Teiid invades the community.

We are very proud to announce a new open source project, "Teiid" under JBoss.org's community of projects. Teiid is a data virtualization system that allows applications to use data from multiple, heterogeneous data stores and provides you with single view of that data. Teiid (pronounced Tee - id) is also a whiptail lizard.

Although the Teiid project is new to open source, the Teiid technology has been around for many years under the "MetaMatrix" brand name. Red Hat acquired "MetaMatrix" in April 2007 and committed to open sourcing the technology and Teiid is result of that effort.

During this transition time, Teiid has gone though several major updates in its technology
  • SVN migration
  • Projects consolidation, refactoring into manageable components.
  • Use Maven for build system
  • Replacement of transaction framework to "JBoss Transactions"
  • Use of JBoss Cache for caching and clustering needs.
  • Upgrade to Java 1.6
  • Re-write of Query Processing Engine
  • Major updates to Query Optimizer code.
  • New project web site
  • New issue tracking system
  • Teiid Designer upgraded to Eclipse 3.4.1
  • Teiid Designer is deployed as Eclipse plug-in

and many more smaller features. For more information on Teiid project please visit http://www.teiid.org or http://www.jboss.org/projects/teiid

Many more new features are planned in our roadmap, so give it try and let us know how Teiid can satisfy your enterprise data virtualization needs.

Thank you.

Teiid Team.

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 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
