Work Advanced Deploy

The Coalesce Work Node is a versatile node that allows you to develop and deploy a Work table/view in Snowflake.

A Work node serves as an intermediary object and is commonly employed to store raw data before undergoing the crucial phases of transformation and loading into the main tables of the data warehouse.

This pivotal step ensures that the raw data is processed and structured effectively.

Work Advanced Deploy Node Configuration

The Work node type has two configuration groups:

• Node Properties

Altering the Work Tables and Transient Tables

A few types of column or table changes will result in an ALTER statement to modify the Persistent Table in the target environment, whether these changes are made individually or all together:

1. Changing table names
2. Dropping existing columns
3. Altering column data types
4. Adding new columns

The following stages are executed:

Stage	Description
Rename Table| Alter Column | Delete Column | Add Column | Edit table description	Alter table statement is executed to perform the alter operation

Work Advanced Deploy Recreating the Work Views

The subsequent deployment of Work node of materialization type view with changes in view definition, adding table description or renaming view results in deleting the existing view and recreating the view.

The following stages are executed:

Stage	Description

Work Advanced Deploy Drop and Recreate Work View/Table/Transient Table

Change	Stages Executed
View to table/transient table	Drop view Create or Replace Work table/transient table
