LiveView 10.4.3 added the following updates and new features:
- New Connectivity Wizard
-
A new connectivity wizard available in Studio allows you to quickly stand up a LiveView server application for purposes of streaming live data to TIBCO Spotfire® X. You can use the wizard to configure a LiveView table to collect a window of streaming data from selected data sources, including:
-
Apache Kafka
-
JMS or TIBCO EMS
-
MQTT – MQ Telemetry Support
-
StreamBase Feed simulation
The connectivity wizard is available in Studio's menu. The wizard is largely self-documenting; see starting point documentation in the Concepts Guide on the Connectivity Wizard page.

- Auto-increment Option Now Added to LiveView Table Primary Key Field
-
LiveView tables can now specify a long data type, primary key field as an auto-increment field. The field remains like any other, excepting when rows are published to the table, the auto-increment field in the published row is ignored and an incrementing value substituted.
This effectively means the table will always add a new row on publish; updates to existing rows are not possible. Since primary keys can be multiple fields, you can use an
autoincrfield in combination with a timestamp field and guarantee that every arriving tuple is added as a new row, even if the timestamps happen to be the same for multiple rows.You can still delete rows through the publish path; in the delete case the field defined as auto-increment is not ignored and must be set to a matching value in the table.
In this release, enable the auto-increment feature by editing your data table's lvconf file in XML source mode to add the
autoincrattribute to a primary key. For example:<primary-key> <field ref="SequenceNumber" autoincr="true"/> </primary-key>
Support for this feature in Studio's forms-based LiveView Configuration File Editor is expected in an upcoming release.
- LiveView MQTT Recovery Publisher Sample Now Added
-
A new LiveView recovery publisher sample is now available. The sample demonstrates how data can be recovered and published to a LiveView table via an MQTT message bus.
This release included the following changes in functionality.
- LiveView Authentication and Authorization Sample Now Includes Optional LDAP Configuration
-
The LiveView Authentication Sample now includes optional, commented-out LDAP configuration.
- LiveView .NET Client API Updated
-
The .NET Client API was updated to include all current LiveView capabilities. For more information see .NET Client API documentation.
This section provides a list of errors corrected in release 10.4.3 of TIBCO LiveView™ component of TIBCO® Streaming. LiveView 10.4.3 inherited all fixes on the 2.2.x release branch through 2.2.7.
| Number | Resolution |
|---|---|
| CQS-4798 | In rare circumstances when an ORDER BY query result set had rows removed by a delete query — and when there were no continuous updates occurring — the expected LIMIT number of rows was sometimes not replenished. This resulted in smaller than expected result sets. |
| SB-46335 | In releases 10.4.0, 10.4.1, and 10.4.2, right-clicking an EventFlow module in a LiveView project and selecting > (or ) to run or debug the module independent of the enclosing LiveView project resulted in an error. This feature was restored starting in release 10.4.3. |
| SB-46276 | Since release 10.4.1, when LiveQL aggregate queries experienced underflow conditions, it was possible for subsequent add and remove events to be missed. This was fixed. |
