摘要： Example control methods of hybrid storage are provided, which are applied to each HDD-type storage device and each SSD-type storage device in a storage system having one or more HDD-type storage devices and one or more SSD-type storage devices. Each HDD-type storage device in the storage system is connected to the SSD-type storage device. Each HDD-type storage device and each SSD-type storage device stores one or more data blocks respectively. Access information of each data block stored in a storage device is periodically acquired. A storage location of each data block in the storage system is adjusted according to the acquired access information of each data block. By using the technical solution of the present disclosure, the storage location of the data block is dynamically configured according to an access frequency so that advantages of different storage devices are fully utilized.

摘要： The present application discloses a data processing method and device. The method includes: receiving a data update request sent by a user; sending a log update instruction separately to a primary server and at least two secondary servers based on the data update request; and when it is determined that the log update operation is completed, sending a data storage instruction separately to the primary server and a first secondary server in the at least two secondary servers. When the data update request is received, the log update instruction can be sent to the primary server and the secondary servers, so that the primary server and the secondary servers perform a log update operation, and the data storage instruction is sent to the primary server and one of the secondary servers when it is determined that the log update operation is completed. When data in the secondary server is lost, the lost data can be restored by using the prestored log, so as to ensure data consistency between the primary server and the secondary server, and only the primary server and one of the secondary servers store the data updates, thereby effectively reducing resources needed for data storage.

摘要： One embodiment of the present invention provides a system for facilitating dynamic load-based merging. During operation, the system identifies incremental data in memory of a first computing device. The incremental data comprises update to reference data in a storage device in a second computing device. If the size of the incremental data becomes greater than a threshold, the system selects a first server group from a plurality of server groups. The second computing device belongs to this first server group. The system then migrates data access requests from the first server group to other server groups in the plurality of server groups and merges the incremental data from the memory of the first computing device to the storage device in the second computing device. The merging includes batch sequential disk writes to the storage device of the second computing device.
摘要翻译：本发明的一个实施例提供了一种用于促进基于动态负载的合并的系统。在操作期间，系统识别第一计算设备的存储器中的增量数据。增量数据包括对第二计算设备中的存储设备中的参考数据的更新。如果增量数据的大小变得大于阈值，则系统从多个服务器组中选择第一个服务器组。第二计算设备属于该第一服务器组。然后系统将来自第一服务器组的数据访问请求迁移到多个服务器组中的其他服务器组，并且将增量数据从第一计算设备的存储器合并到第二计算设备中的存储设备。合并包括对第二计算设备的存储设备的批量顺序磁盘写入。

摘要： The present application provides a method, system and apparatus for managing primary and secondary databases. The method includes: determining whether a lock held by a primary database expires, where the primary database and secondary databases share the lock; if determining that the lock held by the primary database has expired, determining whether a lock renewal request of the primary database is received; and if the lock renewal request of the primary database is not received, selecting one of the secondary databases as a new primary database, and controlling the primary database to be switched to a secondary database. According to the method, if the primary database does not send the lock renewal request before the lock held by the primary database expires, it is determined that the lock held by the primary database is invalid and the primary database cannot normally serve a user, so that a secondary database is selected as a new primary database, thereby improving a speed and accuracy of switching between primary and secondary databases.

摘要： The present application provides an adaptive resource allocation method and apparatus. The method includes: collecting statistics about a request time, an actual execution time, and a response time of each service statement during a time period; determining, based on the request time, a time segment of the time period to which each service statement belongs; and determining a type of each service statement, and adjusting resource quotas of different types of service statements in a same time segment of a next time period, based on the actual execution time and the response time of each service statement in each time segment. Based on the present application, a system can adaptively adjust a resource configuration ratio of different types of services in different time segments based on a service request type received during running time and load statuses of different types of service requests, to ensure stable running of a core service (for example, a transaction service) and fully use system resources.

摘要： The present application discloses a time-based node election method and apparatus. The method includes: configuring, by a host, a same voting time and a same vote counting time for all nodes; and sending time configuration information that carries the configured voting time and vote counting time to all the nodes, so that the nodes vote in the voting time, count the number of votes in the vote counting time, and elect a leader node according to a vote counting result. Campaign nodes synchronously perform the voting operation and the vote counting operation according to the same voting time and the same vote counting time that are configured by the host, thus overcoming the defect in the prior art that the timing of each node for voting and vote counting is uncertain, so that the efficiency of determining a leader node in a node election process is significantly improved.
