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
