#### Can I use other Key-Value storage engines with TiDB?

Yes. TiKV and TiDB support many popular standalone storage engines, such as GolevelDB and BoltDB. If the storage engine is a KV engine that supports transactions and it provides a client that meets the interface requirement of TiDB, then it can connect to TiDB.
Yes. In addition to TiKV, TiDB supports standalone storage engines such as UniStore and MockTiKV. Note that in later TiDB releases, MockTiKV might NO LONGER be supported.

To check all TiDB-supported storage engines, use the following command:

{{< copyable "shell-regular" >}}

```shell
./bin/tidb-server -h
```

The output is as follows:

```shell
Usage of ./bin/tidb-server:
-L string
log level: info, debug, warn, error, fatal (default "info")
-P string
tidb server port (default "4000")
-V print version information and exit (default false)
.........
-store string
registered store name, [tikv, mocktikv, unistore] (default "unistore")
......
```

#### In addition to the TiDB documentation, are there any other ways to acquire TiDB knowledge?
