Cloud Database Predictions for 2026

In partnership with

What to look out for in Cloud Databases in 2026.

As I am writing this, I just have to think about the whirlwind of AI in nearly every aspect of our lives now. There is the ongoing debate of AI taking jobs, the productization of AI in consumer goods, etc.

The term “Agentic AI” is now being used ad nauseum, and you will find that it is a component of what are some of the things to look out for in 2026. Also, the nature of databases are indeed changing. The bread and butter enterprise database now must be more nimble. This may entail a feature I am seeing more and more is the incorporation of more extensible data types like vectors and JSON.

What I also think is that you may see more databases in addition to Postgres, be key components in the Agentic AI space.

We will also be sure to see more database companies be acquired by what I call the monoliths. Let me let you in on a little secret. If you have been reading for a while, a fair chunk of what I call “Exotic Databases” are at their core start ups, ready for acquisition.

I am constantly looking at not just the technologies that these companies offer, but I find that as time goes on, I am looking at the financials of these companies, and A LOT of them are at various series of funding.

Now here are my Cloud Database Predictions for 2026:

Hybrid and Multi-Cloud Architectures as Standard: Organizations will adopt hybrid models combining public clouds for scalability, private for security, and edge for real-time processing, with seamless failover across providers to meet compliance needs. This trend will favor distributed databases like CockroachDB, YugabyteDB, and pgEdge for portability and resilience.

Full Shift of AI Workloads to Cloud Databases: Expect a complete migration of AI tasks like machine learning model training and natural language processing to cloud environments, reducing reliance on on-premises setups and enabling pay-as-you-go data processing for efficiency. This will boost demand for databases like Snowflake and Databricks that support seamless AI integration.

Rise of Agentic AI in Database Management: AI agents will become primary users of databases, handling autonomous tasks such as schema evolution, querying, and scaling. Databases will need hyper-elasticity and scale-to-zero capabilities to manage bursty, non-human workloads without cost overruns. Look for innovations in platforms like TiDB or MongoDB to support this agent-ready data paradigm.

Agentic AI Becomes a First-Class Workload and Primary Data Consumer: Databases will evolve to treat agentic AI not as experimental demos but as core workloads, shipping primitives like tool/function calling, policy-aware retrieval, hybrid memory (vector + structured), and guarded execution loops for autonomous operations. By 2026, autonomous AI agents will surpass human analysts as the main database users, driving a shift to "context engineering" for millisecond-fresh streaming data to fuel workflows. What to watch: Product shifts from "copilots" to "agents," with enhanced guardrails, audit logs, and orchestration embedded in the data plane. Vendors like MongoDB, Couchbase, or Databricks may lead by integrating agent orchestration directly, enabling delegation shifts and autonomous loops.

The Semantic Layer Emerges as Core Infrastructure and Battleground: Teams will standardize semantic or metrics layers to prevent "definition chaos" in AI and BI, with vendors increasingly embedding semantics into platforms for consistent data interpretation. This will position the semantic layer as essential AI infrastructure, accelerating AI-ready architectures and ensuring modular, future-proof foundations. What to watch: Roadmaps for metric stores and semantic layers, including native governance, tighter BI/AI integrations, and vector database management. Companies like Coalesce, Atlan, or Collibra could become key players in this space, treating semantics as upgraded "brain transplants" for data stacks.

Open Table Formats Win, with Interoperability as a Key Buying Criterion: Formats like Apache Iceberg and Delta Lake will dominate, emphasizing openness and cross-engine compatibility to minimize vendor lock-in and enable mixed data stacks. This evolution will make "write once, query anywhere" a reality, building on file formats like Parquet for reliable lakehouse operations. What to watch: Deeper support for catalogs, governance, time travel, and production-tested interoperability claims. Platforms from Snowflake, Databricks, or Starburst may highlight these features, alongside emerging formats like Hudi and Paimon for batch reliability and schema evolution.

Real-Time OLAP Becomes the Standard: The batch processing era will fade as businesses require sub-second analytics on fresh data, pushing real-time OLAP as a default for interactive querying on large, streaming datasets. This shift will eliminate ETL bottlenecks, enabling zero-ETL paths from streams to dashboards. What to look for: Intensifying "streaming database wars" with integrations between stream processors (e.g., RisingWave, Decodable, Kafka/Flink) and OLAP engines (e.g., ClickHouse, StarRocks, Pinot). Focus on platforms like Druid or Rockset for low-latency, scalable analytics in embedded or enterprise setups.

Final Thoughts

Just like I said last Wednesday, thanks again for sticking with the newsletter. It is a challenge to keep this going week after week. But I enjoy the challenge as combing through over 1000 articles a week keeps me sharp for this forum, as well as what I do in the “real world”. The newsletter is a tremendous help to be quite honest.

I hope you enjoy it, as much as I love putting it together. In 2026, I really feel that the database world is going to be more exciting and there will be a lot more things to be cognizant of.

With that said, continue to enjoy the festive season, if and while you can, and also, I wish you a heartfelt Happy New Year!
