如何修改写入关注度？

Question

我有一个包含100,000,000个文档的集合，其中我每分钟都在执行更新。像这样：

var writeOptions = new BulkWriteOptions { IsOrdered = false };

// Applying several operations within the one request.
operationList.Add(new UpdateOneModel<JobInfoRecord>(Builders<JobInfoRecord>.Filter.Eq("_id", document.JobId),
                                 Builders<JobInfoRecord>.Update.Set("JobInfo", newInfo)));

await jobInfoDocuments.BulkWriteAsync(operationList, writeOptions);

如何将写入关注度从1（默认值）更改为0？

Answer 1

使用MongoCollection对象上的WithWriteConcern方法获取一个新的IMongoCollection对象，该对象将使用提供的写入问题进行查询。

 var jobInfoDocumentsCareless = jobInfoDocuments.WithWriteConcern(WriteConcern.Unacknowledged);
 await jobInfoDocumentsCareless.BulkWriteAsync(operationList, writeOptions);
