Question

我正在使用cassandra python driver数据存储区的发行版。 mah codez ...

from cassandra.io.libevreactor import LibevConnection
from cassandra.cluster import Cluster
cluster = Cluster(['some ip addr'])
cluster.connection_class = LibevConnection

失败：

   session = cluster.connect('demodb')
   session.execute("INSERT INTO colFamName(attr1, attr2) VALUES ('123jkd', 'sdflkj')")
   session.execute("SELECT attr1 FROM colFamName")

通过：

   session = cluster.connect('demodb')
   session.execute("INSERT INTO colFamName(attr1, attr2) VALUES ('123jkd', 'sdflkj')")
   session.set_keyspace('demodb')
   session.execute("SELECT attr1 FROM colFamName")

错误：

  File "build/bdist.linux-x86_64/egg/cassandra/cluster.py", line 995, in execute
  File "build/bdist.linux-x86_64/egg/cassandra/cluster.py", line 2195, in result
cassandra.InvalidRequest: code=2200 [Invalid query] message="unconfigured columnfamily <my_columnfamily_name>"

只要我自上次session.execute调用后'重置'键空间，

连续的session.execute调用就会起作用。我不应该在每次session.execute调用之后重置它。

想法？（我已经在github上提交了一个问题，并在收到回复时更新）

连续执行调用（CQL）上未配置的columnfamily错误
