我有以下代碼將文檔插入到 MongoDB 中，問(wèn)題是它非常慢，因?yàn)槲覠o(wú)法對(duì)其進(jìn)行多處理器處理，并且考慮到我必須檢查插入的每個(gè)文檔是否已經(jīng)存在，我相信不可能使用批量-插入。我想知道是否有更快的方法來(lái)解決這個(gè)問(wèn)題。在進(jìn)行下面的分析后，我發(fā)現(xiàn)check record()和update_upstream()是兩個(gè)非常耗時(shí)的函數(shù)。因此優(yōu)化它們會(huì)提高整體速度。任何有關(guān)如何優(yōu)化以下內(nèi)容的意見(jiàn)都將受到高度贊賞。謝謝你！import osimport pymongofrom directory import Directoryfrom pymongo import ASCENDINGfrom pymongo import DESCENDINGfrom pymongo import MongoClientfrom storage_config import StorageConfigfrom tqdm import tqdmdir = Directory()def DB_collections(collection_type):    types = {'p': 'player_stats',             't': 'team_standings',             'f': 'fixture_stats',             'l': 'league_standings',             'pf': 'fixture_players_stats'}    return types.get(collection_type)class DB():    def __init__(self, league, season, func=None):        self.db_user = os.environ.get('DB_user')        self.db_pass = os.environ.get('DB_pass')        self.MONGODB_URL = f'mongodb+srv://{self.db_user}:{self.db_pass}@cluster0-mbqxj.mongodb.net/<dbname>?retryWrites=true&w=majority'        self.league = league        self.season = str(season)        self.client = MongoClient(self.MONGODB_URL)        self.DATABASE = self.client[self.league + self.season]        self.pool = multiprocessing.cpu_count()        self.playerfile = f'{self.league}_{self.season}_playerstats.json'        self.teamfile = f'{self.league}_{self.season}_team_standings.json'        self.fixturefile = f'{self.league}_{self.season}_fixturestats.json'        self.leaguefile = f'{self.league}_{self.season}_league_standings.json'        self.player_fixture = f'{self.league}_{self.season}_player_fixture.json'        self.func = func    def execute(self):        if self.func is not None:            return self.func(self)def import_json(file):    """Imports a json file in read mode        Args:            file(str): Name of file    """    return dir.load_json(file , StorageConfig.DB_DIR)
