TIBCO eFTL Subscribe Input Adapter

This adapter requires access to the JAR file that implements the TIBCO eFTL Java API on your system, and any files referenced by that JAR file. The adapter has been tested with eFTL version 3.4.0, though it will likely work with newer FTL API versions as well. To make the TIBCO FTL Java API available to the adapter, you must supply a maven dependency for it. The eFTL sample comes with a launch config tibeftl jar maven install to repo.launch which will install the tibeftl.jar into your local maven repository. Run the launch config, and respond to the prompt for both the location of tibeftl.jar and the version number it represents by right clicking tibeftl jar maven install to repo.launch and performing the Run As command.

Name: Use this required field to specify or change the name of this instance of this component, which must be unique in the current EventFlow module. The name must contain only alphabetic characters, numbers, and underscores, and no hyphens or other special characters. The first character must be alphabetic or an underscore.

Operator: A read-only field that shows the formal name of the operator.

Class name: Shows the fully qualified class name that implements the functionality of this adapter. If you need to reference this class name elsewhere in your application, you can right-click this field and select Copy from the context menu to place the full class name in the system clipboard.

Start options: This field provides a link to the Cluster Aware tab, where you configure the conditions under which this adapter starts.

Enable Error Output Port: Select this check box to add an Error Port to this component. In the EventFlow canvas, the Error Port shows as a red output port, always the last port for the component. See Using Error Ports to learn about Error Ports.

Description: Optionally enter text to briefly describe the component's purpose and function. In the EventFlow Editor canvas, you can see the description by pressing Ctrl while the component's tooltip is displayed.

The advanced tab contains advanced connection options.

The schema lets you set up the fields that will be pulled from the eFTL messages. It is not required to provide all fields that may be in a message. The system matches fields by name and only converts data for fields specified in the schema; other fields in the eFTL message are ignored. If you subscribe to two subscriptions with different message formats, you can create a superset schema to be able to handle both subscriptions on a single adapter, if required (although using separate adapters for each is a preferred method).

Use the settings in this tab to allow this operator or adapter to start and stop based on conditions that occur at runtime in a cluster with more than one node. During initial development of the fragment that contains this operator or adapter, and for maximum compatibility with TIBCO Streaming releases before 10.5.0, leave the Cluster start policy control in its default setting, Start with module.

Cluster awareness is an advanced topic that requires an understanding of StreamBase Runtime architecture features, including clusters, quorums, availability zones, and partitions. See Cluster Awareness Tab Settings on the Using Cluster Awareness page for instructions on configuring this tab.

Use the Concurrency tab to specify parallel regions for this instance of this component, or multiplicity options, or both. The Concurrency tab settings are described in Concurrency Options, and dispatch styles are described in Dispatch Styles.

This section describes how data is converted from eFTL Data objects into a tuple result. Note that the best data conversion option is highlighted.

If the StreamBase data type is not correct, the field will not be converted and will be left null.
