Distributed high-speed storage method based on key value model, document model and graph model data

The invention relates to a distributed high-speed storage method based on key values, documents and graph data, and the method comprises the steps of obtaining the key values, the documents and the graph data from a database or other data sources; performing distributed management and data partitioning on data, which comprises the steps that the data are stored in a memory, and if a query and calculation request is received, an application program queries the data from the memory and carries out calculation in the memory; and if the original management node leaves the cluster, setting the nodewhich is firstly added into the cluster before the original management node is added into the cluster as a new management node, broadcasting the new management node, carrying out data migration and partition table updating, and if a common node is newly added into or leaves the cluster, broadcasting the management node, and carrying out data migration and partition table updating.
