Description
Coalesce Base Node Types Package
The Coalesce Base Node Types Package includes:
Work
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 Node Configuration
The Work node type has two configuration groups:
Work Node Properties
There are four configs within the Node Properties group.
- Storage Location: Storage Location where the WORK will be created.
- Node Type: Name of template used to create node objects.
- Description: A description of the node's purpose.
- Deploy Enabled:
- If TRUE the node will be deployed / redeployed when changes are detected.
- If FALSE the node will not be deployed or will be dropped during redeployment.
Work Options
Your available options will change depending on table or view.
Create As Table
- Multi Source: True / False toggle that is Coalesce implementation of SQL UNIONs.
- True - Multiple sources can be combined in a single node. The sources are combined using the option specified in the Multi Source Strategy.
- UNION - Combines with duplicate elimination.
- UNION ALL - Combines without duplicate elimination.
- INSERT - Runs an individual insert query for each source.
- False - Single source node or multiple sources combined using a join.
- True - Multiple sources can be combined in a single node. The sources are combined using the option specified in the Multi Source Strategy.
- Truncate Before: True / False toggle that determines whether or not a table is overwritten each time a task executes.
- True - INSERT OVERWRITE is used to overwrite existing data with new data loaded by task
- False - INSERT is used to append new data into target table
- Enable tests:
- Distinct: True/False toggle that determines whether to add DISTINCT to SQL Query.
- True - Group by All is invisible. DISTINCT data is chosen for processing

Work Joins
Join conditions and other clauses can be specified in the join space next to mapping of columns in the UI.
📘 Specify Group by and Order by Clauses
You should specify group by and order by clauses in this space if you are not opting for the group by all and order by provided in OPTIONS config.
Work Deployment
Work Initial Deployment
When deployed for the first time into an environment the Work node of materialization type table will execute the below stage:
Create Work Table This will execute a CREATE OR REPLACE statement and create a table in the target environment.
When deployed for the first time into an environment the Work node of materialization type view will execute the below stage:
Create Work View This will execute a CREATE OR REPLACE statement and create a view in the target environment.
Work Redeployment
After the WORK node with materialization type table has been deployed for the first time into a target environment, subsequent deployments may result in either altering the WORK Table or recreating the WORK table.
Altering the Work Tables
There are few column or table changes like Change in table name,Dropping existing column, Alter Column data type,Adding a new column if made in isolation or all-together will result in an ALTER statement to modify the Work Table in the target environment.
The following stages are executed:
- Clone Table: Creates an internal table.
- Rename Table| Alter Column | Delete Column | Add Column| Edit table description |: Alter table statement is executed to perform the alter operation.
- Swap cloned Table: Upon successful completion of all updates, the clone replaces the main table ensuring that no data is lost.
- Delete Table: Drops the internal table.
Recreating the Work tables
If any changes like change in join clause,adding transformations,change in configs like adding distinct,group by or orderby ,the Work Table will be recreated by running a CREATE OR REPLACE statement.
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:
- Delete View
- Create View
Work Undeployment
If a Work Node of materialization type table is deleted from a Workspace, that Workspace is committed to Git and that commit deployed to a higher level environment then the WorkTable in the target environment will be dropped.
This is executed in two stages:
- Delete Table: Coalesce Internal table is dropped.
- Delete Table: Target table in Snowflake is dropped.
If a Work Node of materialization type view is deleted from a Workspace, that Workspace is committed to Git and that commit deployed to a higher level environment then the WorkView in the target environment will be dropped.
The stage executed:
Delete View: Drops the existing Work view from target environment.
Persistent Stage
The Coalesce Persistent Stage Nodes element, serving as an intermediary object, is frequently utilized to maintain data persistence across multiple execution cycles.
It plays a crucial role in tracking the historical changes of columns linked to business keys.
This functionality is particularly beneficial when the objective is to retain raw data for prolonged durations.
