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.

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.
