    Release Notes for Teiid 6.1

    The Teiid 6.1 release focused on simplifing embedded deployment – especially for deployment in JBossAS as a DataSource.  In MetaMatrix most database connections were made through DataDirect drivers.  Vendor supplied drivers can now be used and the 6.1 release with confidence having gone through an internal vetting process for supported sources.

     

    New Features/Enhancements

     

    • Added more granular connector capabilities to allow for more pushdowns with LDAP and Salesforce connectors.
    • The XML relational connector uses streaming to process documents.  This allows for much larger documents to be processed without memory issues.
    • Added support for direct bulk updates to connectors, which are applicable to all update types, not just insert.
    • Cached plan sizes are significantly smaller allowing for larger prepared plan caches.
    • A partitioned merge join was added that does not fully sort the larger side of a merge join.
    • The SQLSTATE code is now reported to the client from source SQLExceptions.
    • Added not criteria support to the LDAP connector.
    • Added not and or criteria support to the Salesforce connector.
    • Enhanced subquery support - Added support for SELECT and JOIN criteria subquery pushdown,  subquery criteria can now be pushed through view layers, and subqueries are supported in any expression/predicate where applicable – previously subqueries were only support in the SELECT/WHERE clause of select statements.
    • Sort operations in sort/distinct/grouping/merge join nodes are now combined when possible.
    • Function resolving now can infer the function signature based upon the return type.  This removes the need for adding explicit converts around prepared statement parameters in some situations.
    • Distinct processing can be performed incrementally, which lowers initial query latency.
    • Added additional function pushdown support for SQL Server and PostgreSQL.
