Hadoop Walked So Databricks Could Run

Are you familiar with this scenario: Your data team spends 80% of their time fixing infrastructure issues instead of extracting insights.

In today’s data-driven world, organisations are drowning in data but starving for actionable insights. Traditional warehouses and siloed tools promised answers, but in reality, they often created more problems than they solved. That’s where Databricks comes in, a unified analytics platform that is fundamentally changing how organisations approach data processing, machine learning, and collaborative analytics.

But what exactly makes Databricks special, and why are companies like Shell and H&M making the switch? Let’s dive deep.

The Hadoop Era is Over

For a long time, Hadoop was the go-to framework for big data. It worked well for its time, that is, when storage was costly, and speed wasn’t the priority. But today, the game has changed. Storage is cheap, computing power is fast, and businesses need answers immediately.

Hadoop just can’t keep up anymore. Here’s why:

  1. It’s built for batch jobs.
    Hadoop’s MapReduce framework was fundamentally built for batch processing. That worked when businesses could afford to wait hours for reports. But today, when fraud must be stopped instantly, and shoppers expect real-time personalisation, waiting hours simply means losing business.
  2. It’s complicated.
    Running Hadoop means dealing with YARN, HDFS, and a mess of other moving parts that require deep technical expertise. Teams end up maintaining systems instead of generating insights.
  3. It’s slow by design.
    Hadoop writes to disk for every step, which adds painful I/O bottlenecks. While this design was necessary in an era of expensive memory, today’s workloads demand speed and agility that Hadoop simply wasn’t built to deliver.
  4. It’s limited to basic data transformations.
    Hadoop can do basic data crunching, but advanced analytics and machine learning require extra tools stitched on top. As a result, companies using Hadoop often find themselves stitching together additional tools, creating even more complexity.

How Spark Became the Game Changer

If Hadoop represented the first wave of big data, then Apache Spark is the revolution that redefined it. Spark fundamentally rethought how large-scale computation should be handled, and in doing so, unlocked the speed and flexibility that modern businesses demand.

In-Memory Processing

Unlike Hadoop’s disk-heavy MapReduce model, Spark keeps data in memory between operations. This design makes it 10–100x faster for iterative workloads such as machine learning, graph processing, and interactive analytics.

A Unified Engine

Spark consolidates what once required multiple tools into a single, powerful engine. From batch processing and real-time streaming to SQL analytics and machine learning, Spark eliminates the patchwork complexity that Hadoop imposed.

Simplified Development

Spark was designed to be developer and data-scientist friendly. With APIs in Python, Scala, Java, and R, it brings big data processing into the hands of more people, reducing the reliance on niche Hadoop expertise.

Real-Time Capabilities

With Spark Streaming, organisations can process and react to data as it happens. From fraud detection to personalised recommendations, Spark delivers the real-time capabilities that Hadoop simply cannot match.

The Reality of Today’s Data Landscape

Modern organisations face challenges that go far beyond Hadoop’s design assumptions:

  • Massive Scale: Petabytes of structured and unstructured data flowing in from every channel.
  • Real-Time Demands: Customers expect instant responses, and businesses need immediate analytics.
  • Team Silos: Data engineers, analysts, and data scientists often work in isolation, slowing down outcomes.
  • Speed Requirements: Business decisions can’t wait for overnight batch jobs. They need to happen now.

The Hadoop era taught us valuable lessons about distributed computing, but clinging to it in 2025 is like insisting on using dial-up internet just because it still works.

Enter Databricks: Spark-Powered Analytics at Scale

Databricks isn’t just another tool in the data stack — it’s the natural next step in the Spark journey. Built by the original creators of Apache Spark, the platform takes everything that made Spark powerful and wraps it in a package that’s easier for businesses to actually use at scale. Think of it as “Spark, upgraded”: same speed and flexibility, but now with collaboration, governance, and enterprise-grade reliability baked in.

The Lakehouse Revolution: What it means to be ‘Unified’

The real game-changer is the Lakehouse architecture. For years, companies had to choose between two imperfect options:

  • Data lakes were cheap and great at storing all kinds of messy, unstructured data, but not so great at performance or governance.
  • Data warehouses were fast, reliable, and structured, but expensive and rigid, not built to handle today’s flood of unstructured information.

The usual solution? Use both, and spend huge amounts of time stitching them together. That meant silos, complexity, and constant frustration.

Databricks flips that script. The Lakehouse combines the flexibility and scale of a data lake with the performance and reliability of a warehouse — all in one platform. And it doesn’t stop at BI dashboards. Because it handles unstructured and semi-structured data just as easily as structured data, the Lakehouse also unlocks AI and machine learning use cases that warehouses simply can’t.

At the centre of it all is Delta Lake, Databricks’ open-source storage layer. It gives raw data lakes the features they’ve always lacked:

  • ACID transactions so data operations are reliable.
  • Schema enforcement and evolution to keep datasets clean and consistent.
  • Time travel so teams can roll back, audit, or reproduce past versions of data with ease.

The result? No more choosing between flexibility and control. No more forcing BI and AI into separate worlds. With Databricks, organisations finally get both, and teams can focus on insights instead of plumbing.

Real-Life Impact: How H&M Uses Databricks to Stay Ahead of Fashion Trends

Imagine a global fashion retailer like H&M. Every day, they deal with massive amounts of data: sales transactions from thousands of stores, online browsing behaviour from millions of customers, and supply chain data from hundreds of factories worldwide. Traditionally, this data sat in different systems: some in warehouses for reporting, some in lakes for raw storage, making it difficult to bring everything together fast enough to make smart business decisions.

H&M turned to Databricks’ Lakehouse Platform to unify all this data in one place. By doing so, they can now:

  • Spotting demand before it happens
    With Databricks, H&M can now predict regional demand for styles, colours, and sizes, so they produce what customers actually want, instead of overproducing items that may never sell.
  • Balancing stock across cities
    If a store in London is selling out of black jackets while another in Paris has too many, Databricks helps rebalance stock before it becomes a problem.
  • Making shopping feel personal
    Using Databricks’ machine learning capabilities, H&M can recommend items to online shoppers based on browsing history, improving customer satisfaction and boosting sales.

The impact? H&M reduced waste, improved supply chain efficiency, and delivered a more personalised experience to millions of customers, all powered by Databricks.

The Future is Unified

As data grows in volume, velocity, and variety, the demand for unified analytics platforms will only accelerate. Organisations that embrace the Lakehouse today will unlock faster insights, fuel AI-driven innovation, and stay ahead of the curve. Those who don’t? They’ll be left clinging to outdated systems, like trying to make dial-up work in a 5G world.
