Subject Consistency question caused by Read_all and Write_one
Date Fri, 10 Dec 2010 20:49:40 GMT

I got a consistency problem in Cassandra.

Given a column family with a record:    Id   Name
                                                        1    David

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
Again what will Read_all("1") get?
