Teiid 8.1 CR1 Posted

By
Teiid 8.1 CR1 is now available for deployment on AS7 7.1.1-Final. We are excited to be closing in on the final release.  New features since Beta1 include: 
  • TEIID-1598 Translator Result Caching - translators can interact with the result set caching facility via a CacheDirective. See the Developer's Guide for more.
  • TEIID-2077 Result reuse - the engine will automatically detect if the same source query is used multiple times in a plan and reuse the result rather than issuing another query.
  • TEIID-2113 Misc parser improvements - the parser will now accept the LATERAL keyword for defining a LATERAL join (previously we just used the TABLE keyword), unary negation is now supported e.g. -col1, the FOR keyword is optional for TEXTAGG, and the BNF documentation was dramatically improved.
  • TEIID-2036 Dependent Join Array Comparison - platforms supporting array comparisons can have multi-attribute dependent joins pushed down as array comparisons. Oracle, PG, and H2 translators are already marked as supporting array types.
We are also closing in on addressing nearly 100 issues, which should ensure a high quality release shortly.

Please ensure that all of your issues have been addressed satisfactorily in the next week and of course log anything new that you find.

Teiid Spring Boot 1.7.0 Released

By
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

Expose Excel Data as OData feed using Teiid

By
For that matter you can expose any data source that is supported by Teiid through its translators as OData service. You can convert Relational databases XML, JSON, CSV files Web Services  Sales Force Excel documents sources, or write your on top of your specific source. Teiid added support for exposing its virtual database (VDB) as OData service without any additional work. Create a virtual database with your required sources and create any additional views and deploy in the the JBoss EAP 6.1 server, that has Teiid 8.3 or greater installed.  See https://docs.jboss.org/author/display/teiid84final/OData+Support  for more information. So, lets build a simple example of exposing the Excel Sheet. Teiid accesses Excel sheets via JDBC-ODBC bridge, and Windows OS provides a ODBC driver for Excel documents.  Edit the standalone-teiid.xml, and create Connection Factory jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};Dbq=c:\ODBC\ExcelData.xls odbc
