Teiid 7.6 CR1

By
7.6 CR1 is now available.  It fixes issues from the previous betas and contains the following new features: 
  • View removal hint - the NO_UNNEST hint now also applies to FROM  clause views and subqueries. It will instruct the planner to not perform view flattening.
  • Non-blocking statement execution - Teiid JDBC extensions TeiidStatement and TeiidPreparedStatement can be used to submit queries against embedded connections with a callback to process results in a non-blocking manner.
  • NON_STRICT limit hint - the NON_STRICT hint can be used with unordered limits to tell the optimizer to not inhibit push operations even if the results will not be consistent with the logical application of the limit.
  • Source Hints - user and transformation queries can specify a meta source hint, e.g. SELECT /*+ sh my-oracle:'leading' */ * FROM TBL. The hint information will be passed to the translator. The Oracle translator will by default treat the source hint as an Oracle hint.  See the Reference and Developers Guide for more.
  • Hive Translator - Hive translator has been added as a technology preview.
Please note that the weather web services example is no longer operational as the national weather service has modified their procedures.  We will have a replacement for the final release.

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
