Hi,
Is it possible to "aggregate" zero messages with aggregator?
Here is my case (simplified) tested with Camel 2.9.2
from("direct:from")
.split(body().tokenize("\n"))
.filter(body().isNotEqualTo(""))
.aggregate(constant(true), new
MyAggregationStrategy()).completionTimeout(1000)
.log(LoggingLevel.INFO, "compleated by
${header.CamelAggregatedCompletedBy}").stop();
I get a file, split it into multiple lines, filter all blank lines,
aggregate it back.
If the file is empty or contains only blanks the .log line will never be
executed.
Moreover if MyAggregationStrategy implements
TimeoutAwareAggregationStrategy the timeout() method is never called.
By the way my case is equal to splitting input into zero elements
(imagine the input file is empty).
What is the recommended approach to such scenarios?
Thank you!
