Important

mongosh Method

This page documents a mongosh method. This is not the documentation for a language-specific driver, such as Node.js.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

cursor.objsLeftInBatch() returns the number of documents remaining in the current batch.返回当前批次中剩余的文档数。

The MongoDB instance returns response in batches. MongoDB实例分批返回响应。To retrieve all the documents from a cursor may require multiple batch responses from the MongoDB instance. 要从游标中检索所有文档，可能需要来自MongoDB实例的多个批处理响应。When there are no more documents remaining in the current batch, the cursor will retrieve another batch to get more documents until the cursor exhausts.当当前批次中没有更多文档时，游标将检索另一个批次以获取更多文档，直到游标用完为止。
