Distributed integrity

0.2 The complete version realizes the unique distributed & Strongly consistent framework ——MatrixCube, Now you can use MatrixOne Build a small cluster （MatrixCube Please refer to the official document for details ）.MatrixCube Framework help MatrixOne The database kernel has gained the ability of distributed deployment , At the same time, for our AOE The engine implements three load balancing mechanisms ：

• Realize the balance of storage space of each node , To make efficient use of the storage resources of each node ;

• Of each node Raft-Group Leader The balance of , So as to achieve load balancing of read and write requests ;

• Each node Table Balance of data distribution , To achieve table level request balancing .
