### Column Distribution Specifications ###
 
columnspec:
  - name: domain
    size: gaussian(5..100)       #domain names are relatively short
    population: uniform(1..10M)  #10M possible domains to pick from

  - name: published_date
    cluster: fixed(1000)         #under each domain we will have max 1000 posts

  - name: url
    size: uniform(30..300)       

  - name: title                  #titles shouldn't go beyond 200 chars
    size: gaussian(10..200)

  - name: author

### Batch Ratio Distribution Specifications ###

insert:
  partitions: fixed(1)            # Our partition key is the domain so only insert one per batch

  select:    fixed(1)/1000        # We have 1000 posts per domain so 1/1000 will allow 1 post per batch

  batchtype: UNLOGGED             # Unlogged batches
