Metadata updating method and system, object node and storage medium

The invention provides a metadata updating method and system, an object node and a storage medium. The metadata updating method comprises the steps of obtaining to-be-updated metadata corresponding to object data; obtaining a preset number of metadata from the to-be-updated metadata; integrating the preset number of metadata into a metadata updating request; and sending the metadata updating request to the container node so as to update the metadata in the container node through the metadata updating request. The invention comprises that after to-be-updated metadata are obtained, a preset number of metadata in the to-be-updated metadata are integrated into a metadata request to update the metadata in a container node; the original mode of updating the metadata one by one is changed into a mode of updating the metadata one by one. The metadata updating efficiency can be improved, the pressure of a metadata updating system is reduced, and the request success rate is improved. 本申请提供了一种元数据的更新方法、系统、对象节点及存储介质，该元数据的
