如何优化django-import-export？

from import_export.admin import ImportExportModelAdmin
from .models import YourModel

class YourModelAdmin(ImportExportModelAdmin):
    list_display = ('field1', 'field2')
    fields = ('field1', 'field2', 'field3')

admin.site.register(YourModel, YourModelAdmin)

from django.db import transaction

@transaction.atomic
def your_import_function():
    # 导入逻辑

from import_export.resources import ModelResource
from .models import YourModel

class YourModelResource(ModelResource):
    class Meta:
        model = YourModel
        batch_size = 1000  # 设置合适的批处理大小

# 安装并配置 Celery
from celery import shared_task

@shared_task
def export_data_task():
    # 导出逻辑

from django.core.cache import cache

def get_cached_data():
    data = cache.get('key')
    if data is None:
        data = YourModel.objects.all()
        cache.set('key', data, timeout=60*5)  # 缓存5分钟
    return data

from django.db import transaction

@transaction.atomic
def your_import_function():
    # 导入逻辑

class YourModelResource(ModelResource):
    class Meta:
        model = YourModel
        batch_size = 1000
