Describe your core logic of this feature as list

[chengyouling]

Core logic:

If the current instance service_meta matched serviceMeta config or current thread traffic tag matched trafficTag config, current instance mark as gray instance, or is base instance.

1、produce message

If current instance is gray, during produce message, set trafficTags in the message property.

2、consume message

gray instance

Only consume contains current consumerGroupTag corresponding traffic tags message.

base instance

auto model:

First, exclude consumerGroupTag corresponding traffic tags message that set in excludeGroupTags, dynamically querying whether there are new gray consumer group consume message, if have, exclude corresponding traffic tags message.

base mode:

Exclude consumerGroupTag corresponding traffic tags message that set in excludeGroupTags, if excludeGroupTags not set, then consume all message.
