-----------------------------------
Summary: Support client to allocate message q in machine room
nearby priority
Key: ROCKETMQ-203
URL: https://issues.apache.org/jira/browse/ROCKETMQ-203
Project: Apache RocketMQ
Issue Type: New Feature
Reporter: Jaskey Lam
Assignee: vongosling
Attachments: AVLCB%1XMJ}T_YXP[OPF){T.png
As the picture shows, in multi-machine room acrtiture , the consumer may be
deployed in different IDC and so do the broker.
But the user may possiblly need to consumer message from its own IDC since it
is near and faster. But when problem occurs say all consumers in one IDC is
crashed, the messages can also be consumed by other consumers in other IDC.
This is a very important feature for many users, but currently, if the user
needs this feature, they must implement their own allocate strategy which is
not easy and error prone.
And, this feature should be be conflict to the existing allocate strategy that
means the user can still choose their better allocate strategy say AVERAGE or
AVERAGE_BY_CIRCLE, but nearby machine room will be supported easily too.
