LiveView 10.4.3 Release Notes

These were the release notes for the TIBCO LiveView™ component of TIBCO® Streaming 10.4.3.

New Features

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


  • MQTT – MQ Telemetry Support

  • StreamBase Feed simulation

The connectivity wizard is available in Studio's File 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 autoincr field 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 autoincr attribute to a primary key. For example:

  <field ref="SequenceNumber" autoincr="true"/>

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.

Resolved Issues

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 Run As>EventFlow Fragment (or Debug As) 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.
