Question 1

How does Sigma improve performance and optimize compute costs?

Accepted Answer

Alpha Query, Sigma's proprietary in-browser intelligent query engine, caches and reuses previous results, enabling instant local joins and aggregations, which leads to sub-second response times and lower query costs. Combined with partial evaluation, which processes only the necessary data, these features reduce processing time, resource usage, and cloud warehouse expenses, even when working with billions of rows.

Question 2

What is writeback and how does it support collaborative workflows?

Accepted Answer

Writeback in Sigma lets users input, edit, or upload data directly into a workbook and write it back to the cloud data warehouse. With input tables and custom actions, Sigma enables real-time collaboration by allowing teams to update data, submit approvals, or adjust forecasts within dashboards. This integration drives business processes like emailing results or updating Salesforce records, turning insights into action and eliminating siloed spreadsheets for a more efficient, collaborative workflow.

Question 3

What is Ask Sigma? How do I use natural language queries?

Accepted Answer

Ask Sigma lets you type plain-English questions—like "Show me quarterly revenue by region"—and instantly generates the precise live query and visualization. Behind the scenes, an LLM translates your request into SQL, then executes it on your warehouse. Ask Sigma also displays its chain-of-thought (filters, joins, formulas) so you can trust and refine results. It's the fastest way for non-technical users to get accurate, governed BI insights without writing code.

Question 4

How do I get support if I need help using Sigma?
