答复: query statement return empty
Using java/C# rewrite the test case, the results are consistency.
Is there any problem for the python driver?

Hi ALL
The result of “select * from t_test where id = 1” statement is not consistency,
Could you tell me why?
test case,
I = 0;
While I < 5:
result = cassandra_session.execute(“select ratio from t_test where id = 1”)
print result
testing result:
[Row(ratio=Decimal('0.000'))]
[]
[Row(ratio=Decimal('0.000'))]
[Row(ratio=Decimal('0.000'))]
[Row(ratio=Decimal('0.000'))]
Cassandra cluster:
My Cassandra version is 2.12,
the Cassandra cluster has 9 nodes.
The python driver version is 2.6
I have tested both the AsyncoreConnection and LibevConnection, the results are in consistency.
Thanks a lot.
Peter
