# Limitations and considerations

The following limitations apply when using the Snowflake target endpoint in a Replicate task:

## General limitations

* Replication of tables with backslashes in their names (for example, SPECIAL\\TABLE\N) is not supported.
* When Bulk Loading is set as the loading method, the **Transactional apply** [Change Processing mode](https://help.qlik.com/en-US/replicate/May2026/Content/Global_Common/Content/SharedEMReplicate/Customize%20Tasks/tasks_applychangtunestab.htm) is not supported.
* When using Snowpipe Streaming as the loading method, the following limitations apply:
  * As Snowpipe only supports INSERT operations, the Apply Changes replication option will not be available.
  * When the Store Changes replication option is enabled, changes can only be stored in Change tables, not in an Audit table.
  * The Batch optimized apply change processing mode is not supported.
  * Username and password authentication is not supported.
  * The XML subtype is not supported.
  * Stopping Store Changes replication during a transaction and resuming it after 30 days or more might cause duplicate records on target. Snowflake automatically deletes channels after 30 days.

## Additional limitations when using Google Cloud Storage staging
