Abstract: A data writing method includes determining first data to be written into a circular storage queue; obtaining a global write pointer of the circular storage queue, where the circular storage queue includes a plurality of storage areas, each storage area includes a plurality of subareas, and the global write pointer points to a first storage area of the plurality of storage areas; obtaining a first write pointer of the first storage area, and determining a size of allocated space in the first storage area based on the first write pointer of the first storage area; if the size of the allocated space in the first storage area is less than a size of space of the first storage area, performing an FAA operation on the first storage area, to allocate a first subarea in the first storage area; and writing the first data into the first subarea.
