That includes the 6 huge concepts you need to know from 2021
As the info world slowed down for the vacations, I received some downtime to step again and take into consideration the final yr. And I can’t assist however assume, wow, what a yr it’s been!
Is it simply me, or did knowledge undergo 5 years’ value of change in 2021?
It’s partially COVID time, the place a month appears like a day and a yr on the similar time. You’d blink, and immediately there can be a brand new buzzword dominating Knowledge Twitter. It’s additionally partially the deluge of VC cash and loopy startup rounds, which added gas to the yr’s knowledge hearth.
With a lot hype, it’s onerous to know what developments are right here to remain and which is able to disappear simply as rapidly as they arose.
This weblog breaks down the six concepts you need to know in regards to the fashionable knowledge stack going into 2022 — those that exploded within the knowledge world final yr and don’t appear to be going away.
You most likely know this time period by now, even you don’t precisely know what it means. The thought of the “knowledge mesh” got here from two 2019 blogs by Zhamak Dehghani, Director of Rising Applied sciences at Thoughtworks:
- Transfer Past a Monolithic Knowledge Lake to a Distributed Knowledge Mesh
- Knowledge Mesh Rules and Logical Structure
Its core concept is that corporations can change into extra data-driven by shifting from centralized knowledge warehouses and lakes to a “domain-oriented decentralized knowledge possession and structure” pushed by self-serve knowledge and “federated computational governance”.
As you possibly can see, the language across the knowledge mesh will get complicated quick, which is why there’s no scarcity of “what truly is a knowledge mesh?” articles.
The thought of the info mesh has been quietly rising since 2019, till immediately it was in all places in 2021. The Thoughtworks Know-how Radar moved Knowledge Mesh’s standing from “Trial” to “Assess” in only one yr. The Knowledge Mesh Studying Group launched, and their Slack group received over 1,500 signups in 45 days. Zalando began doing talks about the way it moved to an information mesh.
Quickly sufficient, sizzling takes had been flying backwards and forwards on Twitter, with knowledge leaders arguing over whether or not the info mesh is revolutionary or ridiculous.
In 2022, I feel we’ll see a ton of platforms rebrand and provide their providers because the “final knowledge mesh platform”. However the factor is, the info mesh isn’t a platform or a service you could purchase off the shelf. It’s a design idea with some fantastic ideas like distributed possession, domain-based design, knowledge discoverability, and knowledge product delivery requirements — all of that are value making an attempt to operationalize in your group.
So right here’s my recommendation: As knowledge leaders, it is very important stick with the primary ideas at a conceptual degree, moderately than purchase into the hype that you just’ll inevitably see available in the market quickly. I wouldn’t be shocked if some groups (particularly smaller ones) can obtain the info mesh structure by way of a totally centralized knowledge platform constructed on Snowflake and dbt, whereas others will leverage the identical ideas to consolidate their “knowledge mesh” throughout complicated multi-cloud environments.
Metrics are vital to assessing and driving an organization’s development, however they’ve been struggling for years. They’re usually cut up throughout completely different knowledge instruments, with completely different definitions for a similar metric throughout completely different groups or dashboards.
In 2021, individuals lastly began speaking about how the fashionable knowledge stack might repair this subject. It’s been referred to as the metrics layer, metrics retailer, headless BI, and much more names than I can listing right here.
It began in January, when Base Case proposed “Headless Enterprise Intelligence”, a brand new strategy to fixing metrics issues. A pair months later, Benn Stancil from Mode talked in regards to the “lacking metrics layer” in as we speak’s knowledge stack.
That’s when issues actually took off. 4 days later, Mona Akmal and Aakash Kambuj from Falkon printed articles about making metrics first-class residents and the “fashionable metrics stack”.
Two days after that, Airbnb introduced that it had been constructing a home-grown metrics platform referred to as Minerva to unravel this subject. Different distinguished tech corporations quickly adopted swimsuit, together with LinkedIn’s Unified Metrics Platform, Uber’s uMetric, and Spotify’s metrics catalog of their “new experimentation platform”.
Simply once we thought this fervor had died down, Drew Banin (CPO and Co-Founding father of dbt) opened a PR on dbtcore in October. He hinted that dbt can be incorporating a metrics layer into its product, and even included hyperlinks to these foundational blogs by Benn and Base Case. The PR blew up and reignited the dialogue round constructing a greater metrics layer within the fashionable knowledge stack.
In the meantime, a bunch of early stage startups have launched to compete for this house. Rework might be the most important title thus far, however Metriql, Lightdash, Supergrain, and Metlo additionally launched this yr. Some larger names are additionally pivoting to compete within the metrics layer, equivalent to GoodData’s foray into Headless BI.
I’m extraordinarily excited in regards to the metrics layer lastly turning into a factor. A number of months in the past, George Fraser from Fivetran had an unpopular opinion that all metrics shops will evolve into BI instruments. Whereas I don’t totally agree, I do imagine {that a} metrics layer that isn’t tightly built-in with BI is unlikely to ever change into commonplace.
Nonetheless, present BI instruments aren’t actually incentivized to combine an exterior metrics layer into their instruments… which makes this a rooster and egg downside. Standalone metrics layers will wrestle to encourage BI instruments to undertake their frameworks, and will probably be pressured to construct BI like Looker was pressured to a few years in the past.
This is the reason I’m actually enthusiastic about dbt saying their foray into the metrics layer. dbt already has sufficient distribution to encourage not less than the fashionable BI instruments (e.g. Preset, Mode, Thoughtspot) to combine deeply into the dbt metrics API, which can create aggressive stress for the bigger BI gamers.
I additionally assume that metrics layers are so deeply intertwined with the transformation course of that intuitively this is smart. My prediction is that we’ll see metrics change into a first-class citizen in additional transformation instruments in 2022.
For years, ETL (Extract, Rework, Load) was how knowledge groups populated their techniques. First, they’d pull knowledge from third-party techniques, clear it up, after which load it into their warehouses. This was nice as a result of it saved knowledge warehouses clear and orderly, but it surely additionally meant that it took without end to get knowledge into warehouses. Generally, knowledge groups simply needed to dump uncooked knowledge into their techniques and cope with it later.
That’s why many corporations moved from ETL to ELT (Extract, Load, Rework) a few years in the past. As an alternative of reworking knowledge first, corporations would ship uncooked knowledge into an information lake, then remodel it later for a selected use case or downside.
In 2021, we received one other main evolution on this concept — reverse ETL. This idea first began getting consideration in February, when Astasia Myers (Founding Enterprise Associate at Quiet Capital) wrote an article in regards to the emergence of reverse ETL.
Since then, Hightouch and Census (each of which launched in December 2020) have set off a firestorm as they’ve battled to personal the reverse ETL house. Census introduced that it raised a $16 million Collection A in February and printed a collection of benchmarking studies concentrating on Hightouch. Hightouch countered with three raises of a complete $54.2 million in lower than 12 months.
Hightouch and Census have dominated the reverse ETL dialogue this yr, however they’re not the one ones within the house. Different notable corporations are Grouparoo, HeadsUp, Polytomic, Rudderstack, and Workato (who closed a $200m Collection E in November). Seekwell even received acquired by Thoughtspot in March.
I’m fairly enthusiastic about all the things that’s fixing the “final mile” downside within the fashionable knowledge stack. We’re now speaking extra about how one can use knowledge in each day operations than how one can warehouse it — that’s an unbelievable signal of how mature the basic constructing blocks of the info stack (warehousing, transformation, and many others) have change into!
What I’m not so certain about is whether or not reverse ETL ought to be its personal house or simply be mixed with an information ingestion instrument, given how related the basic capabilities of piping knowledge out and in are. Gamers like Hevodata have already began providing each ingestion and reverse ETL providers in the identical product, and I imagine that we’d see extra consolidation (or deeper go-to-market partnerships) within the house quickly.
Within the final couple of years, the talk round knowledge catalogs was, “Are they out of date?” And it will be straightforward to assume the reply is sure. In a few well-known articles, Barr Moses argued that knowledge catalogs had been lifeless, and Michael Kaminsky argued that we don’t want knowledge dictionaries.
Alternatively, there’s by no means been a lot buzz about knowledge catalogs and metadata. There are such a lot of knowledge catalogs that Rohan from our crew created thedatacatalog.com, a “catalog of catalogs”, which feels each ridiculous and utterly crucial. So which is it — are knowledge catalogs lifeless or stronger than ever?
This yr, knowledge catalogs received new life with the creation of two new ideas — third-generation knowledge catalogs and energetic metadata.
Firstly of 2021, I wrote an article on fashionable metadata for the fashionable knowledge stack. I launched the concept we’re coming into the third-generation of knowledge catalogs, a basic transformation from the prevalent old-school, on-premise knowledge catalogs. These new knowledge catalogs are constructed round numerous knowledge belongings, “huge metadata”, end-to-end knowledge visibility, and embedded collaboration.
This concept received amplified by a big transfer Gartner made this yr — scrapping its Magic Quadrant for Metadata Administration Options and changing it with the Market Information for Energetic Metadata. In doing this, they launched “energetic metadata” as a brand new class within the knowledge house.
What’s the distinction? Previous-school knowledge catalogs gather metadata and produce them right into a siloed “passive” instrument, aka the standard knowledge catalog. Energetic metadata platforms act as two-way platforms — they not solely deliver metadata collectively right into a single retailer like a metadata lake, but additionally leverage “reverse metadata” to make metadata accessible in each day workflows.
Because the first time we wrote about third-generation catalogs, they’ve change into a part of the discourse round what it means to be a contemporary knowledge catalog. We even noticed the phrases pop up in RFPs!
On the similar time, VCs have been keen to speculate on this new house. Metadata administration has grown a ton with raises throughout the board — e.g. Collibra’s $250m Collection G, Alation’s $110m Collection D, and our $16m Collection A at Atlan. Seed-stage corporations like Stemma and Acryl Knowledge additionally launched to construct managed metadata options on present open-source initiatives.
The info world will at all times be numerous, and that range of individuals and instruments will at all times result in chaos. I’m most likely biased, on condition that I’ve devoted my life to constructing an organization within the metadata house. However I really imagine that the important thing to bringing order to the chaos that’s the fashionable knowledge stack lies in how we will use and leverage metadata to create the fashionable knowledge expertise.
Gartner summarized the way forward for this class in a single sentence: “The stand-alone metadata administration platform will probably be refocused from augmented knowledge catalogs to a metadata ‘anyplace’ orchestration platform.”
The place knowledge catalogs within the 2.0 era had been passive and siloed, the three.0 era is constructed on the precept that context must be accessible wherever and every time customers want it. As an alternative of forcing customers to go to a separate instrument, third-gen catalogs will leverage metadata to enhance present instruments like Looker, dbt, and Slack, lastly making the dream of an clever knowledge administration system a actuality.
Whereas there’s been a ton of exercise and funding within the house in 2021, I’m fairly certain we’ll see the rise of a dominant and really third-gen knowledge catalog (aka an energetic metadata platform) in 2022.
As the fashionable knowledge stack goes mainstream and knowledge turns into an even bigger a part of each day operations, knowledge groups are evolving to maintain up. They’re now not “IT people”, working individually from the remainder of the corporate. However this raises the query, how ought to knowledge groups work with the remainder of the corporate? Too usually, they get caught within the “service lure” — unending questions and requests for creating stats, moderately than producing insights and driving affect by way of knowledge.
In 2021, Emilie Schario from Amplify Companions, Taylor Murphy from Meltano, and Eric Weber from Sew Repair talked a couple of strategy to break knowledge groups out of this lure — rethinking knowledge groups as product groups. They first defined this concept with a weblog on Regionally Optimistic, adopted by nice talks at conferences like MDSCON, dbt Coalesce, and Future Knowledge.
A product isn’t measured on what number of options it has or how rapidly engineers can quash bugs — it’s measured on how effectively it meets prospects’ wants. Equally, knowledge product groups ought to be centered on the customers (i.e. knowledge customers all through the corporate), moderately than questions answered or dashboards constructed. This permits knowledge groups to concentrate on expertise, adoption, and reusability, moderately than ad-hoc questions or requests.
This concentrate on breaking out of the service lure and reorienting knowledge groups round their customers actually resonated with the info world this yr. Extra individuals have began speaking about what it means to construct “knowledge product groups”, together with loads of sizzling takes on who to rent and how one can set targets.
Of all of the hyped developments in 2021, that is the one I’m most bullish on. I imagine that within the subsequent decade, knowledge groups will emerge as one of the necessary groups within the group material, powering the fashionable, data-driven corporations on the forefront of the financial system.
Nonetheless, the truth is that knowledge groups as we speak are caught in a service lure, and solely 27% of their knowledge initiatives are profitable. I imagine the important thing to fixing this lies within the idea of the “knowledge product” mindset, the place knowledge groups concentrate on constructing reusable, reproducible belongings for the remainder of the crew. This can imply investing in consumer analysis, scalability, knowledge product delivery requirements, documentation, and extra.
This concept got here out of “knowledge downtime”, which Barr Moses from Monte Carlo first spoke about in 2019 saying, “Knowledge downtime refers to durations of time when your knowledge is partial, misguided, lacking or in any other case inaccurate”. It’s these emails you get the morning after an enormous challenge, saying “Hey, the info doesn’t look proper…”
Knowledge downtime has been part of regular life on an information crew for years. However now, with many corporations counting on knowledge for actually each side of their operations, it’s an enormous deal when knowledge stops working.
But everybody was simply reacting to points as they cropped up, moderately than proactively stopping them. That is the place knowledge observability — the concept of “monitoring, monitoring, and triaging of incidents to stop downtime” — got here in.
I nonetheless can’t imagine how rapidly knowledge observability has gone from being simply an concept to a key a part of the fashionable knowledge stack. (Just lately, it’s even began being referred to as “knowledge reliability” or “knowledge reliability engineering”.)
The house went from being non-existent to internet hosting a bunch of corporations, with a collective $200m of funding raised in 18 months. This contains Acceldata, Anomalo, Bigeye, Databand, Datafold, Metaplane, MonteCarlo, and Soda. Individuals even began creating lists of latest “knowledge observability corporations” to assist preserve observe of the house.
I imagine that previously two years, knowledge groups have realized that tooling to enhance productiveness will not be a good-to-have however a must have. In any case, knowledge professionals are one of the sought-after hires you’ll ever make, in order that they shouldn’t be losing their time on troubleshooting pipelines.
So will knowledge observability be a key a part of the fashionable knowledge stack sooner or later? Completely. However will knowledge observability live on as its personal class or will or not it’s merged right into a broader class (like energetic metadata or knowledge reliability)? That is what I’m not so certain about.
Ideally, if in case you have all of your metadata in a single open platform, you need to be capable to leverage it for quite a lot of use circumstances (like knowledge cataloging, observability, lineage and extra). I wrote about that concept final yr in my article on the metadata lake.
That being mentioned, as we speak, there’s a ton of innovation that these areas want independently. My sense is that we’ll proceed to see fragmentation in 2022 earlier than we see consolidation within the years to return.
It might really feel chaotic and loopy at instances, however as we speak is a golden age of knowledge.
Within the final eighteen months, our knowledge tooling has grown exponentially. All of us make quite a lot of fuss in regards to the fashionable knowledge stack, and for good purpose — it’s so significantly better than what we had earlier than. The sooner knowledge stack was frankly as damaged as damaged might get, and this gigantic leap ahead in tooling is strictly what knowledge groups wanted.
In my view, the subsequent “delta” on the horizon for the info world is the fashionable knowledge tradition stack — one of the best practices, values, and cultural rituals that can assist us numerous people of knowledge collaborate successfully and up our productiveness as we deal with our new knowledge stacks.
Nonetheless, we will solely take into consideration working collectively higher with knowledge after we’ve nailed, effectively, working with knowledge. We’re on the cusp of getting the fashionable knowledge stack proper, and we will’t wait to see what new developments and developments 2022 will deliver!
