Hi, community
Now, The `db-discovery` module integrates MYSQL MGR and openGuass, they
get master-slave relation through timed task polling, and about job code are
duplicat. So we plan to strip job code out of
s`hardingsphere-db-discovery-provider` module, move it to
`shardingsphere-db-discovery-core` management.
`shardingsphere-db-discovery-provider` module is only provide master-slave
relation. In order to achieve the purpose mentioned before, we will adjust
`db-discovery` module api.
`Before adjustment` :
