I was asked this question today on the Cassandra mailing list:
I am considering migration my application Cassandra Java driver from 3.4 to 4.9. Are there breaking changes between 3.4 and 4.9 (I expect so to be honest but I want to get a feel of how much effort there might be).
I want to implement backward paging feature in my application. I can either implement it in the application like Alex Ott mentioned in [Stack Overflow] or I could migrate to 4.9. I am wondering which would be relatively easier.
