Data transmission method, system and apparatus, and non-transitory readable storage medium and electronic device

A data transmission method, comprising:

• sending a data transmission request of a first transmission protocol to a data response device, wherein the data transmission request is configured to indicate that a transmission operation is to be performed on data in a first storage space of a data response device, and a second storage space is further deployed on the data response device, wherein the second storage space is configured to store partial data in the first storage space, and the data response device is configured to perform the transmission operation on the first storage space after performing data synchronization on the second storage space and the first storage space according to first protocol information of a second transmission protocol on the data response device in response to the data transmission request, wherein the second transmission protocol is configured to maintain data synchronization between the second storage space and the first storage space, and the first protocol information is configured to indicate a data synchronization situation between the second storage space and the first storage space, and the data response device is further configured to query a target storage state of the target data from a storage state of the second transmission protocol recorded on the data response device in response to target data of a storage location where the transmission operation is to be performed indicated by the data transmission request being stored in the second storage space, wherein the first protocol information comprises the storage state, and the storage state is configured to indicate a synchronization state of data stored in the second storage space;
• and synchronize the target data to the first storage space in response to the target storage state being a target state, wherein the target state is configured to indicate that the target data is modified but not synchronized;
• and
• receiving information returned by the data response device after performing the transmission operation on the first storage space.
