%% %% The storage model is a write-through model with both an ets and a dets %% table. Writes are done to both the ets and then the dets table, but reads %% are only done from the ets table. %% %% This approach also enables parallelism when using dets by returning the %% same dets table identifier when opening several files with the same %% physical location. %% %% NOTE: This could be implemented using a single dets table, as it is %% possible to open a dets file with the ram_file flag, but this %% would require periodical sync's to disk, and it would be hard %% to decide when such an operation should occur. %% 这个选择比较有趣! 声明:ITeye文章版权属于作者,受法律保护。没有作者书面许可不得转载。
