c# - 如何修改写关注级别？

Question

我有一个包含 100,000,000 个文档的集合，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);

如何将写入关注级别从 1(默认)更改为 0？

Answer 1

使用 WithWriteConcern MongoCollection 对象上的方法以获取新的 IMongoCollection 对象，该对象将使用提供的写入关注进行查询。

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