Creating Solace Input Data Source

The Solace connector allows connection to Solace’s message bus on a real time streaming basis. Specifically, the connector allows Panopticon Streams to subscribe to messages that are published in particular topics in Solace and consequently, perform operational analytics.

Steps:

1.     In the New Data Source page, select Input > Solace in the Connector drop-down list.

 

2.     Enter the connection details including:

Property	Description

VPN Name	Message VPN name. Default is default.
User Id	The user Id that will be used to connect to Solace.
Password	The password that will be used to connect to Solace.

 

3.     Enter the Topic or the queue physical name.

4.     Select the Message Type. This will specify the format of the data within the message.

Aside  from the Fix, Json, Text, and XML message types, Protobuf is also supported in Solace.

Then click  to select the File Descriptor (.desc file) in the Open dialog.   

Property	Description
Schema Name	The Protobuf schema.
Type Name	The message of Protobuf type that will be sent to Kafka.
File Descriptor	The FileDescriptorSet which: ·         is an output of the protocol compiler. ·         represents a set of .proto files, using the --descriptor_set_out option.

 

5.     Select either the period (.) or comma (,) as the Decimal Separator.

NOTE	Prepend 'default:' for the elements falling under default namespace.

 

6.     Click  to the fetch the schema based on the connection details. This populates the list of columns with the data type found from inspecting the first ‘n’ rows of the input data source.
