Teiid 9.1 Alpha2 Available

After a small delay Teiid 9.1 Alpha2 has been posted.  Notable features since Alpha1:
  • TEIID-4332 Improved NDV calculations for costing.
  • TEIID-2715 OData Metadata support for providing the metadata extension properties for OData.
Also the OData 2 service layer has been removed.  Please contact the community if you still need that functionality and want to maintain it as an independent project.

WildFly Upgrade

While most of the issues with the WildFly upgrade should be resolved.  It is unclear when progress will be made on TEIID-3834: start/stop of a data source or resource adapter requires a restart (somewhat worse behavior than WildFly 9 from our perspective)

Teiid Whipper

Whipper is a new project that will incorporate the changes made to our BQT testing framework by our Red Hat QE team and will aim to provide new features / ease of use for validation testing of all things Teiid.

Teiid Designer

Teiid Designer should have a release compatible with WildFly 9 / Teiid 8.13.x and Teiid 9.0.x in the next two weeks.  There is still no timeline yet for a Teiid Designer release compatible with WildFly 10.

The OpenShift web UI continues to progress, please contact their community is you have any interest in following or contributing to the work.

9.0.x

9.0.3 is due out in approximately 2-3 weeks.

8.13.x

If needed 8.13.7, the last fix release on 8.13, will be available by the general release of 9.1.

As always thanks for all the community support,
Steve

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

Teiid Spring Boot 1.7.0 Released

Teiid Spring Boot version 1.7.0 to support Teiid 16.0 has been released. This release is mainly to support the Teiid's latest version.  In this release, the support for OpenAPI code generation based on VDB has been removed as there is no community interest and moreover it was at OpenAPI 2.0, and the industry has moved to 3.0 and beyond. There are no plans to further pursue this feature. VDB maven plugin was also removed, which was intended to be a replacement for the VDB importing feature was to be used when working on OpenShift, however, since it requires the Maven repository and does not completely represent the feature as defined on the WildFly based deployments this is also removed. You can still use the VDB import feature with Teiid Spring Boot, simply define the VDB with your "IMPORT DATABASE" statements and provide the additional files along with the main VDB file. During the start of the application, Teiid Spring Boot will load all the necessary DDL files for the
