@ShooterIT Another concern is that on Kvrocks, `SCAN` return the cursor
"_hello" but actually if you want to iterate on next element, it requires a
number based cursor.
For example:
```
127.0.0.1:6666> set "hi there" v0
OK
127.0.0.1:6666> set "hello" v1
OK
127.0.0.1:6666> SCAN 0 MATCH hel* COUNT 10000
1) "_hello"
2) 1) "hello"
127.0.0.1:6666> SCAN 0 MATCH he* COUNT 10000
1) "_hello"
2) 1) "hello"
127.0.0.1:6666> SCAN 0 MATCH h* COUNT 10000
1) "_hi there"
2) 1) "hello"
2) "hi there"
127.0.0.1:6666> SCAN "_hi there" MATCH h* COUNT 10000
1) "0"
2) (empty array)
127.0.0.1:6666> SCAN "hi there" MATCH h* COUNT 10000
1) "0"
2) (empty array)
127.0.0.1:6666> SCAN 1 MATCH h* COUNT 10000
1) "_hi there"
2) 1) "hi there"
```
Note that `SCAN "_hi there" ...` returns "0".
