          TiKV has two types of kv API(txn and raw), both of them can scan reversely,




          • Txn KV: reverse kv_scan is available from v2.1.0-beta,


          • Raw KV: reverse raw_scan is only available on master(30251412). Because it is an experimental feature.



          Please consider upgrade to TiKV v2.1-rc if you want reverse kv_scan.
