The invention discloses a load balancing prediction method of a distributed database, and a predictive analyzer. The load balancing prediction method of the distributed database comprises the following steps: collecting a load index on each local data node to form training set data; initializing a multilayer circulation neural network model; extracting data in one time period from the training set data to serve as the input of the multilayer circulation neural network model, extracting the data in an equal time period after the data in one time period from the training set data to serve as the output of the multilayer circulation neural network model, and training the multilayer circulation neural network model; and extracting the data which is after the data in the equal time period and is in the same time period to serve as the input of the multilayer circulation neural network model, and predicting the load index of the local data node. Therefore, the load balancing prediction method of the distributed database and the predictive analyzer can more precisely describe and effectively predict the structure of load balancing data.
