Atmos

Since Camel 2.15

Both producer and consumer are supported

Camel-Atmos is an Apache Camel component that allows you to work with ViPR object data services using the Atmos Client.

from("atmos:foo/get?remotePath=/path").to("mock:test");

Options

The Atmos component supports 7 options, which are listed below.

Name Description Default Type

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

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

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

uri (advanced)

The URI of the server for the Atmos client to connect to

String

fullTokenId (security)

The token id to pass to the Atmos client

String

secretKey (security)

The secret key to pass to the Atmos client (should be base64 encoded)

String

sslValidation (security)

Whether the Atmos client should perform SSL validation

false

boolean

The Atmos endpoint is configured using URI syntax:

atmos:name/operation

with the following path and query parameters:

Path Parameters (2 parameters):

Name Description Default Type

name

Atmos name

String

operation

Required Operation to perform. There are 5 enums and the value can be one of: put, del, search, get, move

AtmosOperation

Query Parameters (12 parameters):

Name Description Default Type

localPath (common)

Local path to put files

String

newRemotePath (common)

New path on Atmos when moving files

String

query (common)

Search query on Atmos

String

remotePath (common)

Where to put files on Atmos

String

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

exceptionHandler (consumer)

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

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange. There are 3 enums and the value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

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

uri (advanced)

Atomos server uri

String

fullTokenId (security)

Atmos client fullTokenId

String

secretKey (security)

The secret key to pass to the Atmos client (should be base64 encoded)

String

sslValidation (security)

Atmos SSL validation

false

boolean

Dependencies

To use Atmos in your camel routes you need to add the dependency on camel-atmos which implements this data format.

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-atmos</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

Integrations

When you look at atmos integrations, there is one type of consumer, GetConsumer, which is a type of ScheduledPollConsumer.

  • Get

Whereas there are 4 types of producers which are

  • Get

  • Del

  • Move

  • Put

Examples

These example are taken from tests:

from("atmos:foo/get?remotePath=/path").to("mock:test");

Here, this is a consumer example. remotePath represents the path from where the data will be read and passes the camel exchange to regarding producer Underneath, this component uses atmos client API for this and every other operations.

from("direct:start")
.to("atmos://get?remotePath=/dummy/dummy.txt")
.to("mock:result");

Here, this a producer sample. remotePath represents the path where the operations occur on ViPR object data service. In producers, operations(Get,Del, Move,Put) run on ViPR object data services and results are set on headers of camel exchange.

Regarding the operations, the following headers are set on camel exhange

DOWNLOADED_FILE, DOWNLOADED_FILES, UPLOADED_FILE, UPLOADED_FILES, FOUND_FILES, DELETED_PATH, MOVED_PATH;

Spring Boot Auto-Configuration

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

The component supports 8 options, which are listed below.
