The present invention discloses a data processing method and device, and relates to the field of computer technology. A specific implementation of the method includes: the service of the main thread receives request data, and performs first data processing corresponding to the request data; when the request data is the first request data, the service of the main thread persists the result data obtained by the first data processing to the local storage device through the memory file queue component, and the first request data is the request data that needs to perform a first type of resource operation during the processing; after the background listener listens to the persisted result data, it performs the first type of resource operation according to the result data to perform a second data processing corresponding to the first request data, and the background listener is independent of the main thread service. This implementation method can fundamentally improve the overall Ops of the cluster, improve the optimization effect of the imbalance of resource access speed, does not require too much hardware resource investment, and the data is more secure.
