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 Deployment

Work Advanced Deploy 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 Advanced Deploy Redeployment

After the WORK node with materialization type table/transient table/view 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 and Transient 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:

  • 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

Fact Advanced Deploy Initial Deployment

When deployed for the first time into an environment the Fact node of materialization type table will execute the below stage:

  • Create Fact 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 Fact node of materialization type view will execute the below stage:

  • Create Fact View: This will execute a CREATE OR REPLACE statement and create a view in the target environment.

Fact Advanced Deploy Redeployment

After the Fact node of materialization type table has been deployed for the first time into a target environment, subsequent deployments may result in either altering the Fact Table or recreating the Fact table.

Altering the Fact Tables/Transient 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 Fact Table in the target environment.

The following stages are executed:

  • Rename Table| Alter Column | Delete Column | Add Column | Edit table description: Alter table statement is executed to perform the alter operation.

Recreating the Fact Advanced Deploy Views

The subsequent deployment of Fact node of materialization type view with changes in view definition,adding table description or renaming view results recreating the view

The following stages are executed:

  • Create View

Fact Advanced Deploy Undeployment

If a Fact 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 Fact Table in the target environment will be dropped.

This is executed in stages:

  • Drop table/view

Drop and recreate Fact View/Table/Transient

When the materialization type of Fact node is changed from View to table/transient table,the following stages are executed:

  • Drop view
  • Create Fact table/transient table

When the materialization type of Fact node is changed from table/transient table to View,the following stages are executed:

  • Drop table/transient table
  • Create Fact view

When the materialization type of Fact node is changed from table to transient table or transient table to table, the following stages are executed:

  • Drop table/transient table
  • Create Fact table/transient table

📘 Materialization Type of Dimension node

When the materialization type of Dimension node is changed from table/transient table to View and use Override Create SQL for view creation,ensure that the below change is made in the stage function in Create SQL tab so that the order of deployment is maintained.

Factless Fact Advanced Deploy

The Coalesce Fact UDN is a versatile node that allows you to develop and deploy a Fact table in Snowflake.

A factless fact table is used to record events or situations that have no measures, and it has the same level of detail as the dimensions

Factless Fact Advanced Deploy Node Configuration

Factless Fact Advanced Deploy Node Properties

  • 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.

Factless Fact Advanced Deploy Options

Factless_adv_deploy

  • Create As:Provides option to choose materialization type.

    • Table
    • Transient 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.
    • False - Single source node or multiple sources combined using a join.
  • 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: Provides option to specify tests in Testing section to check the data quality.

  • 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
    • False- Group by All is visible
  • Group by All: True/False toggle that determines whether to add GROUP BY ALL to SQL Query.

    • True - DISTINCT is invisible. Data is grouped by all columns for processing
    • False- DISTINCT is visible
  • Order By : True/False toggle that determines whether to add “ORDER BY” to SQL Query along with the column and sort order

    • True -Sort column and sort order drop down are visible and are required to form order by clause
    • False-Sort column and sort order drop down are invisible
  • Pre-SQL: Any SQL to be executed as a predecessor to data insert operation can be mentioned here

  • Post-SQL:Any SQL to be executed post the data insert operation can be specified here

Factless Fact Advanced Deploy Joins

Join conditions and other clauses like where, qualify can be specified in the join space next to mapping of columns in the Coalesce app.
