- 问题的具体描述
使用nebula-python连接storage,python代码如下:
import sys
sys.path.insert(0, '../')
from nebula2.mclient import MetaCache
from nebula2.sclient.GraphStorageClient import GraphStorageClient
# 设置所有 Meta 服务地址
meta_cache = MetaCache([('172.26.209.114', 9559)],50000)
graph_storage_client = GraphStorageClient(meta_cache)
resp = graph_storage_client.scan_vertex(
space_name='basketballplayer',
tag_name='player')
while resp.has_next():
result = resp.next()
for vertex_data in result:
print(vertex_data)
resp = graph_storage_client.scan_edge(
space_name='basketballplayer',
edge_name='follow')
while resp.has_next():
result = resp.next()
for edge_data in result:
print(edge_data)
运行报错:
