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

If you insert null values, Cassandra will create tombstones. If you know that col3 will be null, don't use it in your query.

insert into my_table(col1,col2) values(val1,val2)

I would suggest two really good articles on the subject

• Common Problems with Cassandra Tombstones
• About Deletes and Tombstones in Cassandra.
