Abstract: Methods and systems of a log engine for logging data operation in a file system is disclosed. The log engine includes a user interface module configured to receive a plurality of data operation logs that respectively record a data operation and a sequence ID corresponding to an order of the data operation being performed; and a shared log manager configured to provide an in queue configured to consolidate the plurality of data operation logs, and swap the plurality of data operation logs to an out queue with the plurality of data operation logs being ordered based on the sequence ID and saved in a shared log.

Abstract: The present disclosure relates to a method for managing cache data, an apparatus, a storage medium and an electronic device, the method includes: acquiring a remaining available space of a solid-state disk for storing cache data; upon the remaining available space being less than a first space threshold, determining a first target fragment group in the solid-state disk that has the greatest garbage proportion, each fragment group including a first number of fragments, and each fragment corresponding to a second number of contiguous logical address spaces in the solid-state disk; and purging the cache data in the first target fragment of the first target fragment group that has the greatest garbage proportion, with this method, the space utilization rate of the solid-state disk can be improved.
