Chapter 10. Azure Storage Queue Service

Both producer and consumer are supported

The Azure Storage Queue component supports storing and retrieving the messages to/from Azure Storage Queue service using Azure APIs v12. However in case of versions above v12, we will see if this component can adopt these changes depending on how much breaking changes can result.

Prerequisites

You must have a valid Windows Azure Storage account. More information is available at Azure Documentation Portal.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-azure-storage-queue</artifactId>
    <version>{CamelSBVersion}</version>
  <!-- use the same version as your Camel core version -->
</dependency>

10.1. URI Format

azure-storage-queue://accountName[/queueName][?options]

In case of consumer, accountName and queueName are required. In case of producer, it depends on the operation that being requested, for example if operation is on a service level, e.b: listQueues, only accountName is required, but in case of operation being requested on the queue level, for example, createQueue, sendMessage.. etc, both accountName and queueName are required.

The queue will be created if it does not already exist. You can append query options to the URI in the following format,

?options=value&option2=value&…

10.2. Configuring Options

Camel components are configured on two separate levels:

component level
endpoint level

10.2.1. Configuring Component Options

The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

Configuring components can be done with the Component DSL, in a configuration file (application.properties|yaml), or directly with Java code.

10.2.2. Configuring Endpoint Options

Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL as a type safe way of configuring endpoints.

A good practice when configuring options is to use Property Placeholders, which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse.

The following two sections lists all the options, firstly for the component followed by the endpoint.

10.3. Component Options

The Azure Storage Queue Service component supports 15 options, which are listed below.

Name	Description	Default	Type
configuration (common)	The component configurations.		QueueConfiguration
serviceClient (common)	Autowired Service client to a storage account to interact with the queue service. This client does not hold any state about a particular storage account but is instead a convenient way of sending off appropriate requests to the resource on the service. This client contains all the operations for interacting with a queue account in Azure Storage. Operations allowed by the client are creating, listing, and deleting queues, retrieving and updating properties of the account, and retrieving statistics of the account.		QueueServiceClient
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
createQueue (producer)	When is set to true, the queue will be automatically created when sending messages to the queue.	false	boolean
lazyStartProducer (producer)	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	boolean
operation (producer)	Queue service operation hint to the producer. Enum values: listQueues createQueue deleteQueue clearQueue sendMessage deleteMessage receiveMessages peekMessages updateMessage		QueueOperationDefinition
autowiredEnabled (advanced)	Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.	true	boolean
maxMessages (queue)	Maximum number of messages to get, if there are less messages exist in the queue than requested all the messages will be returned. If left empty only 1 message will be retrieved, the allowed range is 1 to 32 messages.	1	Integer
messageId (queue)	The ID of the message to be deleted or updated.		String
popReceipt (queue)	Unique identifier that must match for the message to be deleted or updated.		String
timeout (queue)	An optional timeout applied to the operation. If a response is not returned before the timeout concludes a RuntimeException will be thrown.		Duration
timeToLive (queue)	How long the message will stay alive in the queue. If unset the value will default to 7 days, if -1 is passed the message will not expire. The time to live must be -1 or any positive number. The format should be in this form: PnDTnHnMn.nS., e.g: PT20.345S — parses as 20.345 seconds, P2D — parses as 2 days However, in case you are using EndpointDsl/ComponentDsl, you can do something like Duration.ofSeconds() since these Java APIs are typesafe.		Duration
visibilityTimeout (queue)	The timeout period for how long the message is invisible in the queue. The timeout must be between 1 seconds and 7 days. The format should be in this form: PnDTnHnMn.nS., e.g: PT20.345S — parses as 20.345 seconds, P2D — parses as 2 days However, in case you are using EndpointDsl/ComponentDsl, you can do something like Duration.ofSeconds() since these Java APIs are typesafe.		Duration
accessKey (security)	Access key for the associated azure account name to be used for authentication with azure queue services.		String
credentials (security)	StorageSharedKeyCredential can be injected to create the azure client, this holds the important authentication information.		StorageSharedKeyCredential

10.4. Endpoint Options

The Azure Storage Queue Service endpoint is configured using URI syntax:

azure-storage-queue:accountName/queueName

with the following path and query parameters:

10.4.1. Path Parameters (2 parameters)

Name	Description	Default	Type
accountName (common)	Azure account name to be used for authentication with azure queue services.		String
queueName (common)	The queue resource name.		String

10.4.2. Query Parameters (31 parameters)

This client does not hold any state about a particular storage account but is instead a convenient way of sending off appropriate requests to the resource on the service. This client contains all the operations for interacting with a queue account in Azure Storage. Operations allowed by the client are creating, listing, and deleting queues, retrieving and updating properties of the account, and retrieving statistics of the account.		QueueServiceClient
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
sendEmptyMessageWhenIdle (consumer)	If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.	false	boolean
exceptionHandler (consumer (advanced))	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler

Required information options

To use this component, you have 3 options in order to provide the required Azure authentication information:

Provide accountName and accessKey for your Azure account, this is the simplest way to get started. The accessKey can be generated through your Azure portal.
Provide a StorageSharedKeyCredential instance which can be provided into credentials option.
Provide a QueueServiceClient instance which can be provided into serviceClient. Note: You don’t need to create a specific client, e.g: QueueClient, the QueueServiceClient represents the upper level which can be used to retrieve lower level clients.

10.5. Usage

For example in order to get a message content from the queue messageQueue in the storageAccount storage account and, use the following snippet:

from("azure-storage-queue://storageAccount/messageQueue?accessKey=yourAccessKey").
to("file://queuedirectory");

10.5.1. Message headers evaluated by the component producer

10.5.3. Advanced Azure Storage Queue configuration

If your Camel Application is running behind a firewall or if you need to have more control over the QueueServiceClient instance configuration, you can create your own instance:

StorageSharedKeyCredential credential = new StorageSharedKeyCredential("yourAccountName", "yourAccessKey");
String uri = String.format("https://%s.queue.core.windows.net", "yourAccountName");

QueueServiceClient client = new QueueServiceClientBuilder()
                          .endpoint(uri)
                          .credential(credential)
                          .buildClient();
// This is camel context
context.getRegistry().bind("client", client);

Then refer to this instance in your Camel azure-storage-queue component configuration:

from("azure-storage-queue://cameldev/queue1?serviceClient=#client")
.to("file://outputFolder?fileName=output.txt&fileExist=Append");

10.5.4. Automatic detection of QueueServiceClient client in registry

The component is capable of detecting the presence of an QueueServiceClient bean into the registry. If it’s the only instance of that type it will be used as client and you won’t have to define it as uri parameter, like the example above. This may be really useful for smarter configuration of the endpoint.

10.5.5. Azure Storage Queue Producer operations

Camel Azure Storage Queue component provides wide range of operations on the producer side:

Operations on the service level

For these operations, accountName is required.

Operation	Description
`listQueues`	Lists the queues in the storage account that pass the filter starting at the specified marker.

Operations on the queue level

For these operations, accountName and queueName are required.

Operation	Description
`createQueue`	Creates a new queue.
`deleteQueue`	Permanently deletes the queue.
`clearQueue`	Deletes all messages in the queue..
`sendMessage`	Default Producer Operation Sends a message with a given time-to-live and a timeout period where the message is invisible in the queue. The message text is evaluated from the exchange message body. By default, if the queue doesn`t exist, it will create an empty queue first. If you want to disable this, set the config `createQueue` or header `CamelAzureStorageQueueCreateQueue` to `false`.
`deleteMessage`	Deletes the specified message in the queue.
`receiveMessages`	Retrieves up to the maximum number of messages from the queue and hides them from other operations for the timeout period. However it will not dequeue the message from the queue due to reliability reasons.
`peekMessages`	Peek messages from the front of the queue up to the maximum number of messages.
`updateMessage`	Updates the specific message in the queue with a new message and resets the visibility timeout. The message text is evaluated from the exchange message body.

Refer to the example section in this page to learn how to use these operations into your camel application.

10.5.6. Consumer Examples

To consume a queue into a file component with maximum 5 messages in one batch, this can be done like this:

from("azure-storage-queue://cameldev/queue1?serviceClient=#client&maxMessages=5")
.to("file://outputFolder?fileName=output.txt&fileExist=Append");

10.5.8. Development Notes (Important)

When developing on this component, you will need to obtain your Azure accessKey in order to run the integration tests. In addition to the mocked unit tests you will need to run the integration tests with every change you make or even client upgrade as the Azure client can break things even on minor versions upgrade. To run the integration tests, on this component directory, run the following maven command:

mvn verify -PfullTests -DaccountName=myacc -DaccessKey=mykey

Whereby accountName is your Azure account name and accessKey is the access key being generated from Azure portal.

10.6. Spring Boot Auto-Configuration

When using azure-storage-queue with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-azure-storage-queue-starter</artifactId>
</dependency>

The component supports 16 options, which are listed below.

Name	Description	Default	Type
camel.component.azure-storage-queue.access-key	Access key for the associated azure account name to be used for authentication with azure queue services.		String
camel.component.azure-storage-queue.autowired-enabled	Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.	true	Boolean
camel.component.azure-storage-queue.bridge-error-handler	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	Boolean
camel.component.azure-storage-queue.configuration	The component configurations. The option is a org.apache.camel.component.azure.storage.queue.QueueConfiguration type.		QueueConfiguration
camel.component.azure-storage-queue.create-queue	When is set to true, the queue will be automatically created when sending messages to the queue.	false	Boolean
camel.component.azure-storage-queue.credentials	StorageSharedKeyCredential can be injected to create the azure client, this holds the important authentication information. The option is a com.azure.storage.common.StorageSharedKeyCredential type.		StorageSharedKeyCredential
camel.component.azure-storage-queue.enabled	Whether to enable auto configuration of the azure-storage-queue component. This is enabled by default.		Boolean
camel.component.azure-storage-queue.lazy-start-producer	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	Boolean
camel.component.azure-storage-queue.max-messages	Maximum number of messages to get, if there are less messages exist in the queue than requested all the messages will be returned. If left empty only 1 message will be retrieved, the allowed range is 1 to 32 messages.	1	Integer

camel.component.azure-storage-queue.service-client	Service client to a storage account to interact with the queue service. This client does not hold any state about a particular storage account but is instead a convenient way of sending off appropriate requests to the resource on the service. This client contains all the operations for interacting with a queue account in Azure Storage. Operations allowed by the client are creating, listing, and deleting queues, retrieving and updating properties of the account, and retrieving statistics of the account. The option is a com.azure.storage.queue.QueueServiceClient type.		QueueServiceClient
