The invention discloses a data caching method applied to storage equipment, a control device of the storage equipment and the storage equipment. The storage equipment comprises a first cache (212) anda second cache (213). When the storage device monitors that a first data block is cached in the first cache (212) (S301), a first data block to be deleted is cached in the first cache (212) (S601), or the caching time of the first data block in the first cache (212) exceeds a threshold value (S801), obtaining feature information of the first data block, and then determining whether the first datablock is stored in the second cache (213) according to the feature information of the first data block; and if it is determined that the first data block is stored in the second cache (213) (S303, S603, S803), adjusting the level of elimination priority of the first data block in the second cache (213) (S304, S604, S804). By coordinating the data in the first cache (212) and the second cache (213) in the storage device, the response speed of the IO request is improved.

In an example embodiment, a demand signal management system is configured to coordinate data harmonization among a plurality of entities. The demand signal management system may obtain unharmonized data through third party entities. Global records based on internal master records and taxonomy information may be distributed to the entities. In some embodiments certain entities may have authority to create new global records. In other embodiments, some entities may have authority to approve proposed new global records. In still other embodiments, some entities may not have authority to create new global records. Unharmonzied data sent to the entities for harmonization in accordance with the global records. The entities may accept or reject the harmonization request. If accepted, the entity may return an updated global record, a proposed new global record, and / or a new global record depending on the unharmonized data, the global records and the entities' authority.

In one embodiment, a data reconciliation engine works with data store nodes included in a distributed data store system to ensure consistency between the data store nodes. In operation, the data reconciliation receives a different data snapshot from each of the data store nodes. In response, the data reconciliation engine generates one or more recommendations designed to resolve inconsistencies between the data snapshots. The data reconciliation engine then transmits each recommendation to a different data store node. Because the data reconciliation engine performs many of the resource-intensive operations included in the data reconciliation process, the resources of the data store nodes may focus primarily on processing client requests instead of performing data reconciliation operations.Consequently, unlike conventional data store node based reconciliation applications, the data reconciliation engine may process large volumes of data without unacceptably increasing the time requiredfor the distributed data store system to respond to client requests.

Methods and systems are presented for providing data consistency in a distributed data storage system using an eventual consistency model. The distributed data storage system may store data across multiple data servers. To process a request for writing a first data value for a data field, a first data server may generate, for the first data value, a first causality chain representing a data replacement history for the data field leading to the first data value. The first data server may insert the first data value without deleting pre-existing data values from the data field. To process a data read request, multiple data values corresponding to the data field may be retrieved. The first data server may then select one data value based on the causality chains associated with the multiple data values for responding to the data read request.
