[TiDB Usage Environment] Testing
[TiDB Version] 7.0.0
[Reproduction Path] What operations were performed to encounter the issue
[Encountered Issue: Issue Phenomenon and Impact]
I have a few questions:
TiKV introduces the next-generation storage engine partition Raft KV. By allowing each data Region to have its own RocksDB instance, the storage capacity of the cluster can be expanded from TB level to PB level, providing more stable write latency and stronger scalability.
Usage Restrictions
Since this feature is experimental, there are currently the following limitations:
- TiDB Lightning, TiCDC, BR, Dumping, and other data import, synchronization, and backup tools are not supported.
- The tikv-ctl command-line management tool is not supported.
- It cannot be used simultaneously with TiFlash.
- It needs to be enabled when creating the cluster and cannot be enabled after the cluster is created.
- Does this mean that there will be many RocksDB instances (hundreds or thousands) on each TiKV?
- Can the region size be appropriately increased?
- Will the above tools be supported in the future?
- Will this feature be GA in 7.1 LTS, or is there an estimated version for GA?
