Ignite ID Generator

Since Camel 2.17

Only producer is supported

The Ignite ID Generator endpoint is one of camel-ignite endpoints which allows you to interact with Ignite Atomic Sequences and ID Generators.

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

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.

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.

Component Options

The Ignite ID Generator component supports 5 options, which are listed below.

Name Description Default Type

configurationResource (producer)

The resource from where to load the configuration. It can be a: URL, String or InputStream type.

Object

ignite (producer)

To use an existing Ignite instance.

Ignite

igniteConfiguration (producer)

Allows the user to set a programmatic ignite configuration.

IgniteConfiguration

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

Endpoint Options

The Ignite ID Generator endpoint is configured using URI syntax:

ignite-idgen:name

with the following path and query parameters:

Path Parameters (1 parameters)

Name Description Default Type

name (producer)

Required The sequence name.

String

Query Parameters (6 parameters)

Name Description Default Type

batchSize (producer)

The batch size.

Integer

initialValue (producer)

The initial value.

0

Long

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)

The operation to invoke on the Ignite ID Generator. Superseded by the IgniteConstants.IGNITE_IDGEN_OPERATION header in the IN message. Possible values: ADD_AND_GET, GET, GET_AND_ADD, GET_AND_INCREMENT, INCREMENT_AND_GET.

Enum values:

  • ADD_AND_GET

  • GET

  • GET_AND_ADD

  • GET_AND_INCREMENT

  • INCREMENT_AND_GET

IgniteIdGenOperation

propagateIncomingBodyIfNoReturnValue (producer)

Sets whether to propagate the incoming body if the return type of the underlying Ignite operation is void.

true

boolean

treatCollectionsAsCacheObjects (producer)

Sets whether to treat Collections as cache objects or as Collections of items to insert/update/compute, etc.

false

boolean

Spring Boot Auto-Configuration

When using ignite-idgen 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-ignite-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.ignite-cache.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.ignite-cache.bridge-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.
