python查询天蓝色表的所有行 [英] python querying all rows of azure table

问题描述

我的azure表中有大约20000行.我想查询azure表中的所有行.但是由于某些天蓝色的限制，我只能得到1000行.

I have around 20000 rows in my azure table . I wanted to query all the rows in the azure table . But due to certain azure limitation i am getting only 1000 rows.

我的代码

from azure.storage import TableService
table_service = TableService(account_name='xxx', account_key='YYY')
i=0
tasks=table_service.query_entities('ValidOutputTable',"PartitionKey eq 'tasksSeattle'")
for task in tasks:
    i+=1
    print task.RowKey,task.DomainUrl,task.Status    
print i

我想从有效输出表中获取所有行.有没有办法

I want to get all the rows from the validoutputtable .Is there a way to do so

推荐答案

但是由于某些天蓝色的限制，我只能得到1000行.

But due to certain azure limitation i am getting only 1000 rows.

这是已记录的限制.对Azure表的每个查询请求将返回不超过1000行.如果有1000个以上的实体，表服务将返回一个延续令牌，必须使用该令牌来获取下一组实体(请参见此处的备注"部分:

This is a documented limitation. Each query request to Azure Table will return no more than 1000 rows. If there are more than 1000 entities, table service will return a continuation token that must be used to fetch next set of entities (See Remarks section here: http://msdn.microsoft.com/en-us/library/azure/dd179421.aspx)

请参阅示例代码以从表中获取所有实体:

Please see the sample code to fetch all entities from a table:

from azure import *
from azure.storage import TableService

table_service = TableService(account_name='xxx', account_key='yyy')
i=0
next_pk = None
next_rk = None
while True:
    entities=table_service.query_entities('Address',"PartitionKey eq 'Address'", next_partition_key = next_pk, next_row_key = next_rk, top=1000)
    i+=1
    for entity in entities:
        print(entity.AddressLine1)
    if hasattr(entities, 'x_ms_continuation'):
        x_ms_continuation = getattr(entities, 'x_ms_continuation')
        next_pk = x_ms_continuation['nextpartitionkey']
        next_rk = x_ms_continuation['nextrowkey']
    else:
        break;
