With the tech business at the moment within the midst of its mid-summer lull, now it’s the proper time to take inventory of the place we’ve come this yr and check out the place huge information tech may take us for the rest of 2025.

Some might not just like the time period “huge information,” however right here at BigDATAwire, we’re nonetheless a fan of it. Managing huge quantities of numerous, fast-moving and always-changing information isn’t straightforward, which is why organizations of all stripes spend a lot effort and time to constructing and implementing applied sciences that may make information administration at the least rather less painful.

Amid the drum beat of ever-closer AI-driven breakthroughs, the primary six months of 2025 have demonstrated the very important significance of massive information administration. Listed below are the highest 10 huge information applied sciences to regulate for the second six months of the yr:

1. Apache Iceberg and Open Desk Codecs

Momentum for Apache Iceberg continues to construct after a breakthrough yr in 2024 that noticed the open desk format develop into a defacto normal. Organizations need to retailer their huge information in object shops, i.e. information lakehouses, however they don’t need to quit the standard and management that they had grown accustomed to with less-scalable relational databases. Iceberg primarily lets them have their huge information cake and eat it too.

Simply when Iceberg appeared to have crushed out Apache Hudi and Delta Lake for desk format dominance, one other competitor landed on the pond: DuckLake. The oldsters at DuckDB rolled out DuckLake in late Might to offer one other tackle the matter. The crux of their pitch: If Iceberg requires a database to handle among the metadata, why not simply use a database to handle the entire metadata?

The oldsters behind the Iceberg and its joined-at-the-hip metadata catalog, Apache Polaris, might have been listening. In June, phrase started to emerge that the open supply initiatives are taking a look at streamlining how they retailer metadata by constructing out the scan API spec, which has been described however not really applied. The change, which might be made with Apache Iceberg model 4, would reap the benefits of elevated intelligence in question engines like Spark, Trino, and Snowflake, and would additionally permit direct information exports amongst Iceberg datalakes.

2. Postgres, Postgres In every single place

Who would have thought that the most popular database of 2025 would hint its roots to 1986? However that truly appears to be the case in our present world, which has gone ga-ga for Postgres, the database created by UC Berkeley Professor Michael Stonebraker as a follow-on mission to his first stab at a relational database, Ingres.

Postgres-mania was on full show in Might, when Databricks shelled out a reported $1 billion to purchase Neon, the Nikita Shamgunov startup developed a serverless and infinitely scalable model of Postgres. A number of weeks later, Snowflake discovered $250 million to nab Crunchy Knowledge, which had been constructing a hosted Postgres service for greater than 10 years.

The frequent theme working by each of those huge information acquisitions is an anticipation within the quantity and scale of AI brokers that Snowflake and Databricks shall be deploying on behalf of their clients. These AI brokers will want behind them a database that may be shortly scaled as much as deal with a range information duties, and simply as shortly scaled down and deleted. You don’t need some fancy, new database for that; you need the world’s most dependable, well-understood, and most cost-effective database. In different phrases, you need Postgres.

3. Rise of Unified Knowledge Platforms

The thought of a unified information platform is gaining steam amid the rise of AI. These techniques, ostensibly, are constructed to offer an economical, super-scalable platform the place organizations can retailer enormous quantities of knowledge (measured within the petabytes to exabytes), prepare large AI fashions on enormous GPU clusters, after which deploy AI and analytics workloads, with built-in information administration capabilities besides.

VAST Knowledge, which not too long ago introduced its “working system” for AI, is constructing such a unified information platform. So is its competitor WEKA, which final month launched NeuralMesh, a containerized structure that connects information, storage, compute, and AI companies. One other contender is Pure Storage, which not too long ago launched its enterprise information cloud. Others taking a look at constructing unified information platforms embody Nutanix, DDN, and Hitachi Vantara, amongst others.

As information gravity continues to shift away from the cloud giants towards distributed and on-prem deployments of co-located storage and GPU compute, anticipate these purpose-built huge information platforms to proliferate.

4. Agentic AI, Reasoning Fashions, and MCP, Oh My!

We’re at the moment witnessing the generative AI revolution morphing into the period of agentic AI. By now, most organizations have an understanding of the capabilities and the constraints of enormous language fashions (LLMs), that are nice for constructing chatbots and copilots. As we entrust AI to do extra, we give them company. Or in different phrases, we create agentic AI.

Many huge information software suppliers are adopting agentic AI to assist their clients handle extra duties. They’re utilizing agentic AI to watch information flows and safety alerts, and to make suggestions about information transformations and person entry management selections.

Many of those new agentic AI workloads are powered by a brand new class of reasoning fashions, reminiscent of DeepSeek R-1 and OpenAI GPT-4o that may deal with extra complicated duties. To offer AI brokers entry to the info they want, software suppliers are adopting one thing Mannequin Context Protocol (MCP), a brand new protocol that Anthropic rolled out lower than a yr in the past. This can be a very energetic house, and there may be way more to come back right here, so maintain your eyes peeled.

5. It’s Solely Semantics: Unbiased Semantic Layer Emerges

The AI revolution is shining a light-weight on all layers of the info stack and in some circumstances main us to query why issues are constructed a selected manner and the way they might be constructed higher. One of many layers that AI is exposing is the so-called semantic layer, which has historically functioned as a type of translation layer that takes the cryptic and technical definitions of knowledge saved within the information warehouse and interprets it into the pure language understood and consumed by analysts and different human customers of BI and analytic instruments.

Usually, the semantic layer is applied as a part of a BI mission. However with AI forecast to drive an enormous improve in SQL queries despatched to organizations’ information warehouse or different unified database of document (i.e. lakehouses), the semantic layer immediately finds itself thrust into the highlight as a vital linchpin for guaranteeing that AI-powered SQL queries are, in actual fact, getting the proper solutions.

With a watch towards an unbiased semantic layers changing into a factor, information distributors like dbt Labs, AtScale, Dice, and others are investing of their semantic layers. Because the significance of an unbiased semantic layer grows within the latter half of 2025, don’t be shocked to listen to extra about it.

6. Streaming Knowledge Goes Mainstream

Whereas streaming information has been essential for some purposes for a very long time–assume gaming, cybersecurity, and quantitative buying and selling–the prices have been too excessive for wider use circumstances. However now, after just a few false begins, streaming information seems to lastly be going mainstream–and it’s all because of AI main extra organizations to conclude it’s essential to have the perfect, latest information attainable.

Streaming information platforms like Apache Kafka and Amazon Kinesis are extensively used throughout all industries and use circumstances, together with transactional, analytics, and operational. We’re additionally seeing a brand new class of analytics databases like Clickhouse, Apache Pinot, and Apache Druid achieve traction because of real-time streaming front-ends.

Whether or not an AI software is tapping into the firehose of knowledge or the info is first being landed in a trusted repository like a distributed information retailer, it appears unlikely that batch information shall be adequate for any future use circumstances the place information freshness is even remotely a precedence.

7. Connecting with Graph DBs and Information Shops

The way you retailer information has a big influence on what you are able to do with stated information. As probably the most structured varieties of databases, property graph information shops and their semantic cousins (RDFs, triple shops) mirror how people view the actual world, i.e. by connections individuals have with different individuals, locations, and issues.

That “connectedness” of knowledge can be what makes graph databases so engaging to rising GenAI workloads. As an alternative of asking an LLM to find out related connectivity by 100 or 1,000 pages of immediate, and accepting the fee and latency that essentially entails, GenAI apps can merely question the graph database to find out the relevance, after which apply the LLM magic from there.

A lot of organizations are including graph tech to retrieval-augmented era (RAG) workloads, in what’s referred to as GraphRAG. Startups like Memgraph are adopting GraphRAG with in-memory shops, whereas established gamers like Neo4j are additionally tailoring their options towards this promising use case. Anticipate to see extra GraphRAG within the second half of 2025 and past.

8. Knowledge Merchandise Galore

The democratization of knowledge is a aim at many, if not most organizations. In spite of everything, if permitting some customers to entry some information is sweet, then giving extra customers entry to extra information needs to be higher. One of many methods organizations are enabling information democratization is thru the deployment of knowledge merchandise.

Normally, information merchandise are purposes which might be created to allow customers to entry curated information or insights generated from information. Knowledge merchandise could be developed for an exterior viewers, reminiscent of Netflix’s film suggestion system, or they can be utilized internally, reminiscent of a gross sales information product for regional managers.

Knowledge merchandise are sometimes deployed as a part of an information mesh implementation, which strives to allow unbiased groups to discover and experiment with information use circumstances whereas offering some centralized information governance. A startup referred to as Nextdata is creating software program to assist organizations construct and deploy information merchandise. AI will do lots, but it surely gained’t robotically clear up robust last-mile information issues, which is why information merchandise could be anticipated to develop in reputation.

9. FinOps or Bust

Pissed off by the excessive value of cloud computing, many organizations are adopting FinOps concepts and applied sciences. The core thought revolves round gaining higher understanding of how cloud computing impacts a corporation’s funds and what steps needs to be taken to decrease cloud spending.

The cloud was initially bought as a lower-cost choice to on-prem computing, however that rationale now not holds water, as some specialists estimate that working an information warehouse on the cloud is 50% costlier than working on prem.

Organizations can simply save 10% by taking straightforward steps, reminiscent of adopting the cloud suppliers’ financial savings plans, an professional in Deloitte Consulting’s cloud consulting enterprise not too long ago shared. One other 30% could be reclaimed by analyzing one’s invoice and taking primary steps to curtail waste. Additional reducing value requires fully rearchitecting one’s software across the public cloud platform.

10. I Can’t Consider It’s Artificial Knowledge

As the availability of human-generated information for coaching AI fashions will get decrease, we’re pressured to get inventive to find new sources of coaching information. A type of sources is artificial information.

Artificial information isn’t faux information. It’s actual information that’s artificially created to own the specified options. Earlier than the GenAI revolution, it was being adopted in laptop imaginative and prescient use circumstances, the place customers created artificial photos of uncommon cases or edge use circumstances to coach a pc imaginative and prescient mannequin. Use of artificial information right this moment is rising within the medical subject, the place firms like Synthema are creating artificial information for researching therapy for uncommon hematological ailments.

The potential to use artificial information with generative and agentic AI is a topic of nice curiosity to the info and AI communities, and is a subject to observe within the second half of 2025.

As all the time, these matters are simply a few of what we’ll be writing about right here at BigDATAwire within the second half of 2025. There’ll undoubtedly be some sudden occurrences and maybe some new applied sciences and traits to cowl, which all the time retains issues attention-grabbing.
