Method and device for processing object data

The invention discloses a method and device for processing object data, which are applied to object-based data storage equipment. The method disclosed by the invention comprises the following steps of: loading object metadata into an internal memory in advance, wherein the metadata comprises metadata of each object block; when the object needs to be written in, judging whether the object metadata corresponding to an object identifier of the object exists in the object metadata in the internal memory or not; if so, deleting the object corresponding to the object identifier and writing in the object; otherwise, writing in the object, wherein under the condition that a quota space of a object data document is not exceeded, the object data document can store a plurality of the objects. With the adoption of the method and device for processing the object data, disclosed by the invention, the processing performance of the object data can be improved.
