The challenge of performance in an agentic analytics environment isn't that you have too little control over your query engine. It's that you can't use control you don't have time to exercise. AI agents generate novel queries faster than any human performance review cycle can respond to.

The data lakehouse resolves the core tradeoff that made the warehouse-vs-lake debate so frustrating.

This guide explores what semantic layers are, their benefits and how they’re implemented within your enterprise data stack.

We have news. The Gartner® Market Guide for Agentic Analytics, published February 9, 2026, maps the platforms shaping an emerging category: software that applies AI agents across the data-to-insight workflow. Among approximately 37 vendors listed, Dremio is recognized for its Agentic Lakehouse Platform as a Representative Vendor. We believe this reflects the data foundation we […]

The metadata structure of a table format determines everything: how fast queries start planning, how efficiently concurrent writes are handled, how schema changes propagate, and how much overhead accumulates over time.

Using Claude Code to Build an Iceberg Lakehouse For years, building a production-grade data lakehouse required a specialized team: data engineers to design pipelines and to tune queries, and platform architects to manage table maintenance. Apache Iceberg changed the storage and table format equation, giving teams an open, vendor-neutral foundation for any scale of data. […]

Most analytics workloads are fine with millisecond timestamps. A daily sales report doesn't care whether a transaction landed at 14:32:07.001 or 14:32:07.001423. But for the teams that do care about sub-millisecond precision, the lakehouse has historically been a weak link. Timestamps either got truncated on ingestion, stored as strings to preserve precision, or shoehorned into […]

Polaris is production-ready today. Organizations are already using its RBAC, catalog federation, credential vending, Iceberg SQL views, and generic tables to govern multi-engine lakehouses at scale.

A table format is a specification that defines how to organize metadata about data files so that query engines can treat them as reliable, transactional tables. It sits between the query engine and the physical files.

Adding a column to a large production table used to require a plan. You'd write the migration script, schedule a maintenance window, kick off a backfill job that rewrote every data file to include the new column, and then wait. For a table with billions of rows on a busy lake, that wait could stretch […]

Something I keep hearing in conversations with customers and prospects right now is a version of the same frustration: we have executive buy-in, budget approved, models selected, and we still cannot ship anything meaningful. The AI initiative is stalled, and everyone is looking at the data team. Then there are the teams who are already […]
