## 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.
