The real bottleneck with enterprise AI isn't retrieval augmentation or model accuracy : it's governance. Policy-as-code (OPA, ABAC, Rego) lets you enforce access rules, column masks, and row filters on any data source at query time.

Anatomy of an Agentic Lakehouse

June 08, 2026

The four-layer architecture of the agentic lakehouse: object storage, Apache Iceberg table format, Apache Polaris catalog, and the semantic/agent layer. How each layer provides guarantees for AI agent access.

Agentic Lakehouse Concurrency and Isolation

June 08, 2026

How Iceberg optimistic concurrency control, partition-level isolation, and idempotency keys enable safe concurrent writes from multiple AI agents to the same lakehouse tables.

Lakehouse Context Layers with Atlan and Iceberg v3

June 08, 2026

Lakehouse context layers bridge the gap between raw Iceberg tables and AI agents that need business meaning. Atlan and Snowflake Horizon each take different approaches to the same problem.

Real-Time Agentic Analytics with ClickHouse

Metric catalogs define what terms mean. Composable analytics defines how terms combine, transform, and relate. For AI agents, composability is what turns definitions into reasoning.

Goal-Directed Analytics Agents on Apache Iceberg

June 08, 2026

How goal-directed analytics agents decompose business questions into sub-tasks, execute action loops over Apache Iceberg tables, and use the lakehouse as both a data source and a state store for agent action logs.

Iceberg Remote Signing for Regulated Datasets

June 08, 2026

Iceberg REST catalog remote signing provides per-file pre-signed URL access for regulated datasets. How it differs from credential vending, audit trail capabilities, and Snowflake implementation for PII/compliance workloads.

Apache Iceberg v3 Deletion Vectors on Snowflake

June 08, 2026

Apache Iceberg v3 deletion vectors replace positional delete files with binary bitmaps in Puffin files, delivering up to 10x faster DML on Snowflake. Deep dive into architecture, benchmarks, and migration.
