10 Tips to Optimize your Sigma Workbooks
June 30, 2026An honest take on Sigma vs. Databricks AI/BI
Let me start with something that might seem unusual coming from a Sigma partner: Databricks AI/BI is genuinely impressive. If your team lives in Databricks notebooks, runs ML pipelines on Databricks compute, and stores everything in Unity Catalog, Genie Space feels like magic. You type a question in plain English, generate SQL against your Delta tables, and get an answer in seconds with no context switching, extract, or waiting on a BI developer. For data science and engineering teams who are already deep in the platform, it’s hard to argue with.
Here’s where I have to be straight with you: that’s not the case for most organizations, and the question of whether Databricks AI/BI is the right BI layer for your business is different from whether Databricks is the right data platform. Lots of teams conflate the two, and it’s a costly mistake.
At Maverick Data, we regularly work with both tools for migrations and development workstreams, where the BI team is living with a platform decision they did not make. Here is what we see when the conversation moves beyond the product demo and into how teams work.
Where Databricks AI/BI earns its stripes
Genie Space works, and within the right context, it works really well.
The Unity Catalog integration is the biggest advantage. If you’ve already invested in Unity Catalog for governance, access control, and lineage, Genie natively inherits that foundation. Row-level security also follows the user, which matters because most BI tools require teams to recreate those rules in a separate layer and keep them aligned over time. Genie avoids that extra maintenance.
The natural language experience is also better than it was a year ago. The “thinking steps” that now surface in each response show how the prompt was interpreted before the SQL runs, giving practitioners visibility into what the model is doing and helping build trust.
The integration story also stands up to technical scrutiny. If you want an orchestrator agent to route complex questions to Genie and then hand the results to an LLM for narrative generation, that’s supported. For engineering teams building agentic data products on a Databricks foundation, this architecture makes perfect sense.
One more win worth mentioning is that Genie Space improves on its own. Confidence voting, trusted assets, and usage-based knowledge extraction mean a well-maintained Space gets measurably sharper on recurring questions over time, largely without intervention. Sigma improves differently by steering its AI with verified metrics and giving admins a usage dashboard that surfaces where answers are weak. However, closing that loop requires a person to act on it. If you want an assistant that quietly self-tunes based on usage, that leans towards Databricks. If you want the data team to stay in control of what “correct” means, Sigma’s approach fits better. Both are defensible positions as long as you know which one you’re choosing.
Giving credit where it’s due: for ML-first teams and engineering-heavy orgs already all-in on Databricks, AI/BI is a legitimate BI offering.
Where it gets harder in practice
Genie Spaces are scoped. Each Space has its own knowledge store, set of SQL snippets, join relationships, and tuning. That’s fine when you have one Space per team. It becomes a problem when you have ten Spaces across ten business domains, each with a slightly different definition of “revenue,” “active customer,” or “churn.” There’s no single semantic layer that governs what those terms mean across Spaces because the knowledge isn’t shared. So you end up with access governed by Unity Catalog, but the business logic is spread across Spaces that were built, tuned, and maintained separately.
We’ve already seen how this plays out in practice. One team builds a Sales Genie Space and another team builds a Finance one. Six months later, the CFO is looking at two versions of the same metric that don’t match. This gets especially messy when RevOps and Finance both have legitimate ownership of revenue logic, but each team tunes its own space to the version of the business it’s responsible for explaining. The issue here isn’t bad data; it’s business logic defined twice, with slight differences, in two separate places that don’t know the other exists. Databricks has introduced metric views in Unity Catalog to address this, but they’re still in public preview, so adoption is early, and the tooling around them isn’t mature enough yet to call this solved.
The user experience still has a ceiling. Genie is better for business users than anything Databricks has shipped before, but “better than Databricks notebooks” is a low bar for non-technical users. This means the interface is conversational, which is great for ad hoc questions, but there’s limited support for structured, visual self-service. And building a reliable, aesthetically polished dashboard that a VP will trust for a board meeting is still harder than it should be.
The Space authoring burden is real. A Genie Space is only as good as the work you put into it up front, such as clean Delta tables, well-modeled views, properly configured compute, careful naming conventions, and curated SQL snippets. I recently read this summed up well: building a great Space in development is easy; making it reliable for enterprise business users requires engineering work, and that doesn’t go away just because the interface is conversational.
What Sigma gets right, and where it falls short
Sigma starts from a different design premise where the analyst is in control, and the warehouse is the source of truth. Queries are pushed down to the compute layer, and analysts work in a familiar spreadsheet-style interface with full SQL access underneath. For business users who live in spreadsheets, this lowers the adoption barrier quickly because the mental model is already familiar. The Sigma workbook gives business and technical users a single place to work from, where you get warehouse-scale data with the exploratory freedom of Excel, without any data-extraction risk.
Sigma’s AI layer is evolving fast. The agentic capabilities, actions, and the ability to build workflows that connect analysis to downstream systems are areas in which Sigma is investing heavily. If you’ve followed the roadmap, it’s clear the platform is moving toward AI-augmented workflows where the analyst stays in the driver’s seat rather than handing control to the model.
Another capability that rarely comes up in these comparisons, but probably should, is that Sigma closes the loop between insight and action in a way Databricks doesn’t. Most BI tools, Genie included, are read-only by design, so you see the answer, then the work leaves the platform and goes into a spreadsheet on nobody’s server, syncing with nothing, and is stale the moment anything changes upstream. Sigma’s Input Tables let users write data directly back to the warehouse via the same spreadsheet interface they already use, with validation, permissions, and an audit trail. Add actions and controls on top of that, and you’re not building a dashboard anymore; you’re building a governed AI application. Replicating that in Databricks is a custom build, whereas in Sigma it’s a feature.
That said, I’ll be honest about where Sigma asks more of you. Sigma’s governance is warehouse-native, meaning your governance discipline must exist upstream. If you don’t have a solid dbt semantic layer, well-modeled marts, and clean naming conventions before you get to Sigma, the tool will expose that gap. Metric consistency in Sigma depends on what you’ve built below it; that’s a deliberate architectural choice that teams need to understand going in.
Sigma is also not trying to be your ML platform, pipeline tool, or data catalog; it’s a BI and analytics layer. If you want a single platform that handles everything, Sigma isn’t that, and it doesn’t claim to be.
One thing that surprises people when they dig into the architecture is that Sigma’s runtime cost can look different once you model how users work inside the product. A lot of dashboard exploration can be answered from browser cache or in-browser calculation paths before Sigma sends more work back to the warehouse. When those lower-cost paths cannot answer the interaction, Sigma sends a fresh query. On Databricks, those warehouse queries may also benefit from SQL caching when they qualify. For high-concurrency dashboards with many interactive users, those details can change the cost picture, so it is worth modeling against actual usage before assuming Databricks AI/BI is the lower-cost option just because it is bundled.
What buyers are saying
When a client tells me they’re leaning toward Databricks AI/BI because it’s already in their stack, I hear a few different things underneath that statement.
Sometimes it’s a reasonable engineering-efficiency argument: we don’t want another vendor, and we already have Unity Catalog governance, so let’s keep it consolidated. That’s a legitimate position, and in the right context, one we might agree with.
Other times, it’s a budget conversation in disguise: Databricks bundles AI/BI with the platform, so the marginal cost looks low. That framing underweights the cost of semantic fragmentation, Space maintenance overhead, and the analyst productivity gap when users can’t get what they need without engineering help.
It also doesn’t account for the fact that Genie runs on Databricks’ own models, so if a better/ cheaper model ships, or your requirements change, you’re stuck waiting on Databricks to move.
Sigma lets you configure the model you want. That’s important as AI pricing continues to shift. Occasionally, it’s a platform evaluation that’s being decided by whoever already has the vendor relationship, without the business users or the BI team having a voice in it.
Other times, it’s a platform evaluation that’s being decided by whoever already has the vendor relationship, without the business users or the BI team having a real voice in it.
My honest take is this: Databricks has earned its stripes as a data platform. Its BI layer is still maturing, and the governance architecture around Genie Spaces introduces complexity at scale that teams routinely underestimate until they’re already past the point of easy correction.
Sigma is an analytics platform that does fewer things, but does those things very well. It puts the analyst and the business at the center of the experience rather than treating them as downstream consumers of a platform built for engineers.
The answer to the question “Which is the right tool for me?” depends on your team, stack, governance maturity, and user persona. At Maverick Data, we help organizations think through that decision every day, and we’re happy to do it without a predetermined outcome.
