IgniteConfiguration resolveProperty Placeholders (advanced) Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true boolean The Ignite Queues endpoint is configured using URI syntax: with the following path and query parameters: 161.1.1. Path Parameters (1 parameters): Name Description Default Type name Required The queue name. String 161.1.2. Query Parameters (7 parameters): Name Description Default Type capacity (producer) The queue capacity. Default: non-bounded. int configuration (producer) The collection configuration. Default: empty configuration. You can also conveniently set inner properties by using configuration.xyz=123 options. CollectionConfiguration operation (producer) The operation to invoke on the Ignite Queue. Superseded by the IgniteConstants.IGNITE_QUEUE_OPERATION header in the IN message.

Default: no timeout. Long treatCollectionsAsCache Objects (producer) Sets whether to treat Collections as cache objects or as Collections of items to insert/update/compute, etc. false boolean synchronous (advanced) Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). false boolean 161.2.

Name Description Default Type camel.component.ignite-queue.configuration-resource Sets the resource from where to load the configuration. It can be a: URI, String (URI) or an InputStream. The option is a java.lang.Object type. String camel.component.ignite-queue.enabled Enable ignite-queue component true Boolean camel.component.ignite-queue.ignite Sets the Ignite instance. The option is a org.apache.ignite.Ignite type. String camel.component.ignite-queue.ignite-configuration Allows the user to set a programmatic IgniteConfiguration. The option is a org.apache.ignite.configuration.IgniteConfiguration type.

Only properties which are of String type can use property placeholders. true Boolean 161.2.1. Headers used This endpoint uses the following headers: Header name Constant Expected type Description CamelIgniteQueueOperation IgniteConstants.IGNITE_QUEUE_OPERATION IgniteQueueOperation enum Allows you to dynamically change the queue operation. CamelIgniteQueueMaxElements IgniteConstants.IGNITE_QUEUE_MAX_ELEMENTS Integer or int When invoking the DRAIN operation, the amount of items to drain. CamelIgniteQueueTransferredCount IgniteConstants.IGNITE_QUEUE_TRANSFERRED_COUNT Integer or int The amount of items transferred as the result of the DRAIN operation. CamelIgniteQueueTimeoutMillis IgniteConstants.IGNITE_QUEUE_TIMEOUT_MILLIS Long or long Dynamically sets the timeout in milliseconds to use when invoking the OFFER or POLL operations.
