Question

我想获取数据库的详细信息，或者我想说一下Cosmos DB中存在的所有数据库的吞吐量值，还想检查数据库是否处于活动状态？

是否有相同的API？否则，如何获取数据库的吞吐量和状态？

我已经遍历了Cosmos DB的文档，但是没有找到任何帮助。

I want to get the throughput value for all the databases present in the Cosmos DB.

Answer 1

使用Python SDK时，可以使用request_charge来获取它，

Python SDK中的CosmosClient对象（请参阅此快速入门关于其用法）公开了last_response_headers词典，映射基础HTTP API返回的所有标头的最后一个操作已执行。请求费用可在 x-ms-request-charge键。

response = client.ReadItem('dbs/database/colls/container/docs/itemId', { 'partitionKey': 'partitionKey' })
request_charge = client.last_response_headers['x-ms-request-charge']

Python Azure SDK（> = 4.0.0）的示例

from azure.cosmos import CosmosClient

class AzureHelper(object):

    def __init__(self, url, key):
        self.url = url
        self.key = key
        self._client = None
        self._keyspace = None

    def connect(self):
        self._client = CosmosClient(self.url, self.key)

    def get_list_keyspaces(self):
        result = []
        for db in self._client.list_databases():
            result.append(db['id'])
        return result

    def switch_keyspace(self, keyspace):
        self._keyspace = self._client.get_database_client(keyspace)

    def get_list_tables(self):
        result = []
        for table in self._keyspace.list_containers():
            result.append(table['id'])
        return result

    def get_throughput(self, table):
        container = self._keyspace.get_container_client(table)
        offer = container.read_offer()
        throughput = offer.properties['content']['offerThroughput']
        return throughput

if __name__ == '__main__':
    url = '<Cosmos DB URL, like https://testdb.cosmos.azure.com:443>'
    key = '<Primary Password>'
    az = AzureHelper(url, key)
    az.connect()
    for keyspace in az.get_list_keyspaces():
        az.switch_keyspace(keyspace)
        for table in az.get_list_tables():
            throughput = az.get_throughput(table)
            print(f'keyspace {keyspace}, table {table}, throughput {throughput}')
