Teiid 8.7 Final Released

Teiid 8.7 has been released and is now available for download and from the Maven repository.  This was both a rich feature and a fix release with over 100 issues addressed.

Main features in this release include:
  • TEIID-1070 Amazon SimpleDB support has been contributed by Radim Hopp. See the Admin and Reference Guides for more. See example here
  • TEIID-2761 Security Enhancements added support for a grant-all attribute on a role. Also added the ability to specify the security domain for a VDB. See the reference guide for more.
  • TEIID-2780 Apache Solr Translator has been added. See the Admin and Reference Guides for more. See example here
  • TEIID-2809 Pattern based system property substitution has been added to VDB.XML files. Only supported if the DVB is being deployed JBoss EAP.
  • TEIID-2844 Remove unauthorized columns from SELECT * can be enabled via the session property ignore_unauthorized_asterisk. See the Reference for more.
  • TEIID-2863/TEIID-2761 More robust GSS-API support. This issue also implements a feature where a user can now define a "security-domain" per VDB. User no longer has to depend upon the transport level authentication.
  • TEIID-2826 Revamped build structure for translators and connectors so that it is easier to package them and deploy them to a Teiid server.
  • TEIID-2859 TEXTTABLE FOR ORDINALITY a FOR ORDINALITY column can now be used with TEXTTABLE. See the Reference for more.
  • TEIID-965 Apache POI based Excel connectivity has been added. See the reference for more. See example here
  • TEIID-2888 Designer VDB support in Embedded is now available. With a few caveats, Designer .INDEX based vdbs can now be used with Teiid Embedded. See the Embedded Guide for more.
  • TEIID-2904 Translator Properties Translator import, override and extension-metadata properties are can retrieved through Admin API
  • TEIID-2627 Accumulo Translator has been added. See Admin and Reference guides for more information. See example here
We sincerely thank everyone who participated in the community.  All bugs/posts are helpful in refining Teiid.  We are looking forward to your input on 8.8.

If 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 8.11 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

Tech Tip: Teiid SQL Language MAKEDEP Hint Explained

In this article I will explain what a MAKEDEP hint is, how and when, why it should be used in Teiid. What: MAKEDEP is query hint.  When a query hint is defined in the SQL query it influences the Teiid query planner to optimize the query in a way that is driven by the user. MAKEDEP means "make this as a dependent join". What is a Dependent Join? For example if we have query like: SELECT * FROM X INNER JOIN Y ON X.PK = Y.FK Where the data for X, and Y are coming from two different sources like Oracle and WebService in Teiid, so in relational algebra you can represent above query as Here the result tuples from node X and node Y are being simultaneously fetched by Teiid query engine, then it joins the both the results inside Teiid engine based on the specified X.PK = Y.PK condition and returns the filtered resulted to the user. simple.. Now, what if, if X table has 5 rows and Y table has 100K rows? In order to do the JOIN naively Teiid need sto read all the 5
