The invention discloses a dynamic consistency control method in a massive data environment, comprising the following steps of: (1) carrying out initialization work on an environment by a main thread; (2) starting to monitor a read-write request, which is sent by a client-side, by a service node; (3) when the service node receives a data read-write request task sent by the client-side, firstly reading an operation type of the request task; (4) reading a deviation type of the request task and reading a deviation value of the request task; comparing a read result with an existing threshold value and then putting the read result to the tail part of a corresponding array; and (5) returning back to the step (2) and continuously monitoring requests sent by the client-side. According to the dynamic consistency control method provided by the invention, the difficulty that an existing key assignment type database cannot be used by different applications due to the difference between consistency requirements of service data can be overcome. Therefore, a user only needs to care about indexes and values of operated data to the consistency and does not need to spend a great deal of efforts to redevelop one set of the key assignment type database which only meets own service requirements.
