getUserPropertiesCount

int getUserPropertiesCount()

 User defined key-value pairs.
 If user_properties contain the reserved keys by RocketMQ,
 the send message request will be aborted with status `INVALID_ARGUMENT`.
 See below links for the reserved keys

map<string, string> user_properties = 2;

containsUserProperties

boolean containsUserProperties(String key)

 User defined key-value pairs.
 If user_properties contain the reserved keys by RocketMQ,
