hi

<gigerl>

hi forest

05:56

<gigerl>

o he quit already

13:57

<chirino_m>

rajdavies: wow that xindice stuff is kinda crap.. it does not seem to handle concurrency very well..

13:58

<chirino_m>

what a letdown.

13:59

<rajdavies>

chirino_m: I remember looking at it over a year ago - shame it hasn't got any better :(

13:59

<rajdavies>

chirino_m: there is a b-tree index implementation - in Kaha - but its very slow :(

14:00

<sbordet>

hi ! I've been asked how many connections can a broker sustain, say topic consumers; you guys have any rough figure, by chance ?

14:01

<rajdavies>

sbordet: depends on the platform - but 1000+

14:01

<sbordet>

rajdavies: that's enough :)

14:02

<sbordet>

thanks !

14:02

<rajdavies>

np!

14:08

<st3fan>

i'm still seeing negative QueueSize values in 5.0 with JMX :-(

14:09

<st3fan>

even if I call the ResetStatistics operation

14:18

<chirino_m>

rajdavies: you got any benchmark tests setup to compare your btree to the hash?

14:21

<rajdavies>

just run the test cases

14:21

<rajdavies>

for hash indexes

14:23

<rajdavies>

chirino_m: also I don't think the b-tree implementation works :(

14:23

<chirino_m>

so nothing to compare them?

14:23

<chirino_m>

ah too bad.

14:24

<chirino_m>

one day we should make kaha it's own module..

14:25

<rajdavies>

chirino_m: agreed!

14:26

<rajdavies>

chirino_m: though we'd need to make it recoverable

14:27

<chirino_m>

aye..

14:28

<chirino_m>

Just wondering if it was decoupled and we advertised it as a bdb killer if folks would come and help fix it..

14:28

<jstrachan>

agreed

14:29

<jstrachan>

wonder if hadoop has any good btrees? they must use some somewhere?

14:32

<chirino_m>

jstrachan: peeking right now..

14:49

<sbordet>

rajdavies: while browsing amq code, I found this (BrokerService#711):

14:49

<sbordet>

systemUsage.getTempUsage().setLimit(1024 * 1024 * 1024 * 100); // 10 Gb

14:50

<sbordet>

however, 1024 * 1024 * 1024 * 100 overflows int, so actually this seems equivalent to setLimit(0)

14:51

<sbordet>

should I raise a jira ?

14:59

<rajdavies>

sbordet: crikey! - yes plese!

15:00

<sbordet>

it's enough to add * 100L (note the L) to the multiplication :)

15:01

<sbordet>

well replace that is :)

15:01

<sbordet>

raising jira now...

15:02

<rajdavies>

thx!

15:02

<sbordet>

np

15:02

<sbordet>

rajdavies: one q: storeUsage setting is per broker, right ?

15:02

<rajdavies>

yep - correct

15:02

<sbordet>

thx !

15:09

<sbordet>

rajdavies: https://issues.apache.org/activemq/browse/AMQ-1858

15:10

<rajdavies>

thx!

15:21

<st3fan>

hmm i'm doing 200-300 messages per second

15:22

<st3fan>

i have a whole bunch of interesting exceptions in my activemq.log for 5.1.0 btw

15:22

<st3fan>

NPEs, but also things like PropertyNotFoundException and 'Failed to build body from bytes' .. should I report things like that?

15:29

<sbordet>

I am sending a JMS message from Ruby (using stomp) to a topic

15:30

<sbordet>

I receive the message in a Java application, but the said message is always a BytesMessage

15:31

<sbordet>

is there a way to have the java consumer to receive a TextMessage ?

15:37

<rajdavies>

yep - please send in a jira
