## No automatic sensitivity scans

For a Spark SDK workspace, Structural does not automatically run sensitivity scans. You must [run the sensitivity scan manually](/app/generation/identify-sensitive-data/running-the-structural-sensitivity-scan.md#sensitivity-scan-manual) or [set up scheduled sensitivity scans](/app/generation/identify-sensitive-data/running-the-structural-sensitivity-scan.md#sensitivity-scan-schedule).

## No workspace inheritance <a href="#spark-sdk-tonic-differences-workspace-inheritance" id="spark-sdk-tonic-differences-workspace-inheritance"></a>

Spark SDK workspaces do not support workspace inheritance.

## Table mode limitations <a href="#spark-sdk-tonic-differences-table-modes" id="spark-sdk-tonic-differences-table-modes"></a>

You can only assign the De-Identify or Truncate table modes.

For Truncate mode, the table is ignored completely. The table does not exist in the destination database.

Spark SDK workspaces do not support subsetting.

## No upsert <a href="#spark-sdk-tonic-differences-upsert" id="spark-sdk-tonic-differences-upsert"></a>

Spark SDK workspaces do not support upsert.

# 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 dynamically by asking a question.

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

```
GET https://docs.tonic.ai/app/setting-up-your-database/spark-sdk/spark-sdk-tonic-differences.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
