Original topic: TIDB可以跳过PD直接与TIKV保存数据, 不需要多节点一至性, 可以实现吗

The topology architecture is that TiDB directly corresponds to N TiKV instances. TiKV only implements sharded data storage and does not require distributed locks or similar mechanisms. This way, when creating a database or table, you can directly specify which TiKV to store it on. By discarding PD, TiDB only handles computation on the frontend.

Unavailable. A PD must be assigned tasks.

You can do without TiDB, but you cannot do without PD.

Without PD, there would be no place to record which KV stores your data. So, can you directly use RocksDB? :smile:

The status of PD is the brain.

I remember that it is possible to use raw TiKV.

PD must be used to record metadata and allocate tasks.
