I am going through the documentation of cassandra , esp Cassandra definitive guide. I come across the following statement
Note that in the case where no clustering columns are provided, each partition consists of a single row
Isn't it each partition will contain "Group of rows" irrespective of clustering column provided( ordering) or not clustering column provided ( no ordering) - but still partition is "Group of rows" . Please add your thoughts
When there are no clustering keys a partition can only hold a single row. This is because there is only one row for every unique primary key. A primary key is the partition key and clustering keys combined.
So if there is only a partition key there is only one row per partition. Any additional inserts with the same partition key will overwrite the previous value.
Got it. That makes sense as the primary key constitutes only partition key :-) . If the partition key is used along with clustering keys, this partition points to group of rows which further segregated based on clustering key
