[jira] [Updated] (ROCKETMQ-136) Provide a handy message queue
selector for order message sharding
[ https://issues.apache.org/jira/browse/ROCKETMQ-136?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jaskey Lam updated ROCKETMQ-136:
--------------------------------
Description:
When order message is needed, users need to provide a message queue selector to make sure that the messages which has the same shading key should be sent to the same message queue.
Actually this is a very common scenario with a common solutions, say consistent hashing.
We should provide a handy selector for them to easily do that, what they only need to provide is a sharding key.
A consistent hash selector will meet most of the user's need.
