Postman: An Energetic Metadata Pioneer – Atlan


Unlocking Quick, Assured, Information-driven Selections with Atlan

The Energetic Metadata Pioneers collection options Atlan prospects who’ve accomplished an intensive analysis of the Energetic Metadata Administration market. Paying ahead what you’ve realized to the following information chief is the true spirit of the Atlan group! In order that they’re right here to share their hard-earned perspective on an evolving market, what makes up their trendy information stack, revolutionary use circumstances for metadata, and extra.

On this installment of the collection, we meet Prudhvi Vasa, Analytics Chief at Postman, who shares the historical past of Information & Analytics at Postman, how Atlan demystifies their trendy information stack, and greatest practices for measuring and speaking the affect of knowledge groups.

This interview has been edited for brevity and readability.


Would you thoughts introducing your self, and telling us the way you got here to work in Information & Analytics?

My analytics journey began proper out of faculty. My first job was at Mu Sigma. On the time, it was the world’s largest pure-play Enterprise Analytics Providers firm. I labored there for 2 years supporting a number one US retailer the place initiatives various from basic reporting to prediction fashions. Then, I went for my increased research right here in India, graduated from IIM Calcutta with my MBA, then labored for a 12 months with one of many largest firms in India.

As quickly as I completed one 12 months, I received a possibility with an e-commerce firm. I used to be interviewing for a product function with them they usually mentioned, “Hey, I feel you will have a knowledge background. Why don’t you come and lead Analytics?” My coronary heart was all the time in information, so for the following 5 years I used to be dealing with Information & Analytics for a corporation known as MySmartPrice, a value comparability web site.

5 years is a very long time, and that’s when my time with Postman started. I knew the founder from faculty and he reached out to say, “We’re rising, and we need to construct our information group.” It seemed like a really thrilling alternative, as I had by no means labored in a core expertise firm till then. I believed this could be a fantastic problem, and that’s how I joined Postman.

COVID hit earlier than I joined, and we had been all discovering distant work and learn how to alter to the brand new regular, however it labored out nicely in the long run. It’s been three and a half years now, and we grew the group from a group of 4 or 5 to virtually a 25-member group since.

Again at first, we had been operating considerably of a service mannequin. Now we’re correctly embedded throughout the group and we’ve an excellent information engineering group that owns the end-to-end motion of knowledge from ingestion, transformations, to reverse ETL. Most of it’s accomplished in-house. We don’t depend on a number of tooling for the sake of it. Then as soon as the engineers present the information help and the tooling, the analysts take over. 

The mission for our group is to allow each operate with the ability of knowledge and insights, rapidly and with confidence. Wherever any person wants information, we’re there and no matter we construct, we attempt to make it final eternally. We don’t need to run the identical question once more. We don’t need to reply the identical query once more. That’s our largest motto, and that’s why regardless that the corporate scales rather more than our group, we’re capable of help the corporate with out scaling linearly together with it. 

It’s been virtually 12 years for me on this trade, and I’m nonetheless excited to make issues higher each day.

May you describe Postman, and the way your group helps the group and mission?

Postman is a B2B SaaS firm. We’re the whole API Improvement Platform. Software program Builders and their groups use us to construct their APIs, collaborate on constructing their APIs, take a look at their APIs, and mock their APIs. Folks can uncover APIs and share APIs. With something associated to APIs, we would like individuals to return to Postman. We’ve been round since 2012, beginning as a aspect undertaking, and there was no trying again after that. 

As for the information group, from the beginning, our founders had a neat concept of how they needed to make use of information. At each level within the firm’s journey, I’m proud to say information performed a really pivotal function, answering essential questions on our goal market, the dimensions of our goal market, and the way many individuals we might attain. Information helped us worth the corporate, and after we launched new merchandise, we used information to know the precise utilization limits for every of the merchandise. There isn’t a single place I might consider the place information hasn’t made an affect.

For instance, we used to have paid plans within the occasion that somebody didn’t pay, we might look ahead to three hundred and sixty five days earlier than we wrote it off. However after we regarded on the information, we realized that after six months, no person returned to the product. So we had been ready for six extra months earlier than writing them off, and we determined to set it to 6 months. 

Or, let’s say we’ve a pricing replace. We use information to reply questions on how many individuals might be completely happy or sad about it, and what the overall affect is likely to be.

Probably the most impactful factor for our product is that we’ve analytics constructed round GitHub, and might perceive what persons are asking us to construct and the place persons are dealing with issues. Every single day, Product Managers get a report that tells them the place persons are dealing with issues, which tells them what to construct, what to unravel, and what to answer.

In the case of how information has been utilized in Postman, I might say that in the event you can take into consideration a method to make use of it, we’ve applied it.

The essential factor behind all that is we all the time ask in regards to the function of a request. For those who come to us and say “Hey, can I get this information?” then no person goes to answer you. We first want to know the evaluation affect of a request, and what persons are going to do with the information as soon as we’ve given it to them. That helps us truly reply the query, and helps them reply it higher, too. They could even notice they’re not asking the precise query.

So, we would like individuals to suppose earlier than they arrive to us, and we encourage that quite a bit. If we simply construct a mannequin and provides it to somebody, with out realizing what’s going to occur with it, a number of analysts might be disheartened to see their work go nowhere. Influence-driven Analytics is on the coronary heart of all the things we do.

What does your stack appear like?

Our information stack begins with ingestion, the place we’ve an in-house software known as Fulcrum constructed on high of AWS. We even have a software known as Hevo for third-party information. If we would like information from Linkedin, Twitter, or Fb, or from Salesforce or Google, we use Hevo as a result of we are able to’t sustain with updating our APIs to learn from 50 separate instruments.

We comply with ELT, so we ingest all uncooked information into Redshift, which is our information warehouse, and as soon as information is there, we use dbt as a metamorphosis layer. So analysts come and write their transformation logic inside dbt. 

After transformations, we’ve Looker, which is our BI software the place individuals can construct dashboards and question. In parallel to Looker, we even have Redash as one other querying software, so if engineers or individuals exterior of the group need to do some ad-hoc evaluation, we help that, too.

We even have Reverse ETL, which is once more home-grown on high of Fulcrum. We ship information again into locations like Salesforce or e mail advertising and marketing marketing campaign instruments. We additionally ship a number of information again to the product, cowl a number of suggestion engines, and the search engine inside the product. 

On high of all that, we’ve Atlan for information cataloging and information lineage.

May you describe Postman’s journey with Atlan, and who’s getting worth from utilizing it?

As Postman was rising, probably the most frequent questions we obtained had been “The place is that this information?” or “What does this information imply?” and it was taking a number of our analysts’ time to reply them. That is the rationale Atlan exists. Beginning with onboarding, we started by placing all of our definitions in Atlan. It was a one-stop resolution the place we might go to know what our information means.

In a while, we began utilizing information lineage, so if we realized one thing was damaged in our ingestion or transformation pipelines, we might use Atlan to determine what belongings had been impacted. We’re additionally utilizing lineage to find all of the personally identifiable data in our warehouse and decide whether or not we’re masking it accurately or not.

So far as personas, there are two that use Atlan closely, Information Analysts, who use it to find belongings and preserve definitions up-to-date, and Information Engineers, who use it for lineage and taking good care of PII. The third persona that we might see benefitting are all of the Software program Engineers who question with Redash, and we’re engaged on transferring individuals from Redash over to Atlan for that.

What’s subsequent for you and the group? Something you’re enthusiastic about constructing within the coming 12 months?

I used to be at dbt Coalesce a few months again and I used to be fascinated with this. We now have an essential pillar of our group known as DataOps, and we get day by day reviews on how our ingestions are going. 

We are able to perceive if there are anomalies like our quantity of knowledge growing, the time to ingest information, and if our transformation fashions are taking longer than anticipated. We are able to additionally perceive if we’ve any damaged content material in our dashboards. All of that is constructed in-house, and I noticed a number of new instruments coming as much as tackle it. So on one hand, I used to be proud we did that, and on the opposite, I used to be excited to attempt some new instruments.

We’ve additionally launched a caching layer as a result of we had been discovering Looker’s UI to be somewhat non-performant and we needed to enhance dashboard loading instances. This caching layer pre-loads a number of dashboards, so at any time when a shopper opens it, it’s simply accessible to them. I’m actually excited to maintain bringing down dashboard load instances each week, each month.

There’s additionally a number of LLMs which have arrived. To me, the largest drawback in information continues to be discovery. A number of us try to unravel it, not simply on an asset stage, however on a solution or perception stage. Sooner or later, what I hope for is a bot that may reply questions throughout the group, like “Why is my quantity happening?”. We’re attempting out two new instruments for this, however we’re additionally constructing one thing internally. 

It’s nonetheless very nascent, we don’t know whether or not will probably be profitable or not, however we need to enhance shoppers’ expertise with the information group by introducing one thing automated. A human could not have the ability to reply, but when I can prepare any person to reply after I’m not there, that will be nice.

Your group appears to know their affect very nicely. What recommendation would you give your peer groups to do the identical?

That’s a really powerful query. I’ll divide this into two items, Information Engineering and Analytics.

The success of Information Engineering is extra simply measurable. I’ve high quality, availability, course of efficiency, and efficiency metrics. 

High quality metrics measure the “correctness” of your information, and the way you measure it will depend on in the event you comply with processes. When you’ve got Jira, you will have bugs and incidents, and also you observe how briskly you’re closing bugs or fixing incidents. Over time, it’s essential to outline a high quality metric and see in case your rating improves or not.

Availability is analogous. At any time when persons are asking for a dashboard or for a question, are your sources accessible to them? In the event that they’re not, then measure and observe this, seeing in the event you’re bettering over time.

Course of Efficiency addresses the time to decision when any person asks you a query. That’s a very powerful one, as a result of it’s direct suggestions. For those who’re late, individuals will say the information group isn’t doing job, and that is all the time contemporary of their minds in the event you’re not answering.

Final is Efficiency. Your dashboard could possibly be wonderful, however it doesn’t matter if it will possibly’t assist somebody once they want it. If somebody opens a dashboard and it doesn’t load, they stroll away and it doesn’t matter how good your work was. So for me, efficiency means how rapidly a dashboard hundreds. I might measure the time a dashboard takes to load, and let’s say I’ve a goal of 10 seconds. I’ll see if all the things hundreds in that point, and what components of it are loading.

On the Analytics aspect, a simple approach to measure is to ship out an NPS type and see if persons are completely happy together with your work or not. However the different method requires you to be very process-oriented to measure it, and to make use of tickets.

As soon as each quarter, we return to all of the analytics tickets we’ve solved, and decide the affect they’ve created. I prefer to see what number of product modifications occurred due to our evaluation, and what number of enterprise selections had been made primarily based on our information.

For perception technology, we might then say we had been a part of the decision-making course of for 2 gross sales selections, two enterprise operations selections, and three product selections. The way you’ll measure that is as much as you, however it’s essential that you just measure it.

For those who’re working in a company that’s new, or hasn’t had information groups in a very long time, what occurs is that as a rule, you do 10 analyses, however solely considered one of them goes to affect the enterprise. Most of your hypotheses might be confirmed mistaken extra usually than they’re proper. You possibly can’t simply say “I did this one factor final quarter,” so documenting and having a course of helps. You want to have the ability to say “I attempted 10 hypotheses, and one labored,” versus saying “I feel we simply had one speculation that labored.”

Attempt to measure your work, and doc it nicely. You and your group could be happy with yourselves, at the very least, however you can too talk all the things you tried and contributed to.
