Teiid 6.2 Released, packed with new features

The Teiid project team is excited to announce the release of version 6.2.0 - available for download here. The 6.2 release adds significant features in ease of use and enterprise readiness. It's never been easier to integrate your disparate enterprise data sources.

Dynamic VDB

An often requested feature, with a dynamic VDB data can be integrated between multiple sources very quickly without explicitly constructing a VDB using Teiid Designer. Check out a new example (dynamicvdb-portfolio) in the Teiid download, and read this blog for more info.

Introducing Teiid Server

In the prior releases of Teiid only an embedded deployment mode was offered. This meant the Teiid instance could not be shared among multiple clients. Now with Teiid server, you can run a standalone Teiid process and connect remotely over a highly scalable and configurable socket transport. Look here for installation instructions and how to connect to a server.


Multiple facets of security were added to help safe-guard your data.
  1. User Authentication: when enabled, users must be authenticated before they can access Teiid resources. You can configure a Teiid membership domain to plug into LDAP for authentication or use a simple file based authentication for development purposes. Visit identity support for more information.
  2. User Authorizations: access to Teiid can be controlled through specific grants of authorizations. These fall into two categories. "admin-roles" manage access to Teiid configuration and deployment. "data-roles" manage access to data exposed by a VDB. The latter is also called as "data entitlements", and can restrict data access up-to a "column" level. Visit managing authorizations for more information.
  3. SSL: when connecting to Teiid over the socket transport you can use SSL configured with your own certificates. See this.
  4. Encrypted Passwords: when defining data sources often the passwords are left in the clear text in the configuration files, Teiid provides a solution for encrypting them.

Logging has been bought under the management of Log4J. There are new logging contexts that allow you to capture SQL "commands" flowing through Teiid system and capture "audit" messages related to security and admin events. Learn more about how to manage logs here.

Admin Shell

Admin Shell is script based management tool for Teiid. Users can run Admin Shell in an interactive command line mode or script mode to connect, query and administer Teiid. Check out the Admin Shell Guide on documentation area and grab the binary in download area.

Many bugs, query constructs, and planning enhancements are also included in 6.2. Here is the complete list of changes. Take it for a test drive and let us now what you think.

Thank you

The Teiid Team.

Teiid 6.2 M3 and JBoss World slides

Teiid 6.2 M3 is now available. It fixes several issues from M2 and cleans up quite a bit of logic in the JDBC Connector. Next up RC1.

Have a look our presentation from JBoss World. It provides a good introduction to our internals - architecture, planning, processing, etc. If you have any questions feel free to post to the users list.
