Connector for RabbitMQ

The RabbitMQ connector allows connection to RabbitMQ’s message bus on a real-time streaming basis. Specifically, the connector allows Panopticon to subscribe to XML, JSON, Text or FIX based messages that are published on particular topics.

Enter the connection details:

Property	Description
Broker	The location of the message broker.
User Id	The user Id that will be used to connect to RabbitMQ.
Password	The password that will be used to connect to RabbitMQ.

Select any of the following Exchange Types:

Exchange Type	Description
Default	A direct exchange with no name that is pre-declared by the broker. Selecting this exchange type disables the Exchange section (Exchange and Routing Key properties).
Fanout	Broadcasts all the messages it receives to all of the queues it knows, and the routing key is ignored (the Routing Key field is disabled).
Direct	Delivers messages to queues based on a message routing key. It is ideal for the unicast routing of messages, although it can be used for multicast routing as well.
Topic	A message sent with a particular routing key will be delivered to all the queues that are bound with a matching binding key.
Headers	Exchanges routed based on arguments containing headers and optional values.

Depending on the selected Exchange Type, select or define the following:

Property	Description
Exchange	Name of the exchange.
Durable	Enable so the exchange can survive a broker restart.
Auto Delete	Enable so the exchange is deleted when the last queue is unbound from it.
Routing Key	The routing key used to deliver messages to queues.
Headers	This field is only available when the message type is Header. Binding a queue to a Headers exchange is possible using more than one header for matching. Setting x-match to any means just one matching value is sufficient. Setting it to all means that all values must match. Default is x-match=all.

Select the Explicit Queue checkbox and enter the custom queue name. Then enter or enable
the following properties:

Queue Property	Description
Properties	The custom queue property.
Durable	Enable so the queue can survive a broker restart.
Auto Delete	Enable so the queue that had the least consumer will be deleted when that connection closes.

Select the Message Type.
Select either the dot (.) or comma (,) as the Decimal Separator.
NOTE: Prepend 'default:' for the elements falling under default namespace.
Click to the fetch the schema based on the connection details. Consequently, the list of columns with the data type found from inspecting the first ‘n’ rows of the input data source is populated and the Save button is enabled.
This also populates the Id Column with the set of columns, of arbitrary type, that can be concatenated to form a unique row identifier.
You can also opt to load or save a copy of the column definition.

Click

to add columns to the RabbitMQ connection that represent sections of the message. Then enter or select:

Property	Description
Name	The column name of the source schema.
Fix Tag/JsonPath/Text Column Index/XPath	The Fix Tag/JsonPath/Text Column Index/XPath of the source schema.
Type	The data type of the column. Can be a Text, Numeric, or Time
Date Format	The format when the data type is Time.
Enabled	Determines whether the message field should be processed.
Filter	Defined parameters that can be used as filter. Only available for JSON, Text, and XML message types.

NOTE: To parse and format times with higher than millisecond precision, the format string needs to end with a period followed by sequence of upper case S. There can be no additional characters following them.

For example: yyyy-MM-dd HH:mm:ss.SSSSSS

To delete a column, select or for all the column entries select the topmost , then click .

Date/Time values of output data and Date/Time inputs, where supported, is by default unchanged.

You can opt to define the Show in Timezone and Source Timezone settings.
