Subject Re: Getting Consistency level TWO when it is requested LOCAL_ONE
Date Thu, 11 Apr 2019 09:21:28 GMT
Hi Jean,

I want to understand how you are setting the write consistency level as
LOCAL ONE. That is with every query you mentioning consistency level or you
have set the spring cassandra config with provided consistency level.
Like this:

The only possibility i see of such behavior is its getting overridden from
some where.
