Teiid 9.2 Alpha2 Available

Teiid 9.2 Alpha2 has been released. Due to the break and other issues this took slightly longer than anticipated.  Feature highlights since Alpha1:
  • TEIID-4532 Hashing Functions were added for md5, sha1, sha2-256, and sha2-512.
Feature Progress:

  • The DDL metadata system feature has been pared down to just TEIID-4629  
  • We're also putting more emphasis on materialization issues in anticipation of greater integration with Debezium.
Even if the features are not fully formed yet, the pace of fixes in general has been good as we're closing in on 70 issues.

Given the upcoming break, I don't expect the next pre-release until around January 6th.  Hopefully we'll be back to about every two weeks after than and stay on track for an early to mid February release.

Thanks,
Steve

The Teiid Tooling team has completed a Sprint 8 milestone for the Data Service Builder (DSB).

Data Service Builder (DSB) is a web interface that allows you to easily connect to your data, compose a data service, then test and deploy the data service for your applications to consume as an OData-based REST service.

See our Getting Started Page for instructions to download and try it out.   Also check out our Future Sprint Development Plans page.

Teiid 9.2 Alpha1 Released

Teiid 9.2 Alpha1 has been released.  Feature highlights so far:
In progress features:

  • Also using Teiid as a Postgres/Postgis source for qgis is nearly complete.
  • The build has been revamped to support our integration with WildFly Swarm.  Swarm provides a powerful new mechanism for embedding Teiid with the full power of the application server.  See an example/description at https://github.com/teiid/wildfly-swarm-teiid
  • It's not in this alpha, but a lot of work has been completed toward a more complete DDL metadata system.  Please follow this and other issues if you are interested in contributing.

We'll continue to shoot for a pre-release about every two weeks and still expect the final release in about 3 months.

Thanks,
Steve

Teiid 9.1.1 Released

Teiid 9.1.1 has been posted.  It addresses 7 issues:
  • [TEIID-3755] - Allow embedded to set the default authentication type
  • [TEIID-4499] - OData Kerberos cannot access VDB
  • [TEIID-4535] - Issues with EventDistributor
  • [TEIID-4541] - trustAllLocal works even for remote connections
  • [TEIID-4546] - On setting jboss-teiid cluster : throwing java.lang.IllegalArgumentException.
  • [TEIID-4547] - getQueryPlan fails in adminapi
  • [TEIID-4530] - Add semicolons to generated ddl
The most significant of which is a security issue - TEIID-4541.  If you are allowing remote JDBC connections, not using data roles, and have left trustAllLocal at the default setting, then remote connections that specify PassthroughAuthentication=true are also being allowed.  Please upgrade or alter your settings to prevent this.

The pace of fix releases for 9.0.x will now be much slower and end with the release of 9.2 Final.  The first alpha release of 9.2 should be available by the end of the week.

Thanks,
Steve
