Abstract

Provided are a data storage method and device for a distributed database. The method comprises: a first node receiving a record insertion request, said request carrying a first record; the first node, according to a mapping relationship between a foreign key identifier and a storage node, determining a first storage node in which a first related record corresponding to the first record is located, wherein a primary key identifier of the first related record and the foreign key identifier of the first record are identical; the first node inserting the first record into a second node within the first storage node. The present method solves the technical problems in the prior art of low data insertion efficiency and slow updating speeds.

Description

technical field [0001] The embodiment of the present invention relates to the field of information technology, and relates to a data storage method and device for a distributed database. Background technique [0002] In distributed data storage, the front-end server partitions or shards the data in each data table in the database according to certain rules and then distributes and stores them on multiple different nodes. The data here can be in the data table Multiple records for each node, and the database instance running on each node manages the records assigned to the node. In order to ensure the reliability of the system, in a distributed system, at least one data backup is usually made on other nodes for each piece of data, that is, after the master node receives the data, it will save data on one or more nodes (slave nodes) Since the partitioning and backup methods are used to act on each data table independently, when performing a more complex association query for ...
