Re: Advice for Scheduler refactor.

So are we worried that there may be users who might be better off with the lower memory usage of the original implementation in addition to users such as Kevin for whom the faster implementation is better? Do we need the ability to choose between the implementations, or are the memory concerns min

Re: ActiveMQ 5.11 Dynamic Camel Route - Message Namespaces

Just getting back to this. So it's sounds like there's no resolution to this namespace issue. Short of removing name spaces from the messages or not using this feature. Thanks Mike -- View this message in context: http://activemq.2283324.n4.nabble.com/ActiveMQ-5-11-Dynamic-Camel-Route-Mess

Re: Advice for Scheduler refactor.

It can be.. but we’re only talking about 50k items. CHM should be fine around that order of items. The problem before was that there were multiple copy on write lists and queues (the Java collection kind) being scanned and purged again. One removed ActiveMQ works fine on large numbers of queues

Nice! I like what you've done. I originally used ConcurrenthashMap - but found it a bit of a hog, would be interested if you find different? > On 7 May 2015, at 19:58, Kevin Burton wrote: > >> On Thu, May 7, 2015 at 6:30 AM, Tim Bain wrote: >> >> I agree with your approach with the WeakRunn

Re: KahabDB compatibility issue between ActiveMQ 5.10 and ActiveMQ 5.11

Hi Tim, I don't have any specific idea as to what changed between the versions but i can point you to the part of code that does it. In my mulitKahaDB adapater configuration I have this entry:

Re: Queue Delete not working in 5.8

I tried adding the allowTempAutoCreationOnSend="true" setting to the config file but this actually somehow managed to double up the stale queues - I had 7 x DBSYNC-xxx queues before adding temp parameter - now I have 15. The stale queues (some of which will be weeks old) still do not get deleted.

Re: Advice for Scheduler refactor.

I agree with your approach with the WeakRunnable; I think that will achieve the goal without the performance hit of calling purge() after each cancellation. If you take on the synchronized keywords, you should consider whether we're worried about concurrent calls to doStart() and doStop(). That s

Re: “Usage" and other performance improvements by avoiding CopyOnWriteArrayList.

The other reason a List sometimes gets used is when you want to be able to arbitrarily order the elements. If you're using the natural ordering or can write a comparator, you can use a SortedSet, but if you need them to be reorderable, I don't know of a Collection that allows arbitrary ordering bu

Re: Queue Delete not working in 5.8

Is there any chance the queues that aren't getting GC'd are temp queues? http://activemq.2283324.n4.nabble.com/AMQ-5-5-remove-temporary-destination-td4498959.html indicates that to GC temp destinations you also need to set as well. Tim On May 7, 2015 5:38 AM, "waydena" wrote: > This section in

those changes look ok to me, as in they won't break anything and you have numbers that can make your case. Please splash in a patch or PR. On 2 May 2015 at 23:08, Kevin Burton wrote: > I’ve found 3 places where CopyOnWriteArrayList was being used and causing > significant performance impact O(N^2
