Description

In case of command

cassandra-stress user profile=abc.yaml ...

and yaml file:

table_definition: | 
  CREATE TABLE prftest1.process_data (
  id uuid,
  id2 uuid,
  data blob,
  PRIMARY KEY (id, id2)

columnspec: 
  - name: id 
    population: seq(1..10) 
  - name: id2 
    population: seq(1..10)
  - name: data 
    size: uniform(5..10) 
    population: seq(1..100)

the values for id2 (with type uuid) are all the same (not random). 

 

NOTE: in case of type bigint for id and id2, the values for id2 are random items. 

It seems as possible issue in case of uuid column type see attached picture
