# Generator characteristics

When you consider which generator to use, it helps to be familiar with these generator characteristics.

## Configurable characteristics

<table data-view="cards"><thead><tr><th></th><th></th><th></th><th data-hidden data-card-target data-type="content-ref"></th></tr></thead><tbody><tr><td><strong>Consistency</strong></td><td>Map the same input values to the same output values across columns, tables, and databases.</td><td></td><td><a href="generator-characteristics/consistency">consistency</a></td></tr><tr><td><strong>Linking</strong></td><td>Identify columns that use the same generator and that are inter-dependent or correlated.</td><td></td><td><a href="generator-characteristics/linking-generators">linking-generators</a></td></tr><tr><td><strong>Differential privacy</strong></td><td>Ensures that the output does not reveal anything that is attributable to a specific member of the source data.</td><td></td><td><a href="generator-characteristics/differential-privacy">differential-privacy</a></td></tr><tr><td><strong>Column partitioning</strong></td><td>Base the value of a column on other related columns.</td><td></td><td><a href="generator-characteristics/partitioning">partitioning</a></td></tr></tbody></table>

## Other generator characteristics

These characteristics are either inherent to the generator or are based on the generator configuration.

<table data-view="cards"><thead><tr><th></th><th data-hidden data-card-target data-type="content-ref"></th></tr></thead><tbody><tr><td><strong>Data-free generators</strong><br><br>Indicates that the generator output is completely unrelated to the input.</td><td><a href="generator-characteristics/data-free-generators">data-free-generators</a></td></tr><tr><td><strong>Support for uniqueness constraints</strong><br><br>Some generators can be used on columns that have uniqueness constraints.</td><td><a href="generator-characteristics/generators-uniqueness-constraints">generators-uniqueness-constraints</a></td></tr><tr><td><strong>Format-preserving encryption (FPE)</strong><br><br>Encrypts data in such a way that the output is in the same format as the input.</td><td><a href="generator-characteristics/generators-fpe">generators-fpe</a></td></tr></tbody></table>

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.tonic.ai/app/generation/generators/generator-characteristics.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
