与获取Aerospike集合中记录总数相关的澄清?需要Lua脚本吗?

我想通过python获取Aerospike集合中的记录总数。 我猜,它是在 show sets -

aql> show sets
+-----------+------------------+----------------+-------------------+----------------+---------------------+--------------------------------------------+------------+
| n_objects | disable-eviction | set-enable-xdr | stop-writes-count | n-bytes-memory | ns_name             | set_name                                   | set-delete |
+
| 179       | "true"           | "use-default"  | 0                 | 0              | "namespace"         | "setName"                        | "false"    |

从我读到的内容来看,似乎只有通过Lua脚本才能实现- https://discuss.aerospike.com/t/fastest-way-to-count-records-returned-by-a-query/2379/4

有人能证实吗? 但是,我可以通过使用计数器变量通过迭代 select() 和上面的数字相符-

client = aerospike.client(config).connect()

scan = client.scan('namespace', 'set')

scan.select('PK','expiresIn','clientId','scopes','roles') 
scan.foreach(process_result)
print "Total aeroCount"
print aeroCount


def process_result((key, metadata, record)):
    global aeroCount
    aeroCount=aeroCount+1

更新

我试过运行命令 asinfo -v sets 首先在命令行上。它也给了我物品的数量,像这样-

ns=namespace:set=setName:objects=29949: .

不确定如何准确地从中获取对象对集的计数。这个命令是否符合python函数的命令?我试过了

client = aerospike.client(config).connect()
response = client.info_all("asinfo -v sets")

我犯了一个错误-

  File "Sandeepan-oauth_token_cache_complete_sanity_cp.py", line 89, in <module>
    response = client.info_all("asinfo -v sets")
AttributeError: 'aerospike.Client' object has no attribute 'info_all'
