Could we use ToStringBuilder in Commons Lang3 to build equal and hash
override method?
> 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: vongosling
> 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.
