Web-UI Enhancements

  • Improved User Experience

  • Undo/Redo Flow Changes

Driver Enhancements

  • Added support for Dynamic Relational DataSource Configuration

— A callback TDV procedure, that is implemented in SQL Script or as a custom Java procedure (CJP) and owned by TDV administrators, can be registered with a relational data source to apply runtime customizations to the data source properties configuration before a connection is used by the TDV server to establish a new session with the data source. All customizations are transient. Their scope is limited to the specification of the JDBC properties to be used by data source connections.
— As an example, an administrator could define a SQL Script procedure that determines the user associated with an incoming request accessing a relational data source and use TDV domain specific language (DSL) statements to adjust its JDBC connection properties to reflect what type of access - ReadWrite or ReadOnly - should apply to the data source connection used by the user request.

  • Vertica - text index

— Added support to create and drop text index in Vertica driver.
— The source table on which the index is to be created must have a primary key and an associated projection. It must also be both sorted and segmented by the primary key.
