删除空对象，并可以以更有效的方式写入

def is_empty(obj):
    return not bool(obj)

data = [obj for obj in data if not is_empty(obj)]

data = list(filter(None, data))  # None作为过滤条件会自动去除空对象

batch_size = 100
for i in range(0, len(data), batch_size):
    batch = data[i:i + batch_size]
    # 执行写入操作
    write_to_database(batch)

import asyncio

async def write_batch(batch):
    # 异步写入操作
    await async_write_to_database(batch)

async def main():
    tasks = [write_batch(batch) for batch in data_batches]
    await asyncio.gather(*tasks)

asyncio.run(main())

def is_empty(obj):
    return not bool(obj)

def write_to_database(data):
    # 模拟数据库写入操作
    print(f"Writing {len(data)} items to database")

data = [{"id": 1}, {}, {"id": 3}, {}, {"id": 5}]
cleaned_data = [obj for obj in data if not is_empty(obj)]
write_to_database(cleaned_data)
