# 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="/app/generation/generators/generator-characteristics/consistency.md">Enabling 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="/app/generation/generators/generator-characteristics/linking-generators.md">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="/app/generation/generators/generator-characteristics/differential-privacy.md">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="/app/generation/generators/generator-characteristics/partitioning.md">Partitioning a column</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="/app/generation/generators/generator-characteristics/data-free-generators.md">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="/app/generation/generators/generator-characteristics/generators-uniqueness-constraints.md">Supporting 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="/app/generation/generators/generator-characteristics/generators-fpe.md">Format-preserving encryption (FPE)</a></td></tr></tbody></table>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
