What’s modified?

Since 2021, possibly a greater query is what HASN’T modified?

Stepping out of the shadow of COVID, our society has grappled with a myriad of challenges — political and social turbulence, fluctuating monetary landscapes, the surge in AI developments, and Taylor Swift rising as the largest star within the … *checks notes* … Nationwide Soccer League!?!

Over the past three years, my life has modified as nicely. I’ve navigated the info challenges of varied industries, lending my experience by means of work and consultancy at each massive companies and nimble startups.

Concurrently, I’ve devoted substantial effort to shaping my id as a Information Educator, collaborating with a few of the most famed corporations and prestigious universities globally.

Because of this, right here’s a brief checklist of what impressed me to put in writing an modification to my unique 2021 article:

Corporations, massive and small, are beginning to attain ranges of information scale beforehand reserved for Netflix, Uber, Spotify and different giants creating distinctive companies with knowledge. Merely cobbling collectively knowledge pipelines and cron jobs throughout numerous purposes not works, so there are new issues when discussing knowledge platforms at scale.

Though I briefly talked about streaming in my 2021 article, you’ll see a renewed focus within the 2024 model. I’m a robust believer that knowledge has to maneuver on the velocity of enterprise, and the one method to actually accomplish this in fashionable instances is thru knowledge streaming.

I discussed modularity as a core idea of constructing a contemporary knowledge platform in my 2021 article, however I failed to emphasise the significance of information orchestration. This time round, I’ve a complete part devoted to orchestration and why it has emerged as a pure praise to a contemporary knowledge stack.

The Platform

To my shock, there may be nonetheless no single vendor answer that has area over the complete knowledge vista, though Snowflake has been making an attempt their greatest by means of acquisition and improvement efforts (Snowpipe, Snowpark, Snowplow). Databricks has additionally made notable enhancements to their platform, particularly within the ML/AI area.

All the parts from the 2021 articles made the minimize in 2024, however even the acquainted entries look a little bit completely different 3 years later:

  • Supply
  • Integration
  • Information Retailer
  • Transformation
  • Orchestration
  • Presentation
  • Transportation
  • Observability


The mixing class will get the largest improve in 2024, splitting into three logical subcategories:


The power to course of incoming knowledge alerts from numerous sources at a every day/hourly interval is the bread and butter of any knowledge platform.

Fivetran nonetheless looks like the simple chief within the managed ETL class, but it surely has some stiff competitors by way of up & comers like Airbyte and massive cloud suppliers which were strengthening their platform choices.

Over the previous 3 years, Fivetran has improved its core providing considerably, prolonged its connector library and even began to department out into mild orchestration with options like their dbt integration.

It’s additionally value mentioning that many distributors, equivalent to Fivetran, have merged the most effective of OSS and enterprise capital funding into one thing known as Product Led Development, providing free tiers of their product providing that decrease the barrier to entry into enterprise grade platforms.

Even when the issues you might be fixing require many customized supply integrations, it is sensible to make use of a managed ETL supplier for the majority and customized Python code for the remaining, all held collectively by orchestration.


Kafka/Confluent is king with regards to knowledge streaming, however working with streaming knowledge introduces quite a few new issues past subjects, producers, customers, and brokers, equivalent to serialization, schema registries, stream processing/transformation and streaming analytics.

Confluent is doing a very good job of aggregating the entire parts required for profitable knowledge streaming beneath one roof, however I’ll be stating streaming issues all through different layers of the info platform.

The introduction of information streaming doesn’t inherently demand a whole overhaul of the info platform’s construction. In reality, the synergy between batch and streaming pipelines is crucial for tackling the varied challenges posed to your knowledge platform at scale. The important thing to seamlessly addressing these challenges lies, unsurprisingly, in knowledge orchestration.


In lots of instances, the info platform itself must be accountable for, or on the very least inform, the technology of first social gathering knowledge. Many may argue that this can be a job for software program engineers and app builders, however I see a synergistic alternative in permitting the individuals who construct your knowledge platform to even be accountable for your eventing technique.

I break down eventing into two classes:

  • Change Information Seize — CDC

The essential gist of CDC is utilizing your database’s CRUD instructions as a stream of information itself. The primary CDC platform I got here throughout was an OSS undertaking known as Debezium and there are various gamers, massive and small, vying for area on this rising class.

  • Click on Streams — Phase/Snowplow

Constructing telemetry to seize buyer exercise on web sites or purposes is what I’m referring to as click on streams. Phase rode the press stream wave to a billion greenback acquisition, Amplitude constructed click on streams into a whole analytical platform and Snowplow has been surging extra lately with their OSS strategy, demonstrating that this area is ripe for continued innovation and eventual standardization.

AWS has been a frontrunner in knowledge streaming, providing templates to ascertain the outbox sample and constructing knowledge streaming merchandise equivalent to MSK, SQS, SNS, Lambdas, DynamoDB and extra.

Information Retailer

One other vital change from 2021 to 2024 lies within the shift from “Information Warehouse” to “Information Retailer,” acknowledging the increasing database horizon, together with the rise of Information Lakes.

Viewing Information Lakes as a technique moderately than a product emphasizes their function as a staging space for structured and unstructured knowledge, doubtlessly interacting with Information Warehouses. Choosing the suitable knowledge retailer answer for every facet of the Information Lake is essential, however the overarching know-how resolution entails tying collectively and exploring these shops to rework uncooked knowledge into downstream insights.

Distributed SQL engines like Presto , Trino and their quite a few managed counterparts (Pandio, Starburst), have emerged to traverse Information Lakes, enabling customers to make use of SQL to affix numerous knowledge throughout numerous bodily areas.

Amid the push to maintain up with generative AI and Massive Language Mannequin developments, specialised knowledge shops like vector databases develop into important. These embrace open-source choices like Weaviate, managed options like Pinecone and lots of extra.


Few instruments have revolutionized knowledge engineering like dbt. Its impression has been so profound that it’s given rise to a brand new knowledge function — the analytics engineer.

dbt has develop into the go-to selection for organizations of all sizes looking for to automate transformations throughout their knowledge platform. The introduction of dbt core, the free tier of the dbt product, has performed a pivotal function in familiarizing knowledge engineers and analysts with dbt, hastening its adoption, and fueling the swift improvement of recent options.

Amongst these options, dbt mesh stands out as significantly spectacular. This innovation permits the tethering and referencing of a number of dbt initiatives, empowering organizations to modularize their knowledge transformation pipelines, particularly assembly the challenges of information transformations at scale.

Stream transformations characterize a much less mature space compared. Though there are established and dependable open-source initiatives like Flink, which has been in existence since 2011, their impression hasn’t resonated as strongly as instruments coping with “at relaxation” knowledge, equivalent to dbt. Nevertheless, with the rising accessibility of streaming knowledge and the continued evolution of computing sources, there’s a rising crucial to advance the stream transformations area.

For my part, the way forward for widespread adoption on this area is determined by applied sciences like Flink SQL or rising managed companies from suppliers like Confluent, Decodable, Ververica, and Aiven. These options empower analysts to leverage a well-recognized language, equivalent to SQL, and apply these ideas to real-time, streaming knowledge.


Reviewing the Ingestion, Information Retailer, and Transformation parts of establishing an information platform in 2024 highlights the daunting problem of selecting between a large number of instruments, applied sciences, and options.

From my expertise, the important thing to discovering the suitable iteration in your situation is thru experimentation, permitting you to swap out completely different parts till you obtain the specified end result.

Information orchestration has develop into essential in facilitating this experimentation through the preliminary phases of constructing an information platform. It not solely streamlines the method but in addition presents scalable choices to align with the trajectory of any enterprise.

Orchestration is usually executed by means of Directed Acyclic Graphs (DAGs) or code that constructions hierarchies, dependencies, and pipelines of duties throughout a number of programs. Concurrently, it manages and scales the sources utilized to run these duties.

Airflow stays the go-to answer for knowledge orchestration, obtainable in numerous managed flavors equivalent to MWAA, Astronomer, and provoking spin-off branches like Prefect and Dagster.

With out an orchestration engine, the flexibility to modularize your knowledge platform and unlock its full potential is restricted. Moreover, it serves as a prerequisite for initiating an information observability and governance technique, enjoying a pivotal function within the success of the complete knowledge platform.


Surprisingly, conventional knowledge visualization platforms like Tableau, PowerBI, Looker, and Qlik proceed to dominate the sphere. Whereas knowledge visualization witnessed fast development initially, the area has skilled relative stagnation over the previous decade. An exception to this development is Microsoft, with commendable efforts in direction of relevance and innovation, exemplified by merchandise like PowerBI Service.

Rising knowledge visualization platforms like Sigma and Superset really feel just like the pure bridge to the longer term. They allow on-the-fly, resource-efficient transformations alongside world-class knowledge visualization capabilities. Nevertheless, a potent newcomer, Streamlit, has the potential to redefine all the pieces.

Streamlit, a strong Python library for constructing front-end interfaces to Python code, has carved out a beneficial area of interest within the presentation layer. Whereas the technical studying curve is steeper in comparison with drag-and-drop instruments like PowerBI and Tableau, Streamlit presents countless potentialities, together with interactive design components, dynamic slicing, content material show, and customized navigation and branding.

Streamlit has been so spectacular that Snowflake acquired the corporate for practically $1B in 2022. How Snowflake integrates Streamlit into its suite of choices will doubtless form the way forward for each Snowflake and knowledge visualization as a complete.


Transportation, Reverse ETL, or knowledge activation — the ultimate leg of the info platform — represents the essential stage the place the platform’s transformations and insights loop again into supply programs and purposes, actually impacting enterprise operations.

At present, Hightouch stands out as a frontrunner on this area. Their sturdy core providing seamlessly integrates knowledge warehouses with data-hungry purposes. Notably, their strategic partnerships with Snowflake and dbt emphasize a dedication to being acknowledged as a flexible knowledge instrument, distinguishing them from mere advertising and gross sales widgets.

The way forward for the transportation layer appears destined to intersect with APIs, making a situation the place API endpoints generated by way of SQL queries develop into as widespread as exporting .csv recordsdata to share question outcomes. Whereas this transformation is anticipated, there are few distributors exploring the commoditization of this area.


Just like knowledge orchestration, knowledge observability has emerged as a necessity to seize and observe all of the metadata produced by completely different parts of an information platform. This metadata is then utilized to handle, monitor, and foster the expansion of the platform.

Many organizations handle knowledge observability by establishing inner dashboards or counting on a single level of failure, equivalent to the info orchestration pipeline, for remark. Whereas this strategy could suffice for fundamental monitoring, it falls brief in fixing extra intricate logical observability challenges, like lineage monitoring.

Enter DataHub, a preferred open-source undertaking gaining vital traction. Its managed service counterpart, Acryl, has additional amplified its impression. DataHub excels at consolidating metadata exhaust from numerous purposes concerned in knowledge motion throughout a company. It seamlessly ties this data collectively, permitting customers to hint KPIs on a dashboard again to the originating knowledge pipeline and each step in between.

Monte Carlo and Nice Expectations serve the same observability function within the knowledge platform however with a extra opinionated strategy. The rising reputation of phrases like “end-to-end knowledge lineage” and “knowledge contracts” suggests an imminent surge on this class. We are able to anticipate vital development from each established leaders and modern newcomers, poised to revolutionize the outlook of information observability.


The 2021 model of this text is 1,278 phrases.

The 2024 model of this text is nicely forward of 2K phrases earlier than this closing.

I assume meaning I ought to maintain it brief.

Constructing a platform that’s quick sufficient to fulfill the wants of at this time and versatile sufficient to develop to the calls for of tomorrow begins with modularity and is enabled by orchestration. In an effort to undertake essentially the most modern answer in your particular drawback, your platform should make room for knowledge options of all shapes in sizes, whether or not it’s an OSS undertaking, a brand new managed service or a set of merchandise from AWS.

There are numerous concepts on this article however in the end the selection is yours. I’m keen to listen to how this evokes folks to discover new potentialities and create new methods of fixing issues with knowledge.
