mangsud saya, pernah nyobain gem reliable-msg? implementasinya cak.
saya pernah nyobain stompserver (ini gem juga nih), kalo pake storage
persistent misalkan dbm atau file, mesti error kalo dikonek consumer bareng
producer:
Subscribing to /queue/foo
Sending a message to /queue/foo: MESSAGE
destination:/queue/foo
persistent:true
LAGI NGETEST NIH..\ntest message #1

Disconnecting
kalo pake storage memory lancar jaya.

wah saya lagi cari implementasi MQ yg kelas UKM cak. di CPAN ada
PoCo::MessageQueue yg nampaknya memadai,
sebetulnya ada plus/minusnya lah dibandingkan dng stompserver.
dia aman dikonek bareng consumer/producer. tapi racunnya ya keluar juga,
terutama di situasi many producers/many consumers.
yg kelas kapal enterprise dan nampaknya mantab adalah openamq - reference
implementation dari AMQP. sayangnya.. belum ada interface ke
wireapi di ruby dan perl :-)
tapi penggemar ruby tdk perlu khawatir, berhubung ruby bakal disupport di
project apache qpid.
rgds,
Edwin.
