Description

If you give the cluster column name in mixed case then the batch size is always chosen as 1, for example:

columnspec:
  - name: creationdate
    size: fixed(10)
    population: seq(1..4000000)
  - name: UniqueSequenceNumber      # Note mixed case  
    cluster: uniform(100..200)

insert:
  partitions: fixed(1)              
  batchtype: UNLOGGED
  select: uniform(10..15)/200

Running this results in

Generating batches with [1..1] partitions and [1..1] rows (of [1..1] total rows in the partitions)

Changing the cluster column name to uniquesequencenumber gives the expected results:

Generating batches with [1..1] partitions and [5..15] rows (of [100..200] total rows in the partitions)
