negative.code: 1. <<redis-table-id-generation-strategy, TABLE>>
  2. <<redis-sequence-id-generation-strategy, SEQUENCE>>
  
  Both strategies will operate in the keys starting with `Identifiers` containing the last value of the id. The difference
  between the two strategies is the name of the key containing the values.
  
  The `AUTO` strategy is the same as the <<redis-sequence-id-generation-strategy, SEQUENCE>> one.
  
  The next value is obtained using Redis' http://redis.io/commands/hincrby[HINCRBY] command
