to the schema/table level.
  • TEIID-3412 MS Access support via the UCanAccess driver.
The UCanAccess support is necessary for those running on Java 1.8 as the JDBC ODBC bridge has been removed from the JRE.

The waiting continues on EAP 6.4 Alpha1 - it still should be available shortly and should be the platform target for Teiid 8.11 Beta2.

Of course, let us know if you find any issues with these early releases.  There's still plenty of time to get fixes into the final release.

Teiid 8.10.1 is also available.  It addresses 5 important issues discovered since 8.10 was released:
  • [TEIID-3409] - PostgreSQLExecutionFactory TranslatorProperty annotation in wrong place
  • [TEIID-3437] - Inconsistencies with row count handling
  • [TEIID-3438] - Null value returned from BlobImpl getBytes
  • [TEIID-3450] - bulk values are set directly from client
  • [TEIID-3400] - Oracle connection not consistently usable after cancel 
Thanks again for all the community support.

Teiid 8.11 Alpha2 Released

Teiid 8.11 Alpha2 is now available from the downloads and maven.  Feature highlights since Alpha1 include:
  • TEIID-3393 Embedded AdminApi is now available from EmbeddedServer.getAdmin.
  • TEIID-3270 Virtual Functions can not be defined with procedure syntax.
EAP 6.4 Alpha1 should be available shortly and should be the platform target for Teiid 8.11 Beta2.

Expect an 8.10.1 release around the same time as 8.11 Beta2.  This will address important issues with 8.10 found after the release.

Thanks again for all the community support.  There has been a rash of spam attacks against the forums of late, so please be patient if you encounter any issues with posting.

OReva - Fork of OData4J library

Teiid community depends upon OData4J for its V2 implementation of the OData protocol. We see that there has been not much activity in OData4J project for last 2 years, so we consider this is project is effectively dead by all means. However, Teiid community still on hook to support our OData V2 implementation for little while longer (I see at least 2 yrs), for that reason we have forked this project and calling it "OREVA".

I have somewhat simplified the offering by removing the JDBC and JPA as we do not use those modules, but rest of core protocol is intact. We will try to keep it up with any bug fixes and maintenance. So, if you are wanting to submit a patch or work on some enhancements you can always come and talk to us,  patches are Welcome.

Here is the fork   If there is enough interest form OData4J remaining community, I do not mind moving this to different GitHub organization other than Teiid. If you find a issue, use  for now we are using Teiid's issues system.

I also would like to thank John Spurlock for his all his contributions towards OData4J, Thank you. It is a very good OData framework

Thank you.


Teiid 8.11 Alpha1 Released

After a two week delay we're ready to release 8.11 Alpha1 - now available from the downloads and maven.  Feature highlights include:
  • TEIID-3372 Multiple metadata - elements can now be used to configure a vdb.
  • TEIID-3369 Custom query rewrite - via a configurable PreParser.
  • TEIID-3389 Kerberos Delegation JDBC driver can now participate in kerberos delegation based authentication
  • TEIID-3390 SQL/XML improvements in performance and disk utilization.
  • TEIID-3362 ARRAYITERATE system procedure for iterating over an array.
Other things of note:
EAP 6.4 Alpha1 is still not quite properly available in the community - which is the primary reason for our delay. We'll continue to work with them to get so that we can retarget 8.11 to 6.4 as early as possible.

Progress with Olingo has slowed. Their community may not get to a final release in a timely fashion and they have slowed in working with Ramesh on patches.

We now have our own fork of OData4j, which will give us a proper community place for patches and other work -

Thanks for all the community efforts. We have a pending contribution of Redis connectivity from Devin Pinkston and of course have been working hard to address any issues found post 8.10.

Authenticating datasources with LDAP or Kerberos in Amazon AWS

This blog is mainly to showcase one of the community success story with Teiid and Amazon AWS. The need for our community user Ben Kibler was to provide data sources in AWS be participating in Kerberos authentication. Not only participating, he wanted to provide a consistent usage and access pattern, and a light weight integration layer  for these data sources.

He choose Teiid embedded for this purpose, and provided an extension to hook Auth services back into their corporate Active Directory.  With that his applications can participate in kerberos auth with Teiid, and then same token will be delegated to underlying data sources in Amazon AWS. The rest was provided by Teiid.

Read more about it and find the supporting code at

We love to here about your success stories on Teiid. Also, if something is not working for you as you expect, then come engage us in a discussion, together we can solve the issue the OSS way!

Thank You BenK.
