WebSocket currently only supports the consumption of a single topic, which cannot satisfy users' consumption scenarios of multiple topics.
Supports consumption of multiple topics or pattern topics.
Currently, the topic name is specified through path for consumption, like:
/ws/v2/consumer/persistent/my-property/my-ns/my-topic/my-subscription
If we want to support subscribing multi-topics, adding parameters will be confusing. Therefore, add a new v3 request path as follows:
For consumption of pattern-topics:
/ws/v3/consumer/subscription?topicsPattern="a.*"
For consumption of multi-topics:
/ws/v3/consumer/subscription?topics="a,b,c"
