Teiid 8.8 for EAP 6.1 Alpha is now available. The main features are:

  • TEIID-2647 Translator for Cloudera's Impala data warehouse has been added. See the reference for more.
  • TEIID-2902 More incremental joins where the whole dataset does not need fully sorted or even read.
  • TEIID-2263 More control over MAKE (NOT) DEP hints via syntax that allows for traversing views. See the reference for more.
  • TEIID-2263 Common Table (WITH) planning improvements such that the usage of a WITH clause in a view or inline view no longer inhibits planning as part of the larger query.
  • TEIID-2980 XMLTable Array Support - XMLTABLE may now return arrays for sequence values.
  • TEIID-1675 Updatable LDAP multi-valued attributes - using an array type mapping, LDAP multi-valued attributes can be inserted/updated.
  • TEIID-3018 System tables for view/procedure defintions - the SYSADMIN Views and StoredProcedures tables can be used to access the defintions of the views/procedures.

Teiid is a data virtualization system that allows applications to use data from multiple, heterogenous data stores.


Teiid is comprised of tools, components and services for creating and executing bi-directional data services.  Through abstraction and federation, data is accessed and integrated in real-time across distributed data sources without copying or otherwise moving data from its system of record.

Teiid Parts

Query Engine The heart of Teiid is a high-performance query engine that processes relational, XML, XQuery and procedural queries from federated datasources.  Features include support for homogeneous schemas, heterogeneous schemas, transactions, and user defined functions.
Embedded An easy-to-use JDBC Driver that can embed the Query Engine in any Java application.
Server

An enterprise ready, scalable, managable, runtime for the Query Engine that runs inside JBoss AS that provides additional security, fault-tolerance, and administrative features.

Connectors

Teiid includes a rich set of Translators and Resource Adapters that enable access to a variety of sources, including most relational databases, web services, text files, and ldap.  Need data from a different source? A custom translators and resource adaptors can easily be developed.
