Azure

The Camel Components for Windows Azure Services provide connectivity to Azure services from Camel.

Azure components

See the following for usage of each component:

Azure Event Hubs

The azure-eventhubs component that integrates Azure Event Hubs using AMQP protocol. Azure EventHubs is a highly scalable publish-subscribe service that can ingest millions of events per second and stream them to multiple consumers.

Azure Storage Blob Service

Store and retrieve blobs from Azure Storage Blob Service using SDK v12.

Azure Storage Blob Service (Deprecated)

Store and retrieve blobs from Azure Storage Blob Service.

Azure Storage Queue Service

The azure-storage-queue component is used for storing and retrieving the messages to/from Azure Storage Queue using Azure SDK v12.

Azure Storage Queue Service (Deprecated)

Store and retrieve messages from Azure Storage Queue Service.

Spring Boot Auto-Configuration

When using azure 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-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 37 options, which are listed below.

Name Description Default Type

camel.component.azure-blob.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-blob.azure-blob-client

The blob service client. The option is a com.microsoft.azure.storage.blob.CloudBlob type.

CloudBlob

camel.component.azure-blob.blob-metadata

Set the blob meta-data

Map

camel.component.azure-blob.blob-offset

Set the blob offset for the upload or download operations, default is 0

0

Long

camel.component.azure-blob.blob-prefix

Set a prefix which can be used for listing the blobs

String

camel.component.azure-blob.blob-type

Set a blob type, 'blockblob' is default

BlobType

camel.component.azure-blob.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-blob.close-stream-after-read

Close the stream after read or keep it open, default is true

true

Boolean

camel.component.azure-blob.close-stream-after-write

Close the stream after write or keep it open, default is true

true

Boolean

camel.component.azure-blob.configuration

The Blob Service configuration. The option is a org.apache.camel.component.azure.blob.BlobServiceConfiguration type.

BlobServiceConfiguration

camel.component.azure-blob.credentials

Set the storage credentials, required in most cases. The option is a com.microsoft.azure.storage.StorageCredentials type.

StorageCredentials

camel.component.azure-blob.credentials-account-key

Set the storage account key used during authentication phase

String

camel.component.azure-blob.credentials-account-name

Set the storage account name used during authentication phase

String

camel.component.azure-blob.data-length

Set the data length for the download or page blob upload operations

Long

camel.component.azure-blob.enabled

Whether to enable auto configuration of the azure-blob component. This is enabled by default.

Boolean

camel.component.azure-blob.file-dir

Set the file directory where the downloaded blobs will be saved to

String

camel.component.azure-blob.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-blob.operation

Blob service operation hint to the producer

BlobServiceOperations

camel.component.azure-blob.public-for-read

Storage resources can be public for reading their content, if this property is enabled then the credentials do not have to be set

false

Boolean

camel.component.azure-blob.stream-read-size

Set the minimum read size in bytes when reading the blob content

Integer

camel.component.azure-blob.stream-write-size

Set the size of the buffer for writing block and page blocks

Integer

camel.component.azure-blob.use-flat-listing

Specify if the flat or hierarchical blob listing should be used

true

Boolean

camel.component.azure-blob.validate-client-u-r-i

Whether to validate the Azure client URI

true

Boolean

camel.component.azure-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-queue.azure-queue-client

The queue service client. The option is a com.microsoft.azure.storage.queue.CloudQueue type.

CloudQueue

camel.component.azure-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.
