Hi devs:
Using RocksDB, when key and namespace both have variable binary length, to
prevent [key, namespace] have equal binary number, we add key length and
namespace length after key and namespace respectively. Then the format is:
Keygroup – key -keyLength– namespace-namespaceLenth
Then what about we use a fixed length key and variable length namespace
and userkey. In current implement, I found the binary key format is as below:
Keygroup – key – namespace- userkey
Think about following situation, I think we may get the same value for
different [namespace, userkey]. or I get something wrong?
Keygroup key namespace userkey
