A uniform distribution gives every value in a specified range an equal chance of appearing. In cassandra-stress, it constrains generated data to realistic bounds instead of allowing arbitrary values. section 11.2.1
Constraining generated review data
Set date_bucket to uniform(0..240) to generate twenty years of monthly buckets. Similar ranges can constrain scores to 1–100, author-name sizes to 5–20 characters, and titles to 20–50 characters. section 11.2.1
