I got a consistency problem in Cassandra.
Given a column family with a record: Id Name
There are three backups for this column family.
Assume there are two write operation happens issued by the same application by this order: write_one("1", "Dan") ; write_one("1", "Ken").
What will Read_all("1") get?
Assume the above two write operations happens exactly the same time in two applications,
Again what will Read_all("1") get?
