Teiid 8.2 正式版终于发布了，这个版本花费了我们超过 12 周的时间，它终于来了，带来很多激动人心的特：
这些特性包括：
OData Support
JSON Support
Source Temp Tables
Teiid 8.3 依然基于 JBoss AS 7.1.1，下一个 8.4 版本将基于 EAP 6.1.x，将会带来如下新特性：
TEIID-2253 Multi-source improvements - multi-source planning was significantly improved, which will result in much better plans when using multi-source models. The user may also now configure the multi-source column name, auto-populate the multi-column in the actual metadata, and use non-literal multi-source column values.
TEIID-1557 Generated Key Retrieval - JDBC now supports generated key retrieval, see the Client and the Developers Guides for more.
TEIID-2311 Permission Conditions - data roles can now specify SQL conditions that will enforce row-based security and physical table insert/update checked constraints. See the Reference Guide for more.
TEIID-2341 Join Planning Improvements - ANSI join structures can now be preserved with the preserve hint, i.e. FROM /*+ PRESERVE */ (tbl1 INNER JOIN tbl2 ON ...), which is similar to the Oracle ORDERED hint. Also sources restricted to only outer joins (such as Salesforce) can have INNER or effectively INNER joins pushed to them.
TEIID-2312 Source security domains - Ldap, Salesforce, google-spreadsheet and ws (basic auth) translators can now define "security-domain" in their resource-adaptor configuration for security. When defined along with caller-identity the logged in user's credentials are passed to source for authentication.
TEIID-2182 Events - Capture the VDB loading and unloading events now from registering a listener on EventDistributor
TEIID-2241 CLI script for Standalone - Install Teiid into any AS7 standalone configuration using the provided CLI script.
TEIID-2152 Basic MERGE support - support for a simplistic MERGE statement was added. See the Reference for more.
TEIID-1757 OData Translator - A translator for OData based sources has been added.
TEIID-1854 OData Transport - Access any deployed VDB into Teiid using OData protocol, essentially Teiid is now a OData server.
TEIID-2363 Concurrent Join Processing Enhancements - both sides of a join will processed more when possible. See also the org.teiid.joinPrefetchBatches system property in the Admin Guide.
TEIID-196 Source Temporary Tables - temporary (locally scoped) tables may be defined at runtime against physical sources with a CREATE FOREIGN TEMPORARY TABLE statement. See the Reference for more.
TEIID-2159 JSON Production - added the JSONARRAY, JSONARRAY_AGG, JSONOBJECT, and JSONPARSE constructs for producing JSON. See the Reference for more.
TEIID-2248 Bulk Salesforce Inserts - added the ability for the Salesforce translator to perform bulk inserts.
