STILL TOO MUCH DUCT TAPE IN DATA TRANSFORMATION, DBT LABS’ HANDY SAYS

Alex Woodie

Tristan Handy at the Coalesce conference in San Diego, October 23

While real progress has been made in streamlining some aspects of big data
analytics workflows, there is still too much duct tape keeping it all together,
according to Tristan Handy, the founder and CEO of dbt Labs, which today
unveiled a slew of enhancements to dbt Cloud at its annual user conference.

Dbt has emerged as one of the most popular tools for preparing data for
analytics. Instead of writing raw SQL code, data engineers write dbt’s syntax to
create models that define the data transformations that need to be performed,
while respecting dependencies up and down the stack. At runtime, a dbt user
calls one model or series of models to execute a transformation in a defined,
declarative manner. It’s DevOps discipline meets data engineering, or DataOps.

The DataOps approach of dbt has resonated with millions of workers who use dbt,
or analytyics engineers, as dbt Labs likes to call them. When data
transformations are coded in dbt, it brings other benefits, like fewer lines of
code, automated documentation, visual lineage, and pipeline break notifications.

However, even with these data benefits in hand, it doesn’t mean we have solved
all data problems, Handy says.

“The data industry has made real progress towards maturity over the past
decade,” Handy says in a press release. “But real problems persist. Siloed data.
Lack of trust. Too much ‘duct tape’ in our operational systems.”

Handy elaborated on his thoughts in a blog post last month.

“We can observe from dbt product instrumentation data that a large majority of
companies that transition to the cloud adopt at least some elements of a mature
analytics workflow–particularly related to data transformations. But what about
the other layers of the analytics stack?” he wrote.

There are sticking points in those other layers, he says. For instance, Handy
asks whether notebooks and dashboards are well-tested and have provable SLAs.
“Do your ingestion pipelines have clear versioning? Do they have processes to
roll back schema changes? Do they support multiple environments?”

“Can data consumers request support and declare incidents directly from within
the analytical systems they interact with?” he asks. “Do you have on-call
rotations? Do you have a well-defined incident management process? The answer to
these questions, for almost every company out there, is ‘no,’” he writes.

While it’s unlikely that any one company or product could supply all those
capabilities, the folks at dbt Labs are making a go out of filling the gaps and
ripping off that duct tape. To that end, dbt Labs today announced a series of
enhancements in dbt Cloud, its enterprise offering for analytics professionals.
The company says these enhancements represent the “One dbt” vision of creating a
single dbt experience across multiple data personas and data platforms as part
of what it calls the analytics development lifecycle, or ADLC.

The company today unveiled several enhancements to dbt Cloud that it says will
help customers build better data pipelines. That includes dbt Copilot that will
automate repetitive manual work around things like creating tests, writing
documentation, and creating semantic models. Dbt Labs is also building a chatbot
that lets users ask questions of their data using natural language.

Dbt Labs is building on the data mesh that it launched at last year’s Coalesce,
which allowed cross-project dbt references, with a new cross-platform mesh. The
new offering uses Apache Iceberg to create portable data tables that can be read
across different platforms. Benefits include the ability to centrally define and
maintain data governance standards, to see end-to-end lineage across various
data platforms, and find, reference, and re-use existing data assets instead of
rebuilding, dbt Labs says.

Dbt Cloud customers are also getting a new low-code, drag-and-drop environment
for building and exploring dbt models. The company says this new environment
(which is currently in beta) will allow a new group of less-technical users to
develop analytics code themselves.

It will be easier to catch bugs in dbt code before they go into production using
the new Advanced CI (continuous integration) offering. Dbt Labs says Advanced CI
will make it easier for users to compare code changes as part of the CI process
and catch any unexpected behavior before the new code is merged into production.
“This improves code quality and helps organizations optimize compute spend by
only materializing correct models,” the company says.

Other improvements dbt Labs is making to dbt Cloud include:

 * Data health tiles that can be embedded into any downstream app to provide
   real-time info about their data, including freshness and quality, directly in
   tools where users work;
 * Auto-exposures with Tableau, a new feature that automatically incorporates
   Tableau dashboards into dbt lineage, boosting data freshness;
 * Semantic layer integration with Power BI;
 * New supported adapters, including Teradata (preview) and AWS Athena (GA).
