Rich Zhang commented on ROCKETMQ-121: ------------------------------------- Cool. Eric, could you initiate a discussion in dev mail list? As far as I know, ActiveMQ also use JavaCC to implement this functionality. > Support message filtering based on SQL92 > ---------------------------------------- > > Key: ROCKETMQ-121 > URL: https://issues.apache.org/jira/browse/ROCKETMQ-121 > Project: Apache RocketMQ > Issue Type: Wish > Components: rocketmq-client, rocketmq-store > Reporter: yukon > Assignee: Rich Zhang > Priority: Minor > > So far, RocketMQ only support message filtering feature by `TAG`, but one > message only can own one tag, this is too limited to meet complex business > requirements. > So, we want to define and implement a reasonable filter language based on a > subset of the SQL 92 expression syntax to support customized message > filtering. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
