在每个for循环迭代中保存mongodb文档，而不是等待循环完成

Question

我想在每次迭代中创建一个新文档，而不是AS-IS，文件都在for循环完成所有迭代后存储。我必须在for循环中等待58.000个项目，直到它保存到数据库...

是不是可以告诉mongoose以某种方式在for循环的每次迭代后保存每个文档？

我在代码中引用的mongoose模式称为：PartCluster

const mongoose = require("mongoose");
const fuzzball = require("fuzzball");
const CompanyPart = require("../../models/parts");
const PartCluster = require("../../models/PartClusters");

mongoose.connect("mongodb://localhost:27017/autoMDM", {
  keepAlive: true,
  reconnectTries: Number.MAX_VALUE,
  useMongoClient: true
});

mongoose.Promise = global.Promise;

mongoose.connection.on("error", err => {
  console.error(`Mongoose connection error: ${err}`);
  process.exit(1);
});

CompanyPart.find({}, { partName: 1 }, (err, parts) => {
  var obj = {};
  for (var i = 0, len = parts.length; i < len; i++) {
    obj[parts[i]["partName"]] = parts[i];
  }
  parts = new Array();
  for (var key in obj) {
    parts.push(obj[key]);
  }
  createCluster(parts);
});

function createCluster(arrayOfParts) {
  let usedStrings = [];
  let clusterArray = [];
  len = arrayOfParts.length;
  for (var i = 0; i < arrayOfParts.length; i++) {
    let cluster = [];
    y = 1;
    if (usedStrings.includes(arrayOfParts[i].partName)) {
      continue;
    }
    console.log(`item: ${i}, partName: ${arrayOfParts[i].partName}`);
    for (var j = y; j < arrayOfParts.length; j++) {
      if (
        fuzzball.token_sort_ratio(
          arrayOfParts[i].partName,
          arrayOfParts[j].partName
        ) > "70"
      ) {
        if (
          arrayOfParts[i].partName.toLowerCase() !==
            arrayOfParts[j].partName.toLowerCase() &&
          !cluster.includes(arrayOfParts[j].partName) &&
          !usedStrings.includes(arrayOfParts[j].partName)
        ) {
          cluster.push(arrayOfParts[j].partName);
          usedStrings.push(arrayOfParts[j].partName);
        }
      }
    }
    if (cluster.length > 0) {
      let obj = {};
      obj.clusterName = arrayOfParts[i].partName;
      obj.partCluster = cluster.sort();
      const query = { clusterName: arrayOfParts[i].partName };
      const update = obj;
      const options = { upsert: true };
      PartCluster.findOneAndUpdate(query, update, options, (error, result) => {
        if (error) {
          console.log("Error when saving cluster: ", error);
        }
      });
    }
  }
}
