Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab:

• Stop Pipeline Execution: Stops the current pipeline execution when the Snap encounters an error.

• Discard Error Data and Continue: Ignores the error, discards that record, and continues with the rest of the records.

• Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Learn more about Error handling in Pipelines.

Label

String

Required. Specify a unique name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Default value: RabbitMQ Producer
Example: RabbitMQ Producer

Exchange

String/Expression

Specify the name of the RabbitMQ exchange used to

publish messages. If

you do not specify an exchange, the RabbitMQ server's default

exchange is used.

Default value: N/A
Example: Exchange1

Exchange type

Dropdown list

Choose the type of RabbitMQ exchange used to route the messages to the respective queues. Options available include:

• direct: routes messages to queues based on the Routing Key

• fanout: copies and routes a received message to all queues that are bound to it regardless of routing keys or pattern-matching

• headers: routes the messages based on arguments containing headers and optional values

• topic: routes messages to queues based on matches between the Routing key and Queue

Default value: direct
Example: fanout

Durable exchange

Checkbox

Select this checkbox to indicate the durability of the exchange

.

Default state: Selected

Queue

String/Expression

Specify the name of the RabbitMQ queue to which messages have to be pushed. If the queue with the specified name is not

existing on the RabbitMQ server,

a new queue is created and is bound to the exchange. If

there is no Queue name available, the Snap creates a temporary Queue name and uses it until the execution completes and deletes it as soon as the session expires.  
If the Routing key is specified,

the queue is bound to the exchange with the specified routing key, and only

messages with the specified routing key are pushed to the queue.

Default value: N/A
Example: Queue1

Create dynamic queue

Checkbox

Select this checkbox to generate a dynamic queue when the queue name is not provided. The Snap publishes the messages on the default (or specified) exchange and stores the messages in the dynamic queue until the session expires and the dynamic queue thus generated is deleted soon after.

When the dynamic queue is not selected with:

• Queue name provided

• : The Snap publishes the messages in the specified exchange.

• Queue name not provided

• : The Snap publishes the messages in the queue of the default exchange and stores the messages on the queue of that exchange type..

Default

state:

 Selected

Auto delete

Checkbox

Select this check box to indicate that the RabbitMQ autoDelete property associated with the existing queue is set to true.

Default

state: Deselected.

Routing Key

String/Expression

Optional. The routing key will be used to bound the queue with the exchange. Supply the Routing key

when the Exchange type is direct and topic to route the message to queues.

x-match

Dropdown list

Specify the x-match value to be submitted for binding. The available options are:

• any : If selected, even one matching header value is sufficient

• all : If selected, mandates that all the values should match

Default value: all

Wait for confirms timeout (ms)

Integer

Specify the timeout in milliseconds. The Snap waits until the message published since the last call has been acknowledged or not by the broker or, until the given timeout elapses.

For example, If the time set is 1000 ms, if the Snap does not get the

acknowledgment from the broker(Queue) for the published message until the given time, a timeout exception will be recorded.

Default value: 0
Example: 5

Header Properties

 This fieldset comprises the following fields:

• Header key

• Header value 

Header key

String/Expression

Speciy the name of the header that is being used for the binding.

Header value

 This fieldset comprises the following fields:

• Key

• Value 

Key

String/Expression

Specify the name of the message property. The message properties that can be added are:

• content-type

• delivery-mode: 1 (non-persistent), 2 (persistent)

Value

String/Expression

Specify the value for the message property.

Argument properties

Specify the custom argument properties to ensure all declarations for the queues use the same configuration/options/arguments.

This fieldset comprises the following fields:

• Argument key

• Argument value 

           Argument key

String/Expression

Specify the name of the argument used for declaration.

 See Optional Arguments

 x-queue-type

 Argument value

String/Expression

Specifies the value corresponding to

the argument key.

Default value: N/A
Example: 1048576, 2, quorum

Maximum connection attempts

Integer

Specify the maximum number of connection attempts in case of a connection failure. The Snap retries for the configured number of attempts

to establish the connection.

Default value: 3
Example: 5

Connection retry interval

Integer

Specify the time taken in seconds to wait before retrying for another connection.

Default value: 10
