**Description** In the current implementation, shards will start to be allocated when the number of nodes reaches the threshold, but only some shards are available for a period of time...
**Describe this problem** The leader node of CeresMeta will OOM when the CeresDB node restarts, and it will also fail when electing new leader. **Steps to reproduce** 1. Deploy version...
**Describe this problem** In the current implementation of CeresMeta, the scheduler's verification of shard version inconsistency will result in the shard being closed. However, due to the backward heartbeat information...
**Description** This is a sub-task of https://github.com/CeresDB/ceresdb/issues/597 **Proposal** Two points - When a ceresdb server first register with meta, it should return all databases back to it. - When receive...
