Using Calculations


Materialization lets you write Sigma Data Blocks back to your data warehouse as a table. The Data Blocks will be written to a table in your data warehouse on the schedule that you set. The table in the warehouse will be overwritten each time the materialization schedule runs.

Set Up Materialization

Only Admins can set up Materialization schedules.

  1. Set up Write Access.
  2. Go to the overview page of the Data Block you would like to materialize. SQL Blocks and Worksheet Blocks both have the option to materialize.
  3. Click the ‘Edit’ button in the upper right.
  4. Go to the Materialization Tab.
  5. Click ‘Create Schedule’.
  6. Set the schedule for when you would like your Data Block to materialize.

Which Data Blocks Can Be Materialized

All SQL Blocks can be materialized.

Only Worksheet Blocks that exclusively use Table Blocks, Inline SQL, and CSV Uploads as a source will have materialization available.

If parameters or system functions are used in the Data  Block, materialization will not be available.

Materialized Tables in Your Warehouse

Materialized tables exist in the schema designated when you set up Write Access. They are visible through your cloud data warehouse but are not intended to be used as source tables for other applications. They also will not show up in Sigma through the connection browser.

If changes are made to materialized tables in the database, it will result in unexpected behavior, results or query failures.

Deleting Materialized Tables

When a materialization schedule is deleted completely, Sigma will automatically remove the materialized table from the warehouse. It can take up to 24 hours for the table to be deleted.
