Embodiment Construction
[0051] see figure 1 , figure 2 and image 3 , the time series database cache management method based on access trend prediction, specifically includes the following steps:
[0052] (1) The system cache is divided into two parts: the regular cache and the predictive cache. The regular cache is managed by the conventional cache management algorithm. Data loading is carried out for forecasting of client data access trends.
[0053] Specifically, in addition to the regular data cache, a predictive cache is added. The size of the predictive cache can be set to one-third to one-half of the regular cache, and its structure is consistent with the regular data cache. The read and write of the two caches Unification is handled by the cache management module, which remains transparent to other modules of the time series database. The prediction cache is used to load the possible future access data predicted by the system.
[0054] (2) The server side calculates the characteristics ...
