# Structural differences and limitations with Snowflake

{% hint style="info" %}
**Required license:** Professional or Enterprise
{% endhint %}

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

Snowflake workspaces cannot use the following table modes:

* Incremental

## Generator limitations <a href="#snowflake-tonic-differences-generators" id="snowflake-tonic-differences-generators"></a>

Snowflake workspaces cannot use the following generators:

* Algebraic
* Array JSON Mask
* Array Regex Mask
* Cross Table Sum
* Current Date
* Event Timestamps
* Geo
* Sequential Integer

## Support for table filtering <a href="#snowflake-tonic-differences-subsetting" id="snowflake-tonic-differences-subsetting"></a>

Snowflake workspaces support both subsetting and table filtering.

Table filtering means that for tables that use the De-Identify table mode, you can provide a `WHERE` clause to filter the table. For details, go to [Using table filtering for data warehouses and Spark-based data connectors](/app/generation/subsetting/table-filtering.md).

## No upsert <a href="#snowflake-aws-tonic-differences-upsert" id="snowflake-aws-tonic-differences-upsert"></a>

Snowflake workspaces do not support upsert.

## No output to a container repository <a href="#snowflake-aws-tonic-limitations-containerization" id="snowflake-aws-tonic-limitations-containerization"></a>

For Snowflake workspaces, you cannot write the destination data to a container repository.

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/snowflake/snowflake-structural-differences-limitations.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.
