Question

我在配置烧瓶中的池大小时遇到问题。每隔10到20个来自前端的请求，服务器就会抛出sqlalchemy.exc.TimeoutError：大小为x的队列池限制达到溢出y达到错误，连接超时。代码如下。我怀疑问题出在基类上，但是我不确定，我无法自行解决问题。帮助非常有用。 Thx（关于初始化db和创建模型，没有db.py或models.py或类似的东西）

app.py

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'oracle+cx_oracle://username:password*@host/sid?encoding=UTF-8'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
app.config['SQLALCHEMY_POOL_SIZE'] = 15
app.config['SECRET_KEY'] = 'secret_key'
ma = Marshmallow(app)
CORS(app)
api.init_app(app)
db = SQLAlchemy(app)
jwt = JWTManager(app)

Base = automap_base()
Base.prepare(db.engine, reflect=True)

model_name = Base.classes.table_name
model_name = Base.classes.table_name
model_name = Base.classes.table_name
model_name = Base.classes.table_name

api.py

from flask_restx import Namespace, Resource, fields
from flask import request, jsonify

api = Namespace('portfolio_overall', description='Porfolio_overall')

@api.route('/<product>/Portfolioinfo/slide_test')
@api.param('product', 'The product identifier')
class Main_Overall(Resource):
    def get(self, product):

        from app import model_name, db, ma

        query = db.session.query(table_name).filter(table_name.someattribute==somefilter)

烧瓶达到队列池限制
