In an embodiment, a first region is set according to a preset condition, the first region is a blank region reserved for storing new data of a key-value type. An embodiment method includes: when the new data of the key-value type is to be stored in the first region, receiving a region split command; updating, according to the region split command, a state identifier of the first region and in a state table to an identifier indicating that a read/write service is no longer provided, splitting the first region into at least two second regions, updating state identifiers of the second regions in the state table to identifiers indicating that a read/write service can be provided; and recording, in a metadata table, storage location information of the second regions.

Method for splitting region in distributed database, region node, and system

A data storage method and apparatus, where the method includes obtaining a primary index of a data object, where a row identifier of the primary index includes at least one field, determining a row identifier of a secondary index of the data object, where the row identifier of the secondary index includes an index field and a field other than the index field in the at least one field of the row identifier of the primary index, and the index field is different from the first field in the at least one field of the row identifier of the primary index, generating the secondary index of the data object according to the row identifier of the secondary index, and storing the data object according to the primary index and the secondary index, thereby saving storage space.

Data storage method and apparatus

A method for updating a data table in a KeyValue database is provided. Raw data is received and formatted into a data updating file. An update timestamp is set for each column qualifier in each row of the data updating file. A data deleting file is generated. A delete timestamp is set for each row of the data deleting file. Each row of the data deleting file corresponds to one row of old data in the data table. Each row of the data deleting file includes a row key that is the same as the row key of the corresponding row of old data in the data table. The data updating file and the data deleting file are both imported into the data table. Consequently, timestamp is used to indicate the valid data in the data table. An apparatus configured to perform the method is also provided.

Method and apparatus for updating data table in keyvalue database

A method and device for acquiring a response message, a method and device for routing the response message, and a system for acquiring the response message and routing the response message are disclosed. The method includes steps that: a source node sends a service request message to a second group of nodes via a first group of DRA nodes; and the source node acquires the service response message returned by the destination node via the second group of DRA nodes.

Method and device for acquiring response message, method and device for routing response message, and system for acquiring response message and routing response message
