IDGenerator

Compatibility: text data
The IDGenerator is used to create an indexed ID column that you may be using as a primary key. When transforming the data, it removes the column. When reversing the the transform, it creates an indexed ID column starting at a specified counter, with any additional prefixes or suffixes you provide.
from rdt.transformers.text import IDGenerator
​
transformer = IDGenerator(prefix='ID_', starting_value=0, suffix='-synthetic')
Parameters
prefix: A string with the prefix to use for the counter. All generated IDs will have the prefix.
(default) None
Do not add a prefix
<string>
Add the prefix to every ID
starting_value: The starting value for the counter
(default) 0
Start the counter at 0.
<integer>
Use the integer as the starting value. This must be >=0.
suffix: A string with the suffix to use for the counter. All generated IDs will have the suffix.
(default) None
Do not add a suffix
<string>
Add the suffix to every ID
FAQs
Will the generated IDs always be unique?
Yes. The generated IDs start at the starting_value parameter, and always increment by 1 for each new ID. Since there is no maximum value, the transformer will create unique IDs. (This is useful for primary keys.)
Tip: Use the reset_randomization method to reset the counter back to the original starting_value.
When should I use this transformer?
The IDGenerator is useful for ID columns that do not have any mathematical meaning. This transformer is useful for columns that represent indexed IDs, such as a primary key column.
