Capabilities for Snowflake

This section lists the Capabilities of Fivetran HVR when using 'Snowflake'. For more information about the pre-requisites, access privileges, and other configuration requirements, see Snowflake Requirements.

Capture

HVR does not support Capture changes from location on Snowflake.

Repository Database

HVR does not support Repository database on Snowflake.

Integrate

HVR supports the following capabilities on Snowflake:

• Integrate changes into location (Snowflake version 2.8).
• Burst integration (Integrate with parameter Method=BURST) (Snowflake version 2.8).
• Integrate with parameter BurstCommitFrequency (Snowflake version 2.8).
• Continuous integration (Integrate with parameter Method=CONTINUOUS) (Snowflake version 2.8).
• ColumnProperties with parameter SoftDelete (Snowflake version 2.8).
• Bulk load requires a staging area (location property Staging_Directory) (Snowflake version 2.8).
• Creation and update of HVR state tables (Snowflake version 2.8).

HVR does not support the following capabilities on Snowflake:

• Tables without a key and without TableProperties with NoDuplicateRows for continuous integration.
• Continuous integrate with parameter OnErrorSaveFailed.
• Disable/enable database triggers during integrate (with parameter NoTriggerFiring).
• Integrate with parameter DbProc.

Bi-directional Replication

HVR does not support Bi-directional Replication on Snowflake.

Refresh and Compare

HVR supports the following capabilities on Snowflake:

• hvrrefresh or hvrcompare from source location (Snowflake version 2.8).
• hvrrefresh into target location (Snowflake version 2.8).
• Isolated table hvrrefresh (option -i) into target location (Snowflake version 2.8).
• Row-wise hvrrefresh into target location (option -g) (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 (AgentPlugin with parameter 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 (location property Case_Sensitive_Names) (Snowflake version 2.8).
• Treat DBMS schema names as case sensitive if configured (location property Case_Sensitive_Names) (Snowflake version 2.8).

HVR does not support the following capabilities on Snowflake:

• Use distribution key for parallelizing changes within a table (ColumnProperties with parameter DistributionKey).
• Lossless binary float datatypes. No data loss when transporting float values (because base 2 fractions are never converted to base 10). The values for these datatypes, when selected back from the database, might be slightly different from the ones that were inserted. This leads to Compare differences..
