Teiid 10.0.0.Alpha2 Released

Teiid 10.0.0 Alpha2 has been released.  Feature work is still ongoing. There's been progress on on Spring Boot support and an OrientDB translator.

Re-licensing to ASL2 is now complete, and the initial set of Couchbase issues have been addressed.

Special thanks to dalex dalex for raising several planning issues.

Other News:
  • We have started to utilize the Maven Central Repository and use the org.teiid group instead of org.jboss.teiid.  Only the main project has been converted so far.  There are no plans as of yet to change the JBoss Module names.
  • Teiid 9.2.5 will be available by the end of week.

  • Teiid 9.3.1 will be available in the next week.

Teiid 9.3 Final Released

With about 3 1/2 months of work, 138 issues later, 9.3 Final release is ready.  Feature highlights include:
  • TEIID-3624 CREATE DOMAIN support for user-defined simple types.
  • TEIID-4724 DDL .vdb deployment.
  • TEIID-4557 TEIID-2465 Memory restrictions at the operation and session level.
  • TEIID-4578 SQLAlchemy and Superset support through our pg/odbc access.
  • TEIID-4646 LEAD/LAG/FIRST_VALUE/LAST_VALUE analytic/value function support.
  • TEIID-2820 Couchbase support via a new translator and resource adapter.
  • TEIID-4733 Infinispan Support via a new translator and resource adapter.
There were also several important planning issues that were resolved including: More join pruning and left outer join optimization.

DDL VDB support has been enhanced to be nearly equivalent to of its XML counterpart.  We will continue to improve the usability, feature set, and refine the syntax when necessary.

UI Work

If you haven't seen it, please also check out Data Service Builder - which is a streamlined web UI for JDV/Teiid. We will release a Designer version based on Teiid 9.3 in near future. However after that Designer will be mostly in maintenance mode.  We are going to focus more on Web-based UI for future.

10.x and Beyond

Although initially slated for 9.3 change data capture (CDC) event handling based on Debezium to keep the materialization tables in sync with source data sources like MySQL and PostgreSQL will be delayed until 10.0 or later.

With the emergence of Cloud-based processing and Microservices architectures, we have been taking a hard look at Teiid and how we could progress technology into future. We have laid out some initial plans about our thinking and some immediate actions. We are soliciting your input all these matters, so please get involved so that we can shape Teiid together.

Thanks again to everyone who contributed to this release.
