Salesforce Streaming API Input Adapter

Introduction

The TIBCO StreamBaseĀ® Input Adapter for Salesforce Streaming API allows StreamBase to connect to the Salesforce Streaming API and subscribe to a specific topic to streaming the topic in real time.

Use the Force.com Streaming API Developer Guide to set up example streams; the adapter can be used for both subject streams as well as generic streams based on topic and schema.

The adapter is written based on the Salesforce Streaming API v41.

Properties

This section describes the properties you can set for this adapter, using the various tabs of the Properties view in StreamBase Studio.

General Tab

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.

Adapter: A read-only field that shows the formal name of the adapter.

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.

Adapter Properties Tab

Property Type Description
Topic string The topic to listen to
Replay drop-down list Replay the topic from earliest, from tip, or from a specific index. If specific index is selected, then enter that index into the Replay Index field.
Replay Index int Replay the topic from the specific value
Timestamp Format string The timestamp format to use when converting date time objects to StreamBase timestamp data types
Log Level INFO Controls the level of verbosity the adapter uses to issue informational traces to the console. This setting is independent of the containing application's overall log level. Available values, in increasing order of verbosity, are: OFF, ERROR, WARN, INFO, DEBUG, TRACE.

Connection Tab

Property Type Description
Authentication Type drop-down list The authentication type to use, currently basic authentication is supported
Username string The username to be sent when logging in
Password string The password to be sent when logging in
Security Token string The security token to be sent when logging in
Login URL string The URL to access the Salesforce login
Max Buffer Size int The max buffer size to use while streaming
Max Network Delay int The max network delay to use while streaming
Keep Alive (Minutes) int The number of minutes between keep alive checks
Connection Timeout (Seconds) int The number of seconds before a timeout exception occurs during login
Proxy Host string The proxy host to use with this connection or blank to not use a proxy
Proxy Port int The proxy port to use with this connection which is used only when the proxy host has a value

Edit Schema Tab

Use the Edit Schema tab to declare the schema to match against the data payload of the streaming information that is sent for the topic selected. The topics JSON payload is loosely parsed into this schema, meaning fields in the JSON payload which are not represented in the schema are ignored.

Cluster Aware Tab

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.

Concurrency 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.

Caution

Concurrency settings are not suitable for every application, and using these settings requires a thorough analysis of your application. For details, see Execution Order and Concurrency, which includes important guidelines for using the concurrency options.
