Method and device for dividing storage space of nodes

The embodiment of the invention discloses a method for dividing a storage space of nodes. One specific embodiment of the method comprises the following steps: according to the number of the data output nodes in the data output node group and the number of the data input nodes in the data input node group, the data output node group and the data input node group are divided into at least one nodegroup, and the node group comprises the data output nodes and the data input nodes; in response to the fact that the number of the data output nodes in the node group is not equal to the number of thedata input nodes, storage space division is conducted on the nodes of the type with the small number in the node group. According to the embodiment, storage space division of the data output node orthe data input node is facilitated. 本申请实施例公开了用于划分节点的存储空间的方法。该方法的一具体实施方式包括：根据数据输出节点组中的数据输出节点的数目和数据输入节点组中的数据输入节点的数目，将数据输出节点组和数据输入节点组划分成至少一个节点分组，其中，节点分组包括数据输出节点和数据输入节点；响应于节点分组中数据输出节点的数目与数据输入节点的数目不等，对节点分组中数目少的类型的节点进行存储空间划分。该实施方式有助于实
