|| Name || Default Value || Description ||
| {{strategyRef}} | | Refers to an [AggregationStrategy|http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/processor/aggregate/AggregationStrategy.html]
to be used to assemble the replies from the sub-messages, into a single outgoing message from
the [Splitter]. See the defaults described below in _[What the Splitter returns|#WhattheSplitterreturns]_.
From *Camel 2.12* onwards you can also use a POJO as the {{AggregationStrategy}}, see the
[Aggregate|Aggregator2] page for more details. |
| {{strategyMethodName}} | | *Camel 2.12:* This option can be used to explicit declare the
method name to use, when using POJOs as the {{AggregationStrategy}}. See the [Aggregate|Aggregator2]
page for more details. |
| {{strategyMethodAllowNull}} | {{false}} | *Camel 2.12:* If this option is {{false}} then
the aggregate method is not used for the very first splitted message. If this option is {{true}}
then {{null}} values is used as the {{oldExchange}} (for the very first message splitted),
when using POJOs as the {{AggregationStrategy}}. See the [Aggregate|Aggregator2] page for
more details. |
| {{parallelProcessing}} | {{false}} | If enabled then processing the sub-messages occurs
concurrently. Note the caller thread will still wait until all sub-messages has been fully
processed, before it continues. |<span class="diff-html-added" id="added-diff-0" style="font-size:
100%; background-color: #ddfade;">&nbsp;</span>
<span class="diff-html-added" id="added-diff-1" style="font-size: 100%; background-color:
#ddfade;">|</span> <span class="diff-html-added" id="added-diff-2" style="font-size:
100%; background-color: #ddfade;">{{parallelAggregate}} </span>| {{<span class="diff-html-added"
id="added-diff-3" style="font-size: 100%; background-color: #ddfade;">false}} | *Camel
2.14:* If enabled then the {{aggregate}} method on {{AggregationStrategy}} can be called concurrently.
Notice that this would require the implementation of {{AggregationStrategy}} to be implemented
as thread-safe. By default this is {{false}} meaning that Camel synchronizes the call to the
{{aggregate}} method. Though in some use-cases this can be used to archive higher performance
when the {{AggregationStrategy}} is implemented as thread-safe. |
| {{</span>executorServiceRef}} | | Refers to a custom [Thread Pool|Threading Model]
to be used for parallel processing. Notice if you set this option, then parallel processing
is automatically implied, and you do not have to enable that option as well. |
| {{stopOnException}} | {{false}} | *Camel 2.2:* Whether or not to stop continue processing
immediately when an exception occurred. If disable, then Camel continue splitting and process
the sub-messages regardless if one of them failed. You can deal with exceptions in the [AggregationStrategy|http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/processor/aggregate/AggregationStrategy.html]
class where you have full control how to handle that. |
| {{streaming}} | {{false}} | If enabled then Camel will split in a streaming fashion, which
means it will split the input message in chunks. This reduces the memory overhead. For example
if you split big messages its recommended to enable streaming. If streaming is enabled then
the sub-message replies will be aggregated out-of-order, eg in the order they come back. If
disabled, Camel will process sub-message replies in the same order as they where splitted.
|
| {{timeout}} | | *Camel 2.5:* Sets a total timeout specified in millis. If the [Recipient
List] hasn't been able to split and process all replies within the given timeframe, then the
timeout triggers and the [Splitter] breaks out and continues. Notice if you provide a [TimeoutAwareAggregationStrategy|http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/processor/aggregate/TimeoutAwareAggregationStrategy.html]
then the {{timeout}} method is invoked before breaking out. If the timeout is reached with
running tasks still remaining, certain tasks for which it is difficult for Camel to shut down
in a graceful manner may continue to run.  So use this option with a bit of care.  We may
be able to improve this functionality in future Camel releases. |
| {{onPrepareRef}} | | *Camel 2.8:* Refers to a custom [Processor] to prepare the sub-message
of the [Exchange], before its processed. This allows you to do any custom logic, such as deep-cloning
the message payload if that's needed etc. |
| {{shareUnitOfWork}} | {{false}} | *Camel 2.8:* Whether the unit of work should be shared.
See further below for more details. |
