Snowflake Component Release Notes

This page lists the main features added to the Snowflake Component.

Feature Highlights

Version 2.1.3

Minor improvements and fixed issues

This version contains some minor improvements and fixed issues, which can be found in the complete changelog.

Version 2.1.2

Support additional timestamp types

Snowflake Component supports timestamp_ltz and timestamp_tz types.

Version 2.1.1

Work tables as transients

To reduce the cost of storage, addition of the keyword 'transient' (transient tables) to the creation of temporary tables.

The use of temporary tables do not need to have safe-back.

A transient table in Snowflake exists until it is explicitly destroyed and is visible to any user with the appropriate privileges.

Version 2.1.0

External Storage Attribute

Snowflake Component already supports storing temporary files inside external locations such as Microsoft Azure Storage or Amazon S3.

The Snowflake Metadata has been improved on this point, to automatically provide the list of storage nodes available in the workspace which can be used as external storage.

This allows to have a quick list without having to search them on your workspace.

Version 2.0.2

Tool Warehouse Operation

Snowflake allows to start / suspend the warehouse containing data, which allows to optimize costs and start it only when needed.

A new Process Tool has been added to allow starting / stopping Snowflake warehouses in your Processes.

You can use this to, as an example, start your warehouse at the beginning of you Process, then perform all your operations and, finally, suspend it at the end.

A Snowflake Metadata Link must be defined on the tool.

Then, specify the name of the Warehouse and the operation such as RESUME or SUSPEND.

Change Data Capture (CDC)

Multiple improvements have been performed to homogenize the usage of Change Data Capture (CDC) in the various Components.

Parameters have been homogenized, so that all Templates should now have the same CDC Parameters, with the same support of features.

Multiple fixes have also been performed to correct CDC issues. Refer to the changelog for the exact list of changes.

Version 2.0.1

Sample Project

The component example project can now be imported directly in the "New" menu of the Project Explorer.
