Teiid 9.2.4 Released

Teiid 9.2.4 has been released.  7 issues were addressed:
  • [TEIID-4858] - hive translator is extremely slow
  • [TEIID-4838] - View with a union that projects nulls fails to resolve properly
  • [TEIID-4875] - Planning issue with multiple aggregate decompositions through a join tree
  • [TEIID-4913] - MetadataFactory is not replacing . in column names
  • [TEIID-4927] - Update dockerfile
  • [TEIID-4942] - Statement batch does not enforce autoCommitTxn
  • [TEIID-4953] - JOIN of CTEs fails if one of them is dependent and has window functions with inner DISTINCT in underlying queries
From here the pace of fix releases for 9.2 will begin to slow.  The next fix will be released in 6-8 weeks.  9.3.x will become the primary focus of support - expect a 9.3.1 in 2-3 weeks.

Also the first preview release of 10.0 will be due out in about 1.5 weeks.

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.

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.
