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 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

  • Applying changes to binary data types is not supported.

  • Working in Unlimited LOB mode is not supported.
