Description

When testing my schema on single-node cluster, I am getting the identical data for each stress-test run

I specify my cassandra-stress.yaml file
Table and column spec

table_definition: |
  CREATE TABLE files (
    id uuid PRIMARY KEY,
    data blob
  ) 

columnspec:
  - name: data
    size: UNIFORM(10..100)
    population: UNIFORM(1..100B)

But when query table rows after test, I am getting data as identical string in each row

Command to run the test

cassandra-stress user profile=..\cqlstress-example.yaml n=20 ops(insert=5) -rate threads=8

What I am doing wrong?
My wish is to have the data of variable length
