A data synchronization method for a multi-level associative storage architecture includes: receiving, by a master module, a request of an external write operation, writing data into a write buffer of the master module, and recording a digit sequence according to the write operation on the write buffer of the master module; flushing data from the write buffer to solid-state disk (SSD) files when a data amount in the write buffer of the master module reaches a threshold; recording, by the master module, a digit sequence for a flush operation; separately synchronizing, by the master module, the write operation and the flush operation to a slave module according to orders of digits in different digit sequences; and receiving, by the slave module, the synchronous write operation and synchronous flush operation, and separately synchronizing the data of the master module to corresponding locations of a local write buffer and local SSD files.

Data synchronization method and data synchronization system for multi-level associative storage architecture, and storage medium

A distributed data storage system and method are disclosed. The distributed data storage system includes: an interface machine process module; at least one service process module; and at least one storage module. The interface machine process module is configured to receive a storage request containing data to be stored from a storage requester and distribute the storage request to one of the at least one service process module; the service process module is configured to receive the storage request from the interface machine process module and assign a storage identifier for the date contained in the storage request; the at least one storage module is configured to store the data according to the storage identifier assigned by the service process module. The distributed data storage system and method of the present invention can provide stable, simple, highly efficient, and low cost mass data storage and read/write services for users.

Distributed data storage system and method

The present invention discloses a method and apparatus for storing node, pertaining to the field of the Internet communications. The method includes: receiving a write operation request and a node from a client; storing the node in a memory and setting the update time of the node as the time of receiving the node; and relocating one or more nodes from the memory to a file according to the update time of each of the nodes in the memory. The apparatus includes: a receiving module, a storage module, and a relocating module. The present invention can reduce the frequency of loading and relocating nodes to and from a memory, and improve performance of a server.

Method and apparatus for storing node

The invention discloses a method for storing data and a device of implementing the same. The method comprises receiving a request for storing data sent by a user and storing the data to an SSD according to the received request. The device comprises a request receiving module used to receive the request storing data and an SSD storage module used to store the data to an SSD according to the received request. The invention ensures consistency of data storage by storing data to an SSD according to the received request, thereby reducing data redundancy caused by using a cache layer to cache the data in the prior art. Additionally, the use of a single layer of an SSD to store data avoids the need of reloading data in the cache layer once a machine is power-down, thereby reducing the complexity of system design and the cost of operation and maintenance.
