Teiid 9.0 Beta2 Released

Teiid 9.0 Beta2 is now available. The main feature in Beta2 since Alpha1:

TEIID-3725 JDG Cache/DSL Translator added cache swapping feature to support external materialization.
TEIID-3810 JDG Cache/DSL Translator upgraded support for JDG 6.6
TEIID-3520 Swagger Translator for calling REST services defined by Swagger.

Things will be a little slow this week as the core devs are meeting face to face, but we're making a lot of progress on planning. Thanks again for all the community issues and posts - a special thanks to Marco Ardito for helping diagnosing ODBC issues and working with other community members.

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.
