## Rationale ## Detailed Changes ## Test Plan

**Description** Merge the implementation of the procedure storage with the storage storage implementation to prevent cases where the etcd key is not prefixed with the root path. **Proposal** Support persisting...

**Description** After #273 , EnableSchedule is not persisted in cluster options in meta storage(currently implementation is etcd). After the `ceresmeta-server` restarts, the `EnableSchedule` will not take effect. **Proposal** Persist `EnableSchedule`...

**Description** During dynamic scheduling, querying table routing will return empty routing information, which is easy to cause confusion. **Proposal** During dynamic scheduling, return error? **Additional context**

**Description** Do not return an error when dropping a table that exists in ceresmeta but does not exist in ceresdb. **Proposal** * `handle_drop_table_on_shard` in meta_event service support `if exists`. **Additional...

**Description** With the addition of the cluster scheduling module, the current cluster metadata management is somewhat confusing. **Proposal** - [x] Define the memory data structure corresponding to pb. - [x]...

**Description** Start and stop the cluster manager when the leader changes. **Proposal** - [x] When the leader changes, the cluster manage is needed to be started or stopped. - [...

**Describe this problem** `Create table` and `Drop table` need to use routing. But the current logic is using the management addr to create table. **Steps to reproduce** **Expected behavior** **Additional...
