lambdaquerywrapper使用limit

lambdaquerywrapper使用limit可以通过以下方式实现：

1. 使用.limit()方法设置查询结果的最大数量，例如：

from boto3.dynamodb.conditions import Key, Attr
from aws_lambda_powertools.utilities.data_classes import DynamoDBPaginator
from aws_lambda_powertools.utilities.typing import LambdaContext
from typing import List

def query_table(table_name: str, partition_key: str, partition_value: str, limit: int) -> List[dict]:
    paginator = DynamoDBPaginator(table_name)
    query_kwargs = {
        "KeyConditionExpression": Key(partition_key).eq(partition_value),
        "Limit": limit
    }
    return paginator.query(query_kwargs)

2. 使用.scan()方法设置查询结果的最大数量，例如：

from boto3.dynamodb.conditions import Key, Attr
from aws_lambda_powertools.utilities.data_classes import DynamoDBPaginator
from aws_lambda_powertools.utilities.typing import LambdaContext
from typing import List

def scan_table(table_name: str, limit: int) -> List[dict]:
    paginator = DynamoDBPaginator(table_name)
    scan_kwargs = {
        "Limit": limit
    }
    return paginator.scan(scan_kwargs)

以上两种方法都可以使用lambdaquerywrapper库进行封装，例如：

from lambdaquerywrapper import DynamoDBWrapper

def query_table(table_name: str, partition_key: str, partition_value: str, limit: int) -> List[dict]:
    wrapper = DynamoDBWrapper(table_name)
    query_kwargs = {
        "KeyConditionExpression": wrapper.eq(partition_key, partition_value),
        "Limit": limit
    }
    return wrapper.query(query_kwargs)

def scan_table(table_name: str, limit: int) -> List[dict]:
    wrapper = DynamoDBWrapper(table_name)
    scan_kwargs = {
        "Limit": limit
    }
    return wrapper.scan(scan_kwargs)
