From Chaos to Confidence: How Mistertemp Optimized their Trendy Knowledge Stack with Atlan – Atlan


Recruitment and Momentary Work Placements Chief Makes use of Automated Lineage to Deprecate Two-thirds of Knowledge Warehouse Belongings

At a Look

  • Mistertemp, a frontrunner in recruitment and short-term work based mostly in France, sought to enhance the navigability and value of their newly carried out fashionable knowledge stack (Snowflake, Fivetran, Looker, Airflow, and dbt).
  • By adopting Atlan, Mistertemp’s knowledge workforce might use automated column-level lineage and recognition metrics to find out which of their knowledge belongings have been used or could possibly be deprecated.
  • Because of this, Mistertemp was capable of deprecate half of their Snowflake tables, representing two-thirds of their knowledge belongings, and over 60% of their Looker belongings.

The massive distinction now could be that we’re assured as a workforce after we’re speaking a couple of knowledge asset.”

Based mostly in France, Mistertemp is a market chief in short-term work placements, servicing over 12,000 purchasers and 55,000 employees in 2022. As a dealer between corporations searching for expertise and other people searching for alternative, knowledge performs a key function in Mistertemp’s objective to align these events as successfully as potential.

Driving that dedication to knowledge is David Milosevic, who joined Mistertemp as Head of Knowledge & Analytics in 2019. “My preliminary objective was to assist discover the appropriate instruments, group, and options to assist everybody within the firm have a greater understanding of knowledge,” David shared.

Even after rising into a frontrunner in its house, Mistertemp’s management refuses to be complacent. Amid the expansion of distant work, adjustments in worker expectations, and the evolving wants of corporations searching for nice expertise; the steadiness between Mistertemp, the businesses they service, and the candidates they place is altering.

David defined knowledge’s function on this transformation: “Our objective is to see how we will optimize all of the exchanges now we have with these totally different events — sharing info from our must job boards, for instance, or getting functions for these adverts that we placed on job boards. How can we optimize the data we get in order that they are often matched with the wants of purchasers and vice versa?”

To navigate their altering market, it’s essential that Mistertemp successfully use its knowledge, and David’s workforce has been accountable for constructing options, adopting instruments, and creating processes to assist that journey. David encourages his workforce to take a proactive function in how Mistertemp makes use of its knowledge, explaining, “In addition to KPIs which you could placed on our groups’ efforts, we try to go to the subsequent step, which is to include knowledge into our processes to enhance every of them.”

Mistertemp’s Trendy Knowledge Stack: Atlan + Snowflake, Fivetran, Looker, Airflow, and dbt

“In my space, we’re largely specializing in what we name the Trendy Knowledge Stack,” David shared. Initially choosing Fivetran to ingest knowledge, Mistertemp’s foundational decisions for his or her stack included Snowflake as their knowledge warehouse and Looker as their BI layer. Added later have been Airflow and dbt.

Regardless of adopting best-in-breed instruments to assist their transformation, Mistertemp’s management felt {that a} piece was lacking. “I’ve to provide credit score to our CTO [Francois-Emmanuel Piacentini]. His mindset was that till now we have a technique to not simply doc, however tag, establish, and rapidly seek for belongings, we aren’t the homeowners of our knowledge,” David shared. “This actually resonated with our workforce. For a very long time, we couldn’t put our finger on what was lacking.”

Mistertemp wanted a governance and collaboration layer, built-in to and able to navigating their more and more complicated knowledge stack. “We would have liked so as to add one thing to the equation to make it possible for as soon as a necessity appeared (being a product want, a advertising want, a monetary want, a necessity from a shopper) that we might confidently say, okay, it was executed up to now or not,” David defined.

With out this layer in place, David’s workforce was accountable for scouring their knowledge property, layer by layer, every time a query about their knowledge belongings was posed. The trouble to find out what belongings existed, not to mention the character of these belongings or the efficacy of the information, was vital. “Answering these questions took us a number of time,” David stated. “Eradicating this from the equation, and having the whole lot laid out and queryable was actually obligatory if we wished to step up and implement all these future use instances.”

Mistertemp’s CTO successfully communicated his imaginative and prescient for the way their knowledge perform would wish to alter. It was on David and his workforce to get it executed.

Atlan Arrives

After a radical seek for an lively metadata administration platform, Mistertemp selected Atlan. “As quickly as we bought our arms on Atlan, step one was to attach all our instruments in our stack in order that we had an enormous image of the whole lot in our space of labor”, David shared. He rapidly built-in Fivetran, Snowflake, dbt, and Looker with Atlan, in addition to upstream techniques like Salesforce and Postgres databases, providing a transparent image of Mistertemp’s knowledge ecosystem.

“We wished to have as a lot visibility as we might, and that was very straightforward. We solely wanted a pair days to set it up and ensure we have been glad,” David added. “This was very easy and we have been very glad to instantly see all our belongings out there and queryable. We might simply kind ‘contract’ and discover all tables or columns or reviews that check with that there.”

With a fast win in-hand, and visibility into how knowledge moved via their stack, David’s workforce was able to put this newfound functionality into apply. “Step one was very easy and really rewarding. However that was not only for the enjoyable of it,” David defined, alluding to far larger ambitions with Atlan.

Utilizing Atlan to Resolve Nicely-intended Technical Debt

Atlan’s introduction into the Mistertemp ecosystem gave David the attitude and functionality essential to simplify their complicated technical panorama.

Whereas pleased with their fashionable knowledge stack, Mistertemp’s knowledge workforce struggled with navigability and manageability previous to Atlan’s arrival. “A giant objective we had, and wish to proceed to pursue, is that we wish to guarantee what now we have in Snowflake or Looker are solely knowledge or reviews which are helpful,” David defined. “It’s really easy with fashionable knowledge stack instruments to principally join the whole lot you’ve and seize the information.”

Excited by the prospect of higher servicing their enterprise companions, and with enterprise companions enthusiastic about freely out there knowledge, David’s workforce had spent earlier years connecting quite a few downstream techniques and constructing quite a few reviews for one-off questions. “Again three years in the past, the objective was to have all the information related,” David shared.

Each time a brand new knowledge supply was requested, David’s workforce as soon as discovered it best to go to Fivetran and connect with the supply system to disclose the out there tables. Slightly than diving into these techniques to decide on solely related knowledge, it was easier and sooner to recreate the information in Snowflake instantly, consuming what was related downstream.

“With instruments like Fivetran, it’s very straightforward so as to add new connectors,” David stated. And over time, choices to attach and ingest knowledge for every request multiplied right into a increasingly more complicated knowledge property. A request from Mistertemp’s growth workforce meant that every one Jira belongings have been synchronized, and a request from the assist workforce led to synchronizing each Zendesk ticket. “Why not synchronize all the information instantly? Possibly we’ll have some dashboards in place down the street,” David elaborated about their mindset on the time. 

Mistertemp’s knowledge workforce had been exceeding enterprise wants and have been well-intended. However with out an lively metadata administration platform lending visibility into the implications of synchronizing a excessive quantity of knowledge, they have been constructing technical debt, with a ballooning Snowflake footprint and quite a few unused however supported Looker reviews. 

All these fast choices created a number of belongings in Snowflake that principally with no enterprise use have been by no means actually touched or by no means actually documented or by no means actually related to our BI device or every other device. So they simply stayed there being synchronized, costing us cash.

“It was very straightforward to create reviews to showcase knowledge as one-shots, however that creates a number of debt, and a number of overhead on our workforce. Our workforce is simply 4 folks,” David shared. “We wished to say in some unspecified time in the future no matter is related and synchronized from Fivetran to Snowflake must be the minimal viable knowledge. We wished to verify something that we seize was related downstream to a use case or report that’s utilized by an finish person.”

The place end-to-end visibility was as soon as elusive, Atlan supplied close to instantaneous understanding of the work forward, and David’s workforce have been prepared to repair Mistertemp’s long-simmering knowledge property complexity, as soon as and for all.

Deprecating Two-thirds of Their Belongings with Automated Column-level Lineage

Utilizing Atlan’s automated lineage, David’s workforce started working analyzing Fivetran and Snowflake, filtering belongings by whether or not or not that they had lineage, and rapidly and simply figuring out which belongings have been, or weren’t, related downstream. And with Atlan Reputation, a characteristic that reveals customers the frequency of utilization and queries towards a knowledge asset, they may decide how usually folks used these belongings, if in any respect.

For the primary time, David’s workforce have been capable of perceive the dimensions of what that they had been sustaining. Of their 1,500 tables and 30,000 belongings on Snowflake, fewer than half of the tables and one-third of the belongings have been used within the previous 12 months. “After the cleanup, it went right down to a bit of bit lower than 600 [tables]. Greater than half our belongings have been cleaned up,” David shared.

All the things downstream modified. We have been capable of see each current connection in Fivetran. We might see what was really used. We stored these, and for the whole lot else, we’d disconnect.”

Atlan’s column-level lineage and utilization metrics additionally revealed that constructing one-off reviews had additionally exacted a price. Mistertemp’s BI layer had ample alternative for cleanup, with 60% of their belongings like dashboards, views, dimensions, and measures going unused. 

I feel 60%, possibly 70% of Looker dashboards weren’t actively used and have been creating a number of overhead on the information analysts,” David stated. Mistertemp’s analysts had been sustaining these unused reviews as underlying belongings advanced or techniques modified upstream, driving distraction and pointless effort.

Rising Context and Optimizing Knowledge Processes, Now Accessible in File Time

Even after deprecating as many as two-thirds of their belongings, David continued to push his workforce to seek out extra alternatives to optimize their knowledge property.

With the information that what remained in Snowflake was helpful to their enterprise companions, Mistertemp’s knowledge workforce started the method of correctly tagging and documenting the remaining belongings. “Earlier than final 12 months, earlier than we began pondering of utilizing Atlan or different instruments, we considered utilizing Snowflake or Looker,” shared David. However with Atlan, asset documentation is accessible to colleagues who don’t use Snowflake or Looker, laying the groundwork for a single level of context for Mistertemp’s enterprise knowledge, accessible to all.

With a transparent thought of how usually belongings are used, Mistertemp’s knowledge workforce now optimizes how usually knowledge is synchronized, saving computing prices by selecting an acceptable cadence (month-to-month moderately than hourly, as an illustration) that matches enterprise wants. And with their newfound visibility into their Looker panorama, they may merge comparable reviews to cut back Mistertemp’s BI footprint and enhance maintainability.

And eventually, by figuring out the recognition of their knowledge belongings, then deprecating them previous to tagging and defining phrases, Mistertemp averted unnecessarily including context to a whole lot of tables and belongings. “That may not be the configuration for each firm, however now we have a number of clients and solely 4 folks attempting to catch up,” stated David. “We would have liked to seek out an environment friendly method to assist us scale, and never linearly.”

Making a Clear Knowledge Property with Atlan

Months after cleansing up their knowledge property with Atlan’s automated lineage and utilization metrics, Mistertemp’s knowledge workforce continues to reap the advantages. 

The massive distinction now could be that we’re assured as a workforce after we’re speaking a couple of knowledge asset.”

When requested a couple of knowledge asset, David’s workforce can now, at a look, decide whether or not or not it’s getting used, the place it’s getting used, and the way ceaselessly it’s getting used and synchronized. If belongings or reviews exist already, their enterprise companions rapidly get what they should make extra data-driven choices. And if one thing new must be created, the information workforce can extra rapidly reply with an answer strategy that features the appropriate knowledge sources, the appropriate documentation, and the appropriate visualization.

“All of that’s principally solely in a single place,” stated David. “Earlier than, it was a dialogue we needed to have with a number of folks within the workforce. We would have liked to determine principally from one device to a different device. We went from being a bit of bit chaotic to a bit of bit extra streamlined, and anybody within the workforce is ready to reply questions.”

No matter the place knowledge lived or what kind it took, Atlan turned Mistertemp’s first step to resolving enterprise wants. “We all know as soon as now we have written this down, anybody that has a query can discover the reply no matter their layer,” David shared. “I’ll emphasize how a lot time this will save us, simply lowering these discussions and ensuring we spend extra time on motion.”

And with this larger focus, and time saved, David’s workforce is taking a extra proactive function in enhancing the Mistertemp enterprise. Most not too long ago, they contributed to a undertaking to enhance Value per Hiring, a key enterprise metric. 

“I feel it’s a kind of matters now we have wished to unravel for so long as I’ve been right here, for greater than three years. We bought bored with not with the ability to establish the issues we wanted to shift or clear up or put collectively,” David defined. “I feel with the assistance of Atlan, we have been capable of settle every of these arguments one after the other by both having the right definition put into the glossary, or by having the appropriate lineage displayed in entrance of us so that everybody talks the identical language. It’s a mixture of instruments we didn’t have earlier than that helped us crack that equation that we have been keen to do, however by no means discovered time, vitality, or instruments to unravel.”

A Extra Assured Knowledge Staff

Reflecting on his and his workforce’s journey, David continues to return to the identical feeling: confidence.

Mistertemp’s knowledge workforce is remodeling into a real enterprise enabler, proactive of their strategy to sustaining their knowledge property, and on the prepared with the solutions and options their enterprise companions want. “It’s no extra a query of ‘ought to we’. It’s extra like ‘how can we?,” David shared. “Individuals depend on us a bit of bit extra now that we will precisely give them solutions to their questions, possibly not instantaneously, however in a short time.”

“We’re simply at first of our journey with Atlan,” David concluded. “Whether or not you’re a product proprietor, a developer, a monetary individual, a advertising individual, we simply wish to make it possible for everybody finds a method to enhance their day by day routine. It’s not solely cleansing up for the information workforce to be assured, however it’s the primary stone to ensure that everybody to have the ability to construct on prime of that.
