What’s subsequent for the way forward for information engineering? Every year, we chat with considered one of our business’s pioneering leaders about their predictions for the fashionable information stack – and share just a few of our personal.
Just a few weeks in the past, I had the chance to speak with famed enterprise capitalist, prolific blogger, and good friend Tomasz Tunguz about his prime 9 information engineering predictions for 2023. It seemed like a lot enjoyable that I made a decision to seize my crystal ball and add just a few ideas to the combo.
Earlier than we start, nonetheless, it is necessary to know what precisely we imply by trendy information stack:
- It is cloud-based
- It is modular and customizable
- It is best-of-breed first (selecting the perfect software for a selected job, versus an all-in-one answer)
- It is metadata-driven
- It runs on SQL (not less than for now)
With these fundamental ideas in thoughts, let’s dive into Tomasz’s predictions for the way forward for the fashionable information stack.
Professional-tip: make sure you try his speak from IMPACT: The Knowledge Observability Summit.
Prediction #1: Cloud Manages 75% Of All Knowledge Workloads by 2024 (Tomasz)

This was Tomasz’s first prediction, and based mostly on an analyst report earlier this 12 months displaying the expansion of cloud versus on-premises RDBMS income.
In 2017, cloud was about 20% of on-prem, and thru the course of the final 5 years, the cloud has mainly achieved equality when it comes to income. For those who venture three or 4 years, given the expansion charge we’re seeing right here, about 75% of all these workloads might be migrating to the cloud.
The opposite statement he had was that on-prem spend has mainly been flat all through that interval. That provides a whole lot of credence to the thought you may have a look at Snowflake’s revenues as a proxy for what’s taking place within the bigger information ecosystem.
Snowflake went from 100 million in income to about 1.2 billion in 4 years, which underscores the terrific demand there may be for cloud information warehouses.
Prediction #2: Knowledge Engineering Groups Will Spend 30% Extra Time On FinOps / Knowledge Cloud Price Optimization (Barr)
By way of FinOps Basis
My first prediction is a corollary to Tomasz’s prophecy on the speedy progress of knowledge cloud spend. As extra information workloads transfer to the cloud, I foresee that information will grow to be a bigger portion of an organization’s spend and draw extra scrutiny from finance.
It is no secret that the macro financial setting is beginning to transition from a interval of speedy progress and income acquisition to a extra restrained deal with optimizing operations and profitability. We’re seeing extra monetary officers play rising roles in offers with information groups and it stands to purpose this partnership may even embody recurring prices as effectively.
Knowledge groups will nonetheless have to primarily add worth to the enterprise by performing as a power multiplier on the effectivity of different groups and by rising income via information monetization, however value optimization will grow to be an more and more necessary third avenue.
That is an space the place finest practices are nonetheless very nascent as information engineering groups have centered on pace and agility to satisfy the extraordinary calls for positioned on them. Most of their time is spent writing new queries or piping in additional information vs. optimizing heavy/deteriorating queries or deprecating unused tables.
Knowledge cloud value optimization can be in the perfect curiosity of the info warehouse and lakehouse distributors. Sure, in fact they need consumption to extend, however waste creates churn. They might somewhat encourage elevated consumption from superior use circumstances like information functions that create buyer worth and due to this fact elevated retention. They are not on this for the short-term.
That is why you’re seeing value of possession grow to be a much bigger a part of the dialogue, because it was in my dialog at a latest convention session with Databricks CEO Ali Ghodsi. You might be additionally seeing all the different main players-BigQuery, RedShift, Snowflake-highlight finest practices and options round optimization.
This enhance in time spent will doubtless come each from extra headcount, which might be extra immediately tied to ROI and extra simply justified as hires come underneath elevated scrutiny (a survey from the FinOps basis forecasts a median progress of 5 to 7 FinOps devoted workers). Time allocation may even doubtless shift inside present members of the info group as they undertake extra processes and applied sciences to grow to be environment friendly in different areas like information reliability.
Prediction #3: Knowledge Workloads Section By Use (Tomasz)

Tomasz’ second prediction centered on information groups emphasizing utilizing the fitting software for the fitting job, or maybe the specialised software for the specialised job.
The RBMS market has grown from about 36 billion to about 80 billion from 2017 to 2021, and most of these workloads have been centralized in cloud information warehouses. However now we’re beginning to see segmentation.
Totally different workloads are going to want completely different sorts of databases. The best way Tomasz sees it, right this moment the whole lot is working in a cloud information warehouse, however within the subsequent few years there might be a gaggle of workloads which might be pushed into in-memory databases, significantly for smaller information units. Consider, the overwhelming majority of cloud information workloads are in all probability lower than 100 gigabytes in measurement and one thing you possibly can do on a selected machine in reminiscence for increased efficiency.
Tomasz additionally predicts significantly giant enterprises who’ve completely different wants for his or her information workloads might begin to take jobs that do not require low latency or the manipulation of great volumes of knowledge and really transfer them to cloud information lakehouses.
Prediction #4: Extra Specialization Throughout the Knowledge Group (Barr)

I agree with Tomasz’s prediction on the specialization of knowledge workloads, however I do not assume it is solely the info warehouse that is going to section by use. I believe we’re going to begin seeing extra specialised roles throughout information groups as effectively.
Presently, information group roles are segmented primarily by information processing stage:
- Knowledge engineers pipe the info in,
- Analytical engineers clear it up, and
- Knowledge analysts/scientists visualize and glean insights from it.
These roles aren’t going wherever, however I believe there might be extra segmentation by enterprise worth or goal:
- Knowledge reliability engineers will guarantee information high quality
- Knowledge product managers will increase adoption and monetization
- DataOps engineers will deal with governance and effectivity
- Knowledge architects will deal with eradicating silos and longer-term investments
This could mirror our sister discipline of software program engineering the place the title of software program engineer began to separate into subfields like DevOps engineer or website reliability engineer. It is a pure evolution as professions begin to mature and grow to be extra advanced.
Prediction #5: Metrics Layers Unify Knowledge Architectures (Tomasz)
Tomasz’s subsequent prediction handled the ascendance of the metrics layer, often known as the semantics layer. This made an enormous splash at dbt’s Coalesce the final two years and it is going to begin remodeling the best way information pipelines and information operations look.
Picture courtesy of Tomasz Tunguz.
Right now, the traditional information pipeline has an ETL layer that is taking information from completely different methods, and placing it right into a cloud information warehouse. You’ve got obtained a metrics layer within the center that defines metrics like income as soon as after which it is used downstream in BI for constant reporting and the whole firm can use it. That is the primary worth proposition of that metrics mannequin. This expertise and thought has existed for many years, however it’s actually come to the fore fairly not too long ago.

As Tomasz suggests, now corporations require a machine studying stack, which seems similar to the traditional BI stack, however it’s truly constructed a whole lot of its personal infrastructure individually. You continue to have the ETL that will get put right into a cloud information warehouse, however now you have obtained a characteristic retailer, which is a database of the metrics that information scientists use in an effort to prepare machine studying fashions and finally serve them.
Nonetheless, in the event you have a look at these two architectures, they’re truly fairly comparable. And it isn’t arduous to see how the metrics layer and the characteristic retailer may come collectively and align these two information pipelines as a result of each of them are defining metrics which might be used downstream.
In the end, Tomasz argues, the logical conclusion is that a whole lot of the machine studying work right this moment ought to transfer into the cloud information warehouse, or the database of alternative, as a result of these platforms are accustomed to serving very giant question volumes with very excessive availability.
Prediction #6: Knowledge Will get Meshier, However Central Knowledge Platforms Stay (Barr)

I agree with Tomasz. The metrics layer is promising indeed- information groups want a shared understanding and single supply of fact particularly as they transfer towards extra decentralized, distributed constructions, which is the guts of my subsequent prediction.
Predicting information groups will proceed to transition towards a information mesh as initially outlined by Zhamak Dehgani is just not essentially daring. Knowledge mesh has been one of many hottest ideas amongst information groups for a number of years now.
Nonetheless, I’ve seen extra information groups making a pitstop on their journey that mixes area embedded groups and a middle of excellence or platform group. For a lot of groups this organizing precept provides them the perfect of each worlds: the agility and alignment of decentralized groups and the constant requirements of centralized groups.
I believe some groups will proceed on their information mesh journey and a few will make this pitstop a everlasting vacation spot. They’ll undertake information mesh ideas equivalent to area-first architectures, self-service, and treating information like a product-but they are going to retain a robust central platform and information engineering SWAT group.
Prediction #7: Notebooks Win 20% of Excel Customers With Knowledge Apps (Tomasz)
Picture courtesy of Tomasz Tunguz.
Tomasz’s subsequent prediction derived from his dialog with a handful of knowledge leaders from FORTUNE 500 corporations just a few years in the past.
He requested them, “There are a billion customers of Excel on the planet, a few of that are inside your organization. What fraction of these Excel customers write Python right this moment and what is going to that proportion be in 5 years?”
The reply was 5% of people that use Excel right this moment write Python, however in 5 years, it will be 50%. That is a reasonably basic change and it implies they will be 250 million individuals searching for a subsequent era information evaluation software that does one thing like Excel, however in a superior means.
That software may very well be the Jupyter pocket book. It is obtained all some great benefits of code: it is reproducible, you may verify it in GitHub, and it is very easy to share. It may grow to be the dominant mechanism for changing Excel for these extra subtle customers and use circumstances equivalent to information apps.
An information engineer can take a pocket book, write a bunch of code even throughout completely different languages, pull in several information sources, merge them collectively, construct an software, after which publish this software to their finish customers.
That is a extremely spectacular and necessary pattern. As a substitute of passing round an Excel spreadsheet, Tomasz suggests, individuals can construct an software that appears and looks like an actual SaaS software, however custom-made to their customers.
Prediction #8: Most machine studying fashions (>51%) will efficiently make it to manufacturing (Barr)
Within the spirit of Tomasz’s pocket book prediction, I consider we’ll see the common group efficiently deploy extra machine studying fashions into manufacturing.
For those who attended any tech conferences in 2022, you may assume we’re all dwelling in ML nirvana; in spite of everything, the profitable tasks are sometimes impactful and enjoyable to spotlight. However that obscures the truth that most ML tasks fail earlier than they ever see the sunshine of day.
In October 2020, Gartner reported that solely 53% of ML tasks make it from prototype to production-and that is at organizations with some degree of AI expertise. For corporations nonetheless working to develop a data-driven tradition, that quantity is probably going far increased, with some failure-rate estimates hovering to 80% or extra.
There are a whole lot of challenges, together with
- Misalignment between enterprise wants and machine studying aims,
- Machine studying coaching that does not generalize,
- Testing and validation points, and
- Deployment and serving hurdles.
The explanation why I believe the tide begins to show for ML engineering groups is the mix of elevated deal with information high quality and the financial strain to make ML extra usable (of which extra approachable interfaces like notebooks or information apps like Steamlit play an enormous half).
Prediction #8: “Cloud-Prem” Turns into The Norm (Tomasz)
Tomasz’s subsequent prediction addressed the closing chasm between completely different information infrastructures and customers much like his metrics layer prediction.
The outdated structure for information motion was a corporation that may have, within the case of the picture above, three completely different items of software program. The CRM for gross sales, a CDP for advertising, after which the finance database. The information inside these databases doubtless overlap.
What you’ll see within the outdated structure (nonetheless very prevalent right this moment) is you’re taking all that information, you pump it into the info warehouse, and you then pump it again out to counterpoint different merchandise like a buyer success product.
The following era of structure goes to be a learn and write cloud information warehouse the place the gross sales database, the advertising database, the finance database, and the client success info, they’re all saved on a cloud information warehouse with a bi-directional sync throughout them
There are a few completely different benefits to this structure. The primary is it is truly a go to market benefit. If an enormous cloud information warehouse comprises information from an enormous financial institution, they’ve gone via the data safety course of in an effort to get the approval to govern that info, the SaaS functions constructed on prime of that cloud information warehouse solely have to get permissions to that data-you now not have to undergo the data safety course of, which makes your gross sales cycles considerably sooner.
The opposite principal profit as a software program supplier, Tomasz suggests, is that you are going to have the ability to use and be part of info throughout these information units. That is doubtless an inexorable pattern that is in all probability going to proceed for not less than the following 10 to fifteen years.
Prediction #9: Knowledge contracts transfer to early stage adoption (Barr)

Anybody who follows information discussions on LinkedIn is aware of that information contracts have been among the many most mentioned matters of the 12 months. There is a purpose why: they handle one of many largest information high quality points information groups face.
Surprising schema modifications account for a big portion of knowledge high quality points. Most of the time, they’re the results of an unwitting software program engineer who has pushed an replace to a service not realizing they’re creating havoc within the information methods downstream (maybe as a result of they do not have visibility into information lineage).
Nonetheless it is necessary to notice that given all the web chatter, information contracts are nonetheless very a lot of their infancy. The pioneers of this process-people like Chad Sanderson and Andrew Jones-have proven the way it can transfer from idea to apply, however they’re additionally very straight ahead that it is nonetheless a piece in progress at their respective organizations.
I predict the power and significance of this matter will speed up its implementation from pioneers to early stage adopters in 2023. This can set the stage for what might be an inflection level in 2024 the place it begins to cross the chasm right into a mainstream finest apply or begins to fade away.
