Abstract
A method and a system for cache management in system interfacing to a cloud storage. The cache has two layers: the filter layer for tracing read access to the data blocks and the cache layer for keeping the actual data blocks. The layer two consists of two modules—a main cache and a boot cache. The boot cache is filled during the short period of time after the first file open operation. The boot cache also has a limit on the amount of data that can be put into the cache for the particular file. The filter layer detects continuous read access pattern and avoids caching data, if the data is read continuously beyond some limit.
