Supporting a World-class Documentation Technique with Atlan
The Energetic Metadata Pioneers sequence options Atlan clients who’ve accomplished a radical analysis of the Energetic Metadata Administration market. Paying ahead what you’ve discovered to the following knowledge chief is the true spirit of the Atlan neighborhood! In order that they’re right here to share their hard-earned perspective on an evolving market, what makes up their trendy knowledge stack, modern use instances for metadata, and extra.
On this installment of the sequence, we meet Tina Wang, Analytics Engineering Supervisor at Tala, a digital monetary providers platform with eight million clients, named to Forbes’ FinTech 50 listing for eight consecutive years. She shares their two-year journey with Atlan, and the way their sturdy tradition of documentation helps their migration to a brand new, state-of-the-art knowledge platform.
This interview has been edited for brevity and readability.
Might you inform us a bit about your self, your background, and what drew you to Information & Analytics?
From the start, I’ve been very serious about enterprise, economics, and knowledge, and that’s why I selected to double main in Economics and Statistics at UCLA. I’ve been within the knowledge house ever since. My skilled background has been in start-ups, and in previous expertise, I’ve all the time been the primary particular person on the information crew, which incorporates organising all of the infrastructure, constructing experiences, discovering insights, and many communication with individuals. At Tala, I get to work with a crew to design and construct new knowledge infrastructure. I discover that work tremendous fascinating and funky, and that’s why I’ve stayed on this area.
Would you thoughts describing Tala, and the way your knowledge crew helps the group?
Tala is a FinTech firm. At Tala, we all know immediately’s monetary infrastructure doesn’t work for many of the world’s inhabitants. We’re making use of superior know-how and human creativity to unravel what legacy establishments can’t or received’t, with a view to unleash the financial energy of the World Majority.
The Analytics Engineering crew serves as a layer between back-end engineering groups and numerous Enterprise Analysts. We construct infrastructure, we clear up knowledge, we arrange duties, and we be sure that knowledge is straightforward to seek out and prepared for use. We’re right here to ensure knowledge is clear, dependable, and reusable, so analysts on groups like Advertising and marketing and Operations can deal with evaluation and producing insights.
What does your knowledge stack appear like?
We primarily use dbt to develop our infrastructure, Snowflake to curate, and Looker to visualise. It’s been nice that Atlan connects to all three, and helps our technique of documenting YAML recordsdata from dbt and robotically syncing them to Snowflake and Looker. We actually like that automation, the place the Analytics Engineering crew doesn’t want to enter Atlan to replace info, it simply flows by means of from dbt and our enterprise customers can use Atlan instantly as their knowledge dictionary.
Might you describe your journey with Atlan, thus far? Who’s getting worth from utilizing it?
We’ve been with Atlan for greater than two years, and I imagine we had been considered one of your earlier customers. It’s been very, very useful.
We began to construct a Presentation Layer (PL) with dbt one yr in the past, and beforehand to that, we used Atlan to doc all our previous infrastructure manually. Earlier than, documentation was inconsistent between groups and it was typically difficult to chase down what a desk or column meant.
Now, as we’re constructing this PL, our aim is to doc each single column and desk that’s uncovered to the top consumer, and Atlan has been fairly useful for us. It’s very straightforward to doc, and really simple for the enterprise customers. They’ll go to Atlan and seek for a desk or a column, they will even seek for the outline, saying one thing like, “Give me all of the columns which have individuals info.”
For the Analytics Engineering crew, we’re usually the curator for that documentation. After we construct tables, we sync with the service house owners who created the DB to grasp the schema, and after we construct columns we arrange them in a reader-friendly method and put it right into a dbt YAML file, which flows into Atlan. We additionally go into Atlan and add in Readmes, in the event that they’re wanted.
Enterprise customers don’t use dbt, and Atlan is the one manner for them to entry Snowflake documentation. They’ll go into Atlan and seek for a selected desk or column, can learn the documentation, and might discover out who the proprietor is. They’ll additionally go to the lineage web page to see how one desk is said to a different desk and what are the codes that generate the desk. One of the best factor about lineage is it’s totally automated. It has been very useful in knowledge exploration when somebody is just not accustomed to a brand new knowledge supply.
What’s subsequent for you and your crew? Something you’re enthusiastic about constructing?
We now have been wanting into the dbt semantic layer previously yr. It is going to assist additional centralize enterprise metric definitions and keep away from duplicated definitions amongst numerous evaluation groups within the firm. After we principally end our presentation layer, we are going to construct the dbt semantic layer on prime of the presentation layer to make reporting and visualizations extra seamless.
Do you’ve gotten any recommendation to share together with your friends from this expertise?
Doc. Positively doc.
In considered one of my earlier jobs, there was zero documentation on their database, however their database was very small. As the primary rent, I used to be a powerful advocate for documentation, so I went in to doc the entire thing, however that might stay in a Google spreadsheet, which isn’t actually sustainable for bigger organizations with tens of millions of tables.
Coming to Tala, I discovered there was a lot knowledge, it was difficult to navigate. That’s why we began the documentation course of earlier than we constructed the brand new infrastructure. We documented our previous infrastructure for a yr, which was not wasted time as a result of as we’re constructing the brand new infrastructure, it’s straightforward for us to refer again to the previous documentation.
So, I actually emphasize documentation. If you begin is the time and the place to actually centralize your data, so at any time when somebody leaves, the data stays, and it’s a lot simpler for brand new individuals to onboard. No person has to play guessing video games. It’s centralized, and there’s no query.
Typically totally different groups have totally different definitions for related phrases. And even in these instances, we’ll use the SQL to doc so we are able to say “That is the method that derives this definition of Revenue.”
You wish to go away little or no room for misinterpretation. That’s actually what I’d like to emphasise.
The rest you’d prefer to share?
I nonetheless have the spreadsheet from two years in the past after I appeared for documentation instruments. I did a number of market analysis, taking a look at 20 totally different distributors and each instrument I might discover. What was necessary to me was discovering a platform that might hook up with all of the instruments I used to be already utilizing, which had been dbt, Snowflake, and Looker, and that had a powerful assist crew. I knew that after we first onboarded, we’d have questions, and we might be organising a number of permissions and knowledge connections, and {that a} sturdy assist crew can be very useful.
I remembered after we first labored with the crew, everyone that I interacted with from Atlan was tremendous useful and really beneficiant with their time. Now, we’re just about working by ourselves, and I’m all the time proud that I discovered and selected Atlan.
