I am doing FilterExpression with boto3 library and looking for a username in a table that has 4 entries in that table. FilterExpression is returning only 1 record and LastEvaluationKey with unique_id in it. When I pass that unique_id to get more values for that user, I get different data set.
def lambda_handler(event,context):
username="john"
response = emp_info.scan(
FilterExpression=Attr('username').eq(username)
)
print response
and when I see response and pass the value of "LastEvaluationKey", I see a different data set for different user.
How can I get all rows for the user and not random data set? I can confirm that user has 4 records in dynamodb.
因此,如果我以递归方式将用户名和“LastEvaluatedKey”传递给函数,它将返回所有数据,然后通过链接,我可以获得完整列表。
