Prevent tombstones creation

Question

I need to perform an insert to Cassandra table without creating tombstones for any column. I am using a query similar to this :

insert into my_table(col1,col2,col3

Answer 1

Assuming you are using prepared statements you can use the "unset" functionality that was introduced in Cassandra 2.2.0, which lets you use leave prepared statement variables without values and without creating tombstones on the server. It is supported in the Java driver 3.0.0 and other drivers.
