Data-migrator is a declarative DSL for table driven data transformations, set up as an open and extensive system. Use this to create data transformations for changing databases as a result of changing code, initial loads to datalakes (it contains a Kinesis provider)and more.

class Result(models.Model):
  id   = models.IntField(pos=0) # keep id
  uuid = models.UUIDField()     # generate new uuid4 field
  a    = models.StringField(pos=1, default='NO_NULL', max_length=5, nullable='NULL', replacement=lambda x:x.upper())
  b    = models.StringField(pos=2, name='my_b')
