If I don't set any read/write consistency level at all in my spring-data-cassandra project, what will be my consistency level for reads? What about writes?

See https://jira.spring.io/browse/DATACASS-145 & https://jira.spring.io/browse/DATACASS-146. I am working on this in branch https://github.com/spring-projects/spring-data-cassandra/tree/DATACASS-145. When DATACASS-145 is done, I can move on to DATACASS-146.
I don't think it's going to make it into 1.1.0; 1.1.1 is likely.
