Meta service of HoraeDB cluster.
**Description** The default cluster must be created when a ceresmeta cluster is created, but in some cases, such default cluster is not necessary and consumes some resources. **Proposal** Add an...
### Description Currently, another table creation is disallowed if it fails to create the table firstly, which is unfriendly for use. ### Proposal The reason to disallow the retry to...
**Describe this problem** When the CeresMeta cluster runs online for a long time, the `DefaultCluster` cannot be loaded normally, resulting in a `ClusterNotFound` error. **Steps to reproduce** Not sure, maybe...
**Description** At present, `BatchProcedure` controls the number of single-batch executions through `ProcedureExecutingBatchSize`, but this quantity control is implemented in `Scheduler` instead of` BatchProcedure`. We may need to divide a single...
**Description** In the current implementation, we do not check and filter duplicate procedures (such as creating exactly the same table, scheduling to open the same Shard) **Proposal** Avoid generating exactly...
**Description** We currently use a simple version of consistent hashing as the core algorithm of the scheduling strategy. It cannot guarantee the uniform distribution of tables and shards. We need...
**Description** Now, the ddl and operation fsm in procedure are not clearly, and the error messages of fsm are mixed together. **Proposal** - Sort out the state flow of ddl...
**Description** In the current implementation, we cannot guarantee that a table cannot be opened on multiple shards, maybe we need a mechanism similar to `ShardLock` to solve this problem **Proposal**...
**Description** We only support the limit of the main machine now, we need to support the flow limit of the standby machine. **Proposal** - support flow limiter persistence. - master-slave...
**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**
