Description#

  • None: Search all

  • KeysOnly: Search Key only. It cannot be used together with ValuesOnly, DeserializeValues, PickField0, and PickField1.

  • RemovePrefix: Similar to KeysOnly. It will filter to the first byte of Key, i.e., the prefix of Key. It cannot be used together with ValuesOnly

  • ValuesOnly: Search Value only. It cannot be used together with KeysOnly and RemovePrefix.

  • DeserializeValues: Search Value and then deserialize the Value.

  • PickField0: Search the first element of Value array. It must be used together with DeserializeValues, not with PickField1.

  • PickField1: Search the second element of Value array. It must be used together with DeserializeValues, not with PickField0.
