- Integrate with /BurstCommitFrequency (Snowflake version 2.8).
- Continuous integration (Integrate without /Burst) (Snowflake version 2.8).
- Action Transform /SoftDelete (Snowflake version 2.8).
- Bulk load requires a staging area (LocationProperties /StagingDirectoryHvr) (Snowflake version 2.8).

- Identity columns (Snowflake version 2.8).
Other Capabilities
HVR supports the following capabilities on Snowflake:
- Call database procedure dbproc during replication jobs (action AgentPlugin /DbProc) (Snowflake version 2.8).
- International table and column names where DBMS is not configured with UTF-8 encoding (Snowflake version 2.8).
- Treat DBMS table names and columns as case sensitive if configured (action LocationProperties /CaseSensitiveNames defined) (Snowflake version 2.8, since HVR 5.6.5/1).
HVR does not support the following capabilities on Snowflake:
