A key-value store and a file system are integrated together to provide improved operations. The key-value store can include a log engine, a hash engine, a sorting engine, and a garbage collection manager. The features of the key-value store can be configured to reduce the number of I/O operations involving the file system, thereby improving read efficiency, reducing write latency, and reducing write amplification issues inherent in the combined key-value store and file system.

Key-value store and file system

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.
