LiveView 10.4.0 Release Notes

Connected LiveView clients can now share queries to improve system performance. See Shared Client Queries for details. As a result, the LVSessionQueries system table now displays a shared query ID.

Expanding on the metadata store options introduced in release 10.3.0, LiveView resources can now be stored and loaded into the first running node in a LiveView cluster, whereby all similarly metadata store-configured LiveView nodes in the cluster can take advantage of those resources. See LiveView Metadata Store for details.

All LiveView system tables now support projections with simple expressions, including aliases.

LiveView adds the ability to determine whether a table supports group-by expressions by checking the GROUP_BY_EXPRESSIONS table capability. For more information on this table capability, refer to your LiveView Client API documentation.

LiveView now includes three new configurable privileges to allow specified user roles to perform alert rule actions that were created by themselves, when authentication is enabled. See LiveView Authentication and Authorization for details. The new privileges are:

The LiveView Advanced Alerting Sample now includes a cron-based alert example. See the sample's README for details.

The lv-util command was added to generate a StreamBase interface file on which an EventFlow application can be based for use with a LiveView data table.

The lv-util command assumes the interface generation capability of the previously deprecated lv-server command. See lv-util(1) for details.

The alert-table element of the lvconf XML specification that supports author-time alert configuration (also referred to as static alerts), is now deprecated and is expected to be removed in a future release.

The jdbc-table lvconf XML configuration type, which was previously announced in StreamBase 7.6.8 as deprecated, is now removed. Instead, use an External Server Connection of type JDBC.

When using Vertica as an external JDBC-compliant database, TIBCO recommends using versions 7.0-7.5.5, as detailed on the Supported Configurations page.

To avoid potential, known third-party Spring Framework vulnerabilities, LiveView's shipped Spring Framework version was updated to 4.3.17.

This release addresses an issue where the .NET client API could sometimes incorrectly report a network disconnection to the client. This was fixed such that all disconnections now cause a QueryExceptionEvent. Expect to see additional QueryExceptionEvents when using the .NET API client if you do not close queries before you close the connection.

Double-quoting expressions is no longer necessary in most expressions, and no change is required when running existing queries. However, this change can affect existing queries for WHERE expressions containing killpublisher, killquery, killsession, and addalertrule commands.

Previously, some command line expressions needed to be double-quoted. This is no longer necessary.
