At a Look

- By adopting Atlan, Mistertemp’s knowledge staff may use automated column-level lineage and recognition metrics to find out which of their knowledge belongings had been used or may very well 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’s that we’re assured as a staff after we’re speaking a few 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 firms in search of expertise and other people in search of alternative, knowledge performs a key position in Mistertemp’s aim to align these events as successfully as potential.
Driving that dedication to knowledge is David Milosevic, who joined Mistertemp as Head of Information & Analytics in 2019. “My preliminary aim was to assist discover the fitting instruments, group, and options to assist everybody within the firm have a greater understanding of information,” David shared.
Even after rising into a pacesetter in its area, Mistertemp’s management refuses to be complacent. Amid the expansion of distant work, adjustments in worker expectations, and the evolving wants of firms in search of nice expertise; the steadiness between Mistertemp, the businesses they service, and the candidates they place is altering.
David defined knowledge’s position on this transformation: “Our aim 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 advertisements that we placed on job boards. How will we optimize the knowledge 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 staff has been answerable for constructing options, adopting instruments, and creating processes to help that journey. David encourages his staff to take a proactive position in how Mistertemp makes use of its knowledge, explaining, “In addition to KPIs you can placed on our groups’ efforts, we are attempting to go to the subsequent step, which is to include knowledge into our processes to enhance every of them.”
Mistertemp’s Trendy Information Stack: Atlan + Snowflake, Fivetran, Looker, Airflow, and dbt
“In my space, we’re largely specializing in what we name the Trendy Information 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 had been Airflow and dbt.
Regardless of adopting best-in-breed instruments to help 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 solution to not simply doc, however tag, determine, and shortly seek for belongings, we aren’t the homeowners of our knowledge,” David shared. “This actually resonated with our staff. 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 advanced knowledge stack. “We wanted so as to add one thing to the equation to guarantee that as soon as a necessity appeared (being a product want, a advertising want, a monetary want, a necessity from a shopper) that we may confidently say, okay, it was performed prior to now or not,” David defined.
With out this layer in place, David’s staff was answerable for scouring their knowledge property, layer by layer, every time a query about their knowledge belongings was posed. The hassle to find out what belongings existed, not to mention the character of these belongings or the efficacy of the info, was important. “Answering these questions took us loads of time,” David mentioned. “Eradicating this from the equation, and having the whole lot laid out and queryable was actually crucial if we wished to step up and implement all these future use circumstances.”
Mistertemp’s CTO successfully communicated his imaginative and prescient for the way their knowledge operate would wish to alter. It was on David and his staff to get it performed.
Atlan Arrives
After a radical seek for an energetic metadata administration platform, Mistertemp selected Atlan. “As quickly as we obtained our arms on Atlan, step one was to attach all our instruments in our stack in order that we had a giant image of the whole lot in our space of labor”, David shared. He shortly built-in Fivetran, Snowflake, dbt, and Looker with Atlan, in addition to upstream methods like Salesforce and Postgres databases, providing a transparent image of Mistertemp’s knowledge ecosystem.
“We wished to have as a lot visibility as we may, and that was very simple. We solely wanted a pair days to set it up and ensure we had been glad,” David added. “This was very easy and we had been very glad to all of a sudden see all our belongings obtainable and queryable. We may simply kind ‘contract’ and discover all tables or columns or experiences that check with that there.”
With a fast win in-hand, and visibility into how knowledge moved by their stack, David’s staff was able to put this newfound functionality into observe. “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 Properly-intended Technical Debt
Atlan’s introduction into the Mistertemp ecosystem gave David the attitude and functionality essential to simplify their advanced technical panorama.
Whereas pleased with their fashionable knowledge stack, Mistertemp’s knowledge staff struggled with navigability and manageability previous to Atlan’s arrival. “A giant aim 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 experiences which might be helpful,” David defined. “It’s really easy with fashionable knowledge stack instruments to principally join the whole lot you have got and seize the info.”
Excited by the prospect of higher servicing their enterprise companions, and with enterprise companions enthusiastic about freely obtainable knowledge, David’s staff had spent earlier years connecting quite a few downstream methods and constructing quite a few experiences for one-off questions. “Again three years in the past, the aim was to have all the info linked,” David shared.
Each time a brand new knowledge supply was requested, David’s staff as soon as discovered it best to go to Fivetran and connect with the supply system to disclose the obtainable tables. Fairly than diving into these methods to decide on solely related knowledge, it was less complicated and quicker to recreate the info in Snowflake instantly, consuming what was related downstream.
“With instruments like Fivetran, it’s very simple so as to add new connectors,” David mentioned. And over time, choices to attach and ingest knowledge for every request multiplied right into a increasingly more advanced knowledge property. A request from Mistertemp’s growth staff meant that every one Jira belongings had been synchronized, and a request from the help staff led to synchronizing each Zendesk ticket. “Why not synchronize all the info immediately? Possibly we’ll have some dashboards in place down the street,” David elaborated about their mindset on the time.
Mistertemp’s knowledge staff had been exceeding enterprise wants and had been well-intended. However with out an energetic metadata administration platform lending visibility into the implications of synchronizing a excessive quantity of information, they had been constructing technical debt, with a ballooning Snowflake footprint and quite a few unused however supported Looker experiences.
All these fast choices created loads of belongings in Snowflake that principally with out a enterprise use had been by no means actually touched or by no means actually documented or by no means actually linked to our BI software or some other software. So they simply stayed there being synchronized, costing us cash.”
“It was very simple to create experiences to showcase knowledge as one-shots, however that creates loads of debt, and loads of overhead on our staff. Our staff is barely 4 individuals,” David shared. “We wished to say in some unspecified time in the future no matter is linked and synchronized from Fivetran to Snowflake ought to be the minimal viable knowledge. We wished to ensure something that we seize was linked downstream to a use case or report that’s utilized by an finish consumer.”
The place end-to-end visibility was as soon as elusive, Atlan supplied close to instantaneous understanding of the work forward, and David’s staff had been prepared to repair Mistertemp’s long-simmering knowledge property complexity, as soon as and for all.
Deprecating Two-thirds of Their Property with Automated Column-level Lineage
Utilizing Atlan’s automated lineage, David’s staff set to work analyzing Fivetran and Snowflake, filtering belongings by whether or not or not they’d lineage, and shortly and simply figuring out which belongings had been, or weren’t, linked downstream. And with Atlan Reputation, a characteristic that reveals customers the frequency of utilization and queries towards a knowledge asset, they might decide how typically individuals used these belongings, if in any respect.
For the primary time, David’s staff had been capable of perceive the size of what they’d 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 had been used within the previous 12 months. “After the cleanup, it went right down to just a little bit lower than 600 [tables]. Greater than half our belongings had been cleaned up,” David shared.
The whole lot downstream modified. We had been capable of see each current connection in Fivetran. We may see what was really used. We saved these, and for the whole lot else, we’d disconnect.”
Atlan’s column-level lineage and utilization metrics additionally revealed that constructing one-off experiences 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%, perhaps 70% of Looker dashboards weren’t actively used and had been creating loads of overhead on the info analysts,” David mentioned. Mistertemp’s analysts had been sustaining these unused experiences as underlying belongings advanced or methods modified upstream, driving distraction and pointless effort.
Growing Context and Optimizing Information Processes, Now Obtainable in File Time
Even after deprecating as many as two-thirds of their belongings, David continued to push his staff to search out extra alternatives to optimize their knowledge property.
With the data that what remained in Snowflake was helpful to their enterprise companions, Mistertemp’s knowledge staff started the method of correctly tagging and documenting the remaining belongings. “Earlier than final yr, 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 concept of how typically belongings are used, Mistertemp’s knowledge staff now optimizes how typically knowledge is synchronized, saving computing prices by selecting an acceptable cadence (month-to-month reasonably than hourly, for example) that matches enterprise wants. And with their newfound visibility into their Looker panorama, they might merge comparable experiences to scale 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 prevented unnecessarily including context to a whole lot of tables and belongings. “Which may not be the configuration for each firm, however now we have loads of prospects and solely 4 individuals making an attempt to catch up,” mentioned David. “We wanted to search out an environment friendly manner to assist us scale, and never linearly.”
Making a Clear Information Property with Atlan
Months after cleansing up their knowledge property with Atlan’s automated lineage and utilization metrics, Mistertemp’s knowledge staff continues to reap the advantages.
The massive distinction now’s that we’re assured as a staff after we’re speaking a few knowledge asset.”
When requested a few knowledge asset, David’s staff can now, at a look, decide whether or not or not it’s getting used, the place it’s getting used, and the way often it’s getting used and synchronized. If belongings or experiences exist already, their enterprise companions shortly get what they should make extra data-driven choices. And if one thing new must be created, the info staff can extra shortly reply with an answer method that features the fitting knowledge sources, the fitting documentation, and the fitting visualization.
“All of that’s principally solely in a single place,” mentioned David. “Earlier than, it was a dialogue we needed to have with a number of individuals within the staff. We wanted to determine principally from one software to a different software. We went from being just a little bit chaotic to just a little bit extra streamlined, and anybody within the staff is ready to reply questions.”
No matter the place knowledge lived or what type 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 decreasing these discussions and ensuring we spend extra time on motion.”
And with this better focus, and time saved, David’s staff is taking a extra proactive position in enhancing the Mistertemp enterprise. Most not too long ago, they contributed to a mission to enhance Value per Hiring, a key enterprise metric.
“I feel it’s a type of matters now we have wished to resolve for so long as I’ve been right here, for greater than three years. We obtained bored with not with the ability to determine the issues we would have liked to shift or clear up or put collectively,” David defined. “I feel with the assistance of Atlan, we had 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 fitting 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 had been keen to do, however by no means discovered time, vitality, or instruments to resolve.”
A Extra Assured Information Staff
Reflecting on his and his staff’s journey, David continues to return to the identical feeling: confidence.
Mistertemp’s knowledge staff is reworking into a real enterprise enabler, proactive of their method 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. “Folks depend on us just a little bit extra now that we will precisely give them solutions to their questions, perhaps 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 particular person, a advertising particular person, we simply wish to guarantee that everybody finds a manner to enhance their every day routine. It’s not solely cleansing up for the info staff to be assured, but it surely’s the primary stone to ensure that everybody to have the ability to construct on high of that.”
