Teiid 8.8 Final Released

We are pleased to announce the timely release of Teiid 8.8.  It is now available for download and from the Maven repository.  While we didn't quite make it to 100 issues, this release still has a good set of features and quite a few fixes.  Main features include:
  • TEIID-2647 Translator for Cloudera's Impala data warehouse has been added. See the reference for more.
  • TEIID-2902 More incremental joins where the whole dataset does not need fully sorted or even read.
  • TEIID-2263 More control over MAKE (NOT) DEP hints via syntax that allows for traversing views. See the reference for more.
  • TEIID-2263 Common Table (WITH) planning improvements such that the usage of a WITH clause in a view or inline view no longer inhibits planning as part of the larger query.
  • TEIID-2980 XMLTable Array Support - XMLTABLE may now return arrays for sequence values.
  • TEIID-1675 Updatable LDAP multi-valued attributes - using an array type mapping, LDAP multi-valued attributes can be inserted/updated.
  • TEIID-3018 System tables for view/procedure definitions - the SYSADMIN Views and StoredProcedures tables can be used to access the definitions of the views/procedures.
Thanks to everyone who helped in this release from the community - all bugs/posts are helpful in refining Teiid.  There was a lot of important OData feedback from Luca Gioppo, John Muller, Greg MacKinnon, and others.  Hopefully 8.9 will be the start of the OData v4 work - which will require all sorts of new testing.  

And now for the obligatory product plug - if you have been using Teiid and would like fully supported version, Red Hat has released Data Virtualization V6 (DV6).  The DV platform has comprehensive support from Red Hat including services/training.

Thanks,
Steve and Ramesh

Teiid 8.8 CR1

We are closing in on the 8.8 release with the availability of 8.8 CR1.   Notable features since Beta2 include:
  • TEIID-3018 System tables for view/procedure defintions - the SYSADMIN Views and StoredProcedures tables can be used to access the defintions of the views/procedures. 
We will also be kicking off Teiid 8.9 development shortly.  Expect more OData support in this release along with the usual performance improvements and fixes.

Please provide any feedback that you can on CR1 or vote/log issues for 8.9 and thanks again for all of the community support.

Kerberos authentication with Teiid

Teiid supports kerberos authentication over its JDBC and ODBC driver. It is also possible to configure OData access to use kerberos using SPNEGO with little amount of configuration.

Recently I wrote few articles while testing the feature, if interested see
  1. A practical "how-to" guide to Kerberos authentication with Teiid over JDBC
  2. A practical "how-to" guide to implement kerberos authentication with Simple REST Web App
  3. A "how to" guide to "delegate" kerberos token to REST based data source in Teiid
In article (1) shows how to configure Teiid to participate in Kerberos authentication.

In article (2) I showed a example to create simple web-app to configure with SPNEGO to participate in Kerberoes.

In article (3) I showed an example, to delegate the logged in user into Teiid, to the REST web-service as passthrough with out extra negotiation. 


Thanks

Teiid 8.8 Beta2

Teiid 8.8 Beta2 is now available from the downloads.  Features since Beta1 include:
  • TEIID-2980 XMLTable Array Support - XMLTABLE may now return arrays for sequence values.
  • TEIID-1675 Updatable LDAP multi-valued attributes - using an array type mapping, LDAP multi-valued attributes can be inserted/updated.
Over 70 issues have now been addressed in the release so we are expecting a high quality result by mid-July. Please provide feedback as early as possible so that the changes make it into the CR build.

Thanks again for all the feedback and forum questions. A general infrastructure issue that we are seeing is that there seem to be periods of time when we are not getting forum notifications. We do ordinarily strive to respond as quickly as possible.

Thanks,
Steve

Teiid 8.8 Beta1

Teiid 8.8 Beta1 has just been posted to the downloads.  Notable features since alpha1 include:
  • TEIID-2263 More control over MAKE (NOT) DEP hints via syntax that allows for traversing views.  See the reference for more.
  • TEIID-2263 Common Table (WITH) planning improvements such that the usage of a WITH clause in a view or inline view no longer inhibits planning as part of the larger query.
There has also been quite a bit of general issues addressed (including several with MongoDB), so this should be a fairly stable pre-release.  We have also seen that the Resteasy patch is now also required for SOAP WS translator/resource adapter operations, so please apply the patch proactively.

Thanks again for all the feedback.  Be sure to let us know of any issues as there is still plenty of time to get them addressed before the final release.

Thanks,
Steve
