According to your HTTP request headers, selectors and rules are used to route your requests.

Selector is your first route, It is coarser grained, for example, at the module level.

Rule is your second route and what do you think your request should do,For example a method level in a module.

The selector and the rule match only once, and the match is returned. So the coarsest granularity should be sorted last.

All data is cached HashMap in the JVM So it's very fast.

When the user is managing changes in the background,

Soul dynamically updates the cache by listening to the zookeeper node.

This solution might rely on zookeeper,It may be replaced in the future issues

Node design for zookeeper zookeeper-node
