# Delete Snowflake warehouse

The **Delete Snowflake warehouse** job entry drops a virtual warehouse from your Snowflake environment.

Dropping unused virtual warehouses can help you keep your Snowflake environment organized.

When you drop a warehouse, Snowflake immediately halts processing of all SQL queries and statements, which stops consumption of additional credits. If you want to prevent in-progress actions from terminating, suspend processing first using [Stop Snowflake warehouse](/pdia-data-integration/pdi-job-entries-reference-overview/stop-snowflake-warehouse.md).

{% hint style="danger" %}
A dropped warehouse cannot be recovered. You can only recreate it.
{% endhint %}
