StreamBase AdapterGroup Configuration

This article provides a reference for generating a StreamBase configuration file for a certain subset of adapters and operators, where the HOCON type is com.tibco.ep.streambase.configuration.adapter and the root object is AdapterGroup.

Most Spotfire Streaming adapters are configured with settings made in the Properties view of their components on the Studio canvas.

However, a small set of operators and adapters have more complex requirements. Prior to StreamBase 10.5.0, these complex requirements were specified with a configuration file named adapter-configurations.xml which had to reside in the Studio project's src/main/resources folder. As of 10.5.0, this XML format is deprecated in favor of the HOCON format described on this page.

Configuration files of this type and root object can be edited as usual with the StreamBase Configuration File Editor. StreamBase Studio also provides an Edit button in the Properties view of any supported adapter as a shortcut to the Editor.

Adapters and operators that are configurable using the AdapterGroup root object include:

TIBCO ActiveSpaces Operators	OPC UA Adapters
Apache Cassandra Operators	Python Operator
Cluster Topic Publisher and Subscriber Adapters	Apache Pulsar Adapters (Consumer, Producer)
CME iLink Order Routing Adapter	RabbitMQ Adapters (Consumer, Producer, Ack, Nack)
Diameter Client Adapters (Input, Output, Controller)	RTPP Adapters
Diameter Server Adapters (Input, Output, Controller)	Web Server Request Adapter
Apache HBase Operators	Web Output Adapter, Web Input Adapter
Apache Kudu Operators	Web Input Response Adapter, Web Server Request Adapter
MQTT Client Adapters (Publish, Subscribe, Ack)	WITS Adapter, WITS Controller Adapter

If your project contains an adapter-configurations.xml, Studio offers to convert it to HOCON format when you click the Edit button in the Properties view. Once converted, Studio:

Each configuration file must contain the following:

There is one root object in configuration files with type com.tibco.ep.streambase.configuration.adapter that affects the adapters and operators listed here:

This section shows the subordinate objects, properties, usage, and syntax for the AdapterGroup root object.

The following shows a sample configuration in HOCON format for the Diameter adapters. For additional configuration examples, see the applicable adapter page in the Adapters Guide, or operator in the Authoring Guide, respectively.
