What is OpenHouse?

OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization

OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).

What is OpenMetadata?

OpenMetadata 2.0.0 ships Dynamic Sampling by default and a full Data Quality overhaul.

OpenMetadata has shipped its 2.0.0 GA alongside continued 1.13.x maintenance. The headline change in 2.0.0 is defaulting to Dynamic Sampling in the Profiler — 100% table scans are out, which meaningfully reduces compute cost on large tables. Cardinality metrics are no longer collected by default. MCP is now a first-class service entity with OAuth, SAML SSO, and usage analytics. The 1.13.x branch remains active for teams not yet migrating.

OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization

◆ Current state

OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).

◆ Where it's heading

The entityType discriminator in v0.5.490 is the most directional move in this window — it creates the data model prerequisite for treating views as first-class entities alongside tables, something OpenHouse has not supported. Storage lifecycle work is converging on Iceberg-native mechanisms, reducing custom expiration logic. The post-commit operations framework in v0.5.492 is infrastructure that will allow OpenHouse to add downstream hooks (compaction triggers, notifications) without catalog coupling.

◆ Prediction

Iceberg view read support will arrive in the next several releases, building on the discriminator and HTS scaffolding now in place. The authorization model for views will be an open question — watch whether they reuse the table ACL path or introduce a parallel model.

OpenMetadata 2.0.0 ships Dynamic Sampling by default and a full Data Quality overhaul.

◆ Current state

OpenMetadata has shipped its 2.0.0 GA alongside continued 1.13.x maintenance. The headline change in 2.0.0 is defaulting to Dynamic Sampling in the Profiler — 100% table scans are out, which meaningfully reduces compute cost on large tables. Cardinality metrics are no longer collected by default. MCP is now a first-class service entity with OAuth, SAML SSO, and usage analytics. The 1.13.x branch remains active for teams not yet migrating.

◆ Where it's heading

OpenMetadata 2.0.0 shifts the platform toward cost-aware data quality by default — this is a philosophical change, not just a feature: the assumption is no longer that you scan everything. MCP as a first-class service category signals intent to be the metadata and observability layer for AI pipelines, not just traditional BI/warehouse workflows.

◆ Prediction

Post-2.0.0 development will focus on the MCP service layer and AI pipeline observability. Expect deeper integration between the Profiler's Dynamic Sampling and cost estimation, and broader MCP adapter coverage. The 1.13.x branch will likely enter long-term-support status within one or two more maintenance releases.
