At a Look

- By adopting Atlan, Mistertemp’s information staff might use automated column-level lineage and recognition metrics to find out which of their information belongings had been used or may very well be deprecated.
- In consequence, Mistertemp was capable of deprecate half of their Snowflake tables, representing two-thirds of their information belongings, and over 60% of their Looker belongings.
The large distinction now’s that we’re assured as a staff after we’re speaking a couple of information asset.”
Primarily based in France, Mistertemp is a market chief in short-term work placements, servicing over 12,000 purchasers and 55,000 staff in 2022. As a dealer between corporations in search of expertise and other people in search of alternative, information performs a key function in Mistertemp’s purpose to align these events as successfully as attainable.
Driving that dedication to information is David Milosevic, who joined Mistertemp as Head of Information & Analytics in 2019. “My preliminary purpose was to assist discover the best 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 corporations in search of nice expertise; the stability between Mistertemp, the businesses they service, and the candidates they place is altering.
David defined information’s function on this transformation: “Our purpose is to see how we are able to optimize all of the exchanges we have now with these completely different events — sharing info from our must job boards, for instance, or getting purposes 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 information, and David’s staff has been liable for constructing options, adopting instruments, and creating processes to help that journey. David encourages his staff to take a proactive function in how Mistertemp makes use of its information, explaining, “In addition to KPIs that you could placed on our groups’ efforts, we are attempting to go to the following step, which is to include information 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 deciding on Fivetran to ingest information, Mistertemp’s foundational decisions for his or her stack included Snowflake as their information 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 offer credit score to our CTO [Francois-Emmanuel Piacentini]. His mindset was that till we have now a technique to not simply doc, however tag, determine, and rapidly seek for belongings, we’re not the house owners of our information,” 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 information stack. “We wanted so as to add one thing to the equation to be sure that as soon as a necessity appeared (being a product want, a advertising and marketing want, a monetary want, a necessity from a consumer) that we might confidently say, okay, it was performed up to now or not,” David defined.
With out this layer in place, David’s staff was liable for scouring their information property, layer by layer, every time a query about their information belongings was posed. The trouble to find out what belongings existed, not to mention the character of these belongings or the efficacy of the info, was vital. “Answering these questions took us lots of time,” David mentioned. “Eradicating this from the equation, and having the whole lot laid out and queryable was actually vital if we wished to step up and implement all these future use instances.”
Mistertemp’s CTO successfully communicated his imaginative and prescient for a way their information perform would wish to vary. It was on David and his staff to get it performed.
Atlan Arrives
After an intensive seek for an energetic metadata administration platform, Mistertemp selected Atlan. “As quickly as we bought our palms 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 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 information ecosystem.
“We wished to have as a lot visibility as we might, and that was very simple. We solely wanted a pair days to set it up and ensure we had been happy,” David added. “This was very easy and we had been very happy to out of the blue see all our belongings accessible and queryable. We might simply kind ‘contract’ and discover all tables or columns or studies that discuss with that there.”
With a fast win in-hand, and visibility into how information moved by their stack, David’s staff 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 Properly-intended Technical Debt
Atlan’s introduction into the Mistertemp ecosystem gave David the angle and functionality essential to simplify their advanced technical panorama.
Whereas pleased with their trendy information stack, Mistertemp’s information staff struggled with navigability and manageability previous to Atlan’s arrival. “An enormous purpose we had, and need to proceed to pursue, is that we need to guarantee what we have now in Snowflake or Looker are solely information or studies which might be helpful,” David defined. “It’s really easy with trendy information stack instruments to principally join the whole lot you’ve got and seize the info.”
Excited by the prospect of higher servicing their enterprise companions, and with enterprise companions enthusiastic about freely accessible information, David’s staff had spent earlier years connecting quite a few downstream techniques and constructing quite a few studies for one-off questions. “Again three years in the past, the purpose was to have all the info linked,” David shared.
At any time when a brand new information supply was requested, David’s staff as soon as discovered it best to go to Fivetran and hook up with the supply system to disclose the accessible tables. Reasonably than diving into these techniques to decide on solely related information, 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 information for every request multiplied right into a increasingly advanced information property. A request from Mistertemp’s improvement staff meant that each 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 instantly? Possibly we’ll have some dashboards in place down the highway,” David elaborated about their mindset on the time.
Mistertemp’s information staff had been exceeding enterprise wants and had been well-intended. However with out an energetic metadata administration platform lending visibility into the results 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 studies.
All these fast choices created lots of belongings in Snowflake that principally with no enterprise use had been by no means actually touched or by no means actually documented or by no means actually linked to our BI device or every other device. So they simply stayed there being synchronized, costing us cash.”
“It was very simple to create studies to showcase information as one-shots, however that creates lots of debt, and lots of overhead on our staff. Our staff is simply 4 individuals,” David shared. “We wished to say sooner or later no matter is linked and synchronized from Fivetran to Snowflake ought to be the minimal viable information. We wished to verify 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 information 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 staff set to work analyzing Fivetran and Snowflake, filtering belongings by whether or not or not they’d lineage, and rapidly and simply figuring out which belongings had been, or weren’t, linked downstream. And with Atlan Reputation, a characteristic that exhibits customers the frequency of utilization and queries towards a knowledge asset, they may decide how usually individuals used these belongings, if in any respect.
For the primary time, David’s staff had been capable of perceive the dimensions 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 all the way down to slightly 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 might see what was really used. We stored these, and for the whole lot else, we might disconnect.”
Atlan’s column-level lineage and utilization metrics additionally revealed that constructing one-off studies 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 had been creating lots of overhead on the info analysts,” David mentioned. Mistertemp’s analysts had been sustaining these unused studies as underlying belongings advanced or techniques modified upstream, driving distraction and pointless effort.
Rising Context and Optimizing Information Processes, Now Out there in File Time
Even after deprecating as many as two-thirds of their belongings, David continued to push his staff to seek out extra alternatives to optimize their information property.
With the data that what remained in Snowflake was helpful to their enterprise companions, Mistertemp’s information staff started the method of correctly tagging and documenting the remaining belongings. “Earlier than final 12 months, earlier than we began considering 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 information, accessible to all.
With a transparent concept of how usually belongings are used, Mistertemp’s information staff now optimizes how usually information is synchronized, saving computing prices by selecting an acceptable cadence (month-to-month relatively than hourly, for example) that matches enterprise wants. And with their newfound visibility into their Looker panorama, they may merge comparable studies to cut back Mistertemp’s BI footprint and enhance maintainability.
And at last, by figuring out the recognition of their information belongings, then deprecating them previous to tagging and defining phrases, Mistertemp averted unnecessarily including context to tons of of tables and belongings. “That may not be the configuration for each firm, however we have now lots of clients and solely 4 individuals attempting to catch up,” mentioned David. “We wanted to seek out an environment friendly means to assist us scale, and never linearly.”
Making a Clear Information Property with Atlan
Months after cleansing up their information property with Atlan’s automated lineage and utilization metrics, Mistertemp’s information staff continues to reap the advantages.
The large distinction now’s that we’re assured as a staff after we’re speaking a couple of information asset.”
When requested a couple of information 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 incessantly it’s getting used and synchronized. If belongings or studies exist already, their enterprise companions rapidly get what they should make extra data-driven choices. And if one thing new must be created, the info staff can extra rapidly reply with an answer method that features the best information sources, the best documentation, and the best 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 device to a different device. We went from being slightly bit chaotic to slightly bit extra streamlined, and anybody within the staff is ready to reply questions.”
No matter the place information lived or what type it took, Atlan turned Mistertemp’s first step to resolving enterprise wants. “We all know as soon as we have now 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 higher focus, and time saved, David’s staff is taking a extra proactive function in enhancing the Mistertemp enterprise. Most lately, they contributed to a undertaking to enhance Value per Hiring, a key enterprise metric.
“I feel it’s a type of matters we have now wished to resolve for so long as I’ve been right here, for greater than three years. We bought uninterested in not having 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 best 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 Crew
Reflecting on his and his staff’s journey, David continues to return to the identical feeling: confidence.
Mistertemp’s information staff is reworking into a real enterprise enabler, proactive of their method to sustaining their information 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 slightly bit extra now that we are able to precisely give them solutions to their questions, possibly not instantaneously, however in a short time.”
“We’re simply in the beginning of our journey with Atlan,” David concluded. “Whether or not you’re a product proprietor, a developer, a monetary particular person, a advertising and marketing particular person, we simply need to be sure that everybody finds a means to enhance their every day routine. It’s not solely cleansing up for the info staff to be assured, nevertheless it’s the primary stone to ensure that everybody to have the ability to construct on prime of that.”
