Claus Ibsen commented on CAMEL-8640:
------------------------------------
Also I lowered the max limit to 10.000 as 100.000 is likely way to high anyway.
> BacklogTracer allocates 100k elements for an array even it is not enabled

> Key: CAMEL-8640
> URL: https://issues.apache.org/jira/browse/CAMEL-8640
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 2.15.1
> Reporter: Mateusz Nowakowski
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 2.16.0, 2.15.3
>
>
> By default each camel context has one BacklogTracer which is by default
> disabled.
> However BacklogTracer contains a queue with
> {code}
> public static final int MAX_BACKLOG_SIZE = 100 * 1000;
> private final Queue<DefaultBacklogTracerEventMessage> queue = new
> ArrayBlockingQueue<DefaultBacklogTracerEventMessage>(MAX_BACKLOG_SIZE);
> {code}
> The easiest way:
> is it possible to replace it with LinkedBlockingQueue(int capacity)?
> Ideally the object could be initialized only when it is enabled but it seems
> BacklogTracer is not fully encapsulated (the queue reference is maintained
> also outside BacklogTracer in BacklogTracerAdvice)
