Rather than inventing its ten-item list, this guide identifies ten technology areas documented by the Apache, AWS and Google Cloud projects and explains how to evaluate them.
The date matters: a current cloud catalog or project page shows what a platform documents now, not what was most popular in 2022. Treat the list below as a 2022-informed learning map and a way to choose tools for a real workload.
What can—and cannot—be established about the original 2022 list
HackerNoon’s index entry for “10 Most Evolving Big Data Technologies to Catch Up on in 2022” provides the article title and a teaser mentioning data privacy, but not the article body or its ten technologies. You can verify the index at HackerNoon’s big-data story index. Consequently, the ten areas below are an independently sourced landscape, not a claimed reconstruction of that article.
Project documentation also describes capabilities rather than universal rankings. A feature listed by Spark, Flink, Kafka or a cloud vendor does not prove that it is the fastest, cheapest or most widely adopted choice for every organization.

Ten big-data technology areas worth learning
1. Unified analytics engines: Apache Spark
Apache Spark presents itself as a unified analytics engine covering batch processing, streaming, SQL analytics, data science and machine learning. That breadth makes Spark a useful foundation when one organization needs several analytics styles and wants common APIs and execution infrastructure.
- Best fit: batch pipelines, interactive SQL, feature preparation and workloads that combine historical and newer data.
- Check before choosing: required latency, language APIs, data formats, cluster operations and the cost of keeping a general-purpose engine running.
2. Unified bounded and unbounded processing: Apache Flink
In its May 5, 2022 Flink 1.15 announcement, the Apache Flink project emphasized a model that unifies bounded batch data and unbounded streams. The announcement discussed work involving cloud interoperability, autoscaling, SQL and operational behavior.
Flink’s use-case documentation also explains event-time processing, managed state, connectors and deployment in common cluster environments. Those capabilities matter when results depend on out-of-order events, durable state or recovery, but they add operational and design requirements that differ by workload.
3. Event-streaming platforms: Apache Kafka
Kafka organizes data as streams of messages that applications can publish, consume and process through multistage pipelines. The cited Apache Kafka 2.2 use-case documentation describes these patterns and should be read as version-specific documentation, not as a guarantee of current feature status.

Rank #2
- Typical role: durable event transport between producers, processors and downstream systems.
- Design questions: retention, partitioning, delivery guarantees, schema evolution, ordering and connector availability.
4. Stream-processing libraries: Kafka Streams
Kafka’s documentation presents Kafka Streams as a processing library for consuming, transforming and publishing Kafka data. A library approach can be attractive when teams want stream logic inside an application rather than operating a separate processing cluster.
Compare the application’s deployment model, state-store requirements, recovery behavior and language support with a distributed engine such as Flink. The Kafka reference for this description is the versioned 2.2 page cited above, so verify current APIs and guarantees in the release you plan to run.
5. Managed Spark services
Cloud vendors package Spark so teams can provision clusters, submit jobs and connect storage without building every control-plane component themselves. Google Cloud’s current data-analytics catalog is one example of a vendor catalog that documents managed analytics and Spark capabilities.
Managed does not mean responsibility-free. Review the service’s supported Spark version, networking, identity controls, regional data location, autoscaling behavior, billing units and exit path before committing to it.
Rank #3
6. Managed Kafka and cloud event ingestion
The same Google Cloud catalog documents managed analytics and Kafka-related capabilities as part of a broader cloud portfolio. Managed event ingestion can reduce cluster maintenance, but it introduces provider-specific pricing, quotas, connector limits and data-residency decisions.
Evaluate whether the service supports the protocols, retention period, throughput pattern and recovery objectives your producers and consumers require. A managed service is an operating choice, not a different streaming concept.
7. Data lakes
A data lake stores large volumes of source data in relatively open formats and locations so it can be processed by different engines. In its May 17, 2022 white paper, AWS describes modern streaming architectures that combine a data lake with other services rather than expecting one repository to serve every purpose.
Learning priorities include file and table formats, partitioning, metadata, access controls, retention and the difference between raw, curated and serving layers.
8. Cloud data warehouses
Warehouses remain a distinct analytical layer optimized for governed SQL, reporting and repeatable business metrics. AWS’s architecture guidance places warehouses alongside lakes and purpose-built services, illustrating that an architecture may use several stores with different responsibilities.
When comparing a warehouse, examine workload isolation, concurrency, transformation tooling, data-sharing controls, regional availability and the recurring cost of storage plus queries. Do not assume that moving every stream directly into a warehouse is the right latency or cost decision.
9. Purpose-built low-latency data services
Some applications need millisecond-style serving, key-value access, search, time-series queries or other patterns that a lake or warehouse is not designed to provide. The AWS white paper explicitly includes purpose-built services and low-latency data flows as parts of a broader architecture.
Choose this category only after stating the access pattern, consistency requirement, retention policy and recovery objective. It often improves a specific user-facing path while increasing the number of systems that must be secured and operated.

10. Governance, lineage and privacy controls
Governance is the layer that makes large-scale data usable and defensible: identity and access management, cataloging, lineage, retention, quality checks, encryption, audit trails and location controls. AWS’s reference architecture treats governance as a cross-cutting concern rather than an optional add-on.
The index teaser for the original 2022 article mentions data privacy, but it does not establish a particular privacy finding, enforcement action or claim about a named company. For implementation, map the data you collect, the purpose for using it, who can access it, how long it is retained and where it is processed; then obtain advice appropriate to the jurisdictions that apply.

Start with the job, not the product name. The following questions expose the differences that matter operationally.
| Decision axis | Questions to answer |
|---|---|
| Processing mode | Is the workload bounded batch, continuous streaming or both? |
| Latency | Is hourly or daily output sufficient, or must each event affect a result quickly? |
| State and recovery | Does processing require windows, joins, event time, durable state, replay or exactly-once-style guarantees? |
| Interfaces | Will analysts use SQL, or will application engineers write APIs and stream code? |
| Sources and sinks | Which databases, object stores, message systems, formats and connectors are required? |
| Deployment | Will you operate clusters, use a managed service or combine both? |
| Governance | What identity, audit, retention, encryption and data-location controls are mandatory? |
| Economics | What are the steady-state, burst, storage, transfer and operational-support costs? |
The Apache project pages describe distinct capabilities, while the AWS document supplies architecture guidance; none of these sources is a neutral benchmark. A “best” choice therefore requires your workload measurements, reliability targets and governance constraints.
A practical learning sequence
- Learn event and batch concepts: partitions, offsets, schemas, windows, watermarks, joins, replay and idempotency.
- Build one batch pipeline: ingest files into a lake, transform them with Spark and expose governed SQL results.
- Add a streaming path: publish events to Kafka, then implement a small stateful transformation with Kafka Streams or Flink.
- Measure operations: record latency, recovery time, throughput, storage growth, failed-event handling and cloud spend.
- Add governance before scale: document ownership, access, retention, lineage and data-location requirements.
- Reassess managed versus self-operated: compare the engineering time saved with provider lock-in, quotas and recurring charges.
What the 2022 framing still gets right
The durable lesson is architectural: modern platforms often combine event transport, stream or batch processing, lakes, warehouses, specialized serving systems and governance. Spark, Flink and Kafka represent different layers and programming models, while cloud services package some of those layers for particular operating environments.
Use the 2022 date as historical context, not as a current popularity ranking. Check the documentation for the exact versions and cloud regions you will deploy, and validate performance and cost with a representative workload.
